ARLP026 Propagation de K7RA

A new sunspot group emerged on June 24, but don’t count on it
persisting much longer. It emerged already far along the western
limb, and is about to rotate off the visible solar disc. Sunspot
numbers on June 24-27 were 24, 12, 11 and 11.

Average daily sunspot number increased from 0 to 6.7 over the week
of June 20-26, while average daily solar flux increased from 67.1 to
67.4.

Average daily planetary A index decreased from 5.3 to 5, and average
daily middle latitude A index decreased from 7 to 5.7.

Predicted solar flux is 67 on June 28 through July 5, 68 on July 6,
69 on July 7-9, 68 on July 10-11, 67 on July 12-27, 68 on July 28,
69 on July 29-31, 68 on August 1-2, 69 on August 3-5, 68 on August
6-7, and 67 on August 8-11.

Predicted planetary A index is 5 on June 28-30, 8 on July 1, 5 on
July 2-5, 8 on July 6, 5 on July 7-9, 8 on July 10-11, 5 on July

Geomagnetic activity forecast for June 28 until July 24, 2019 from
F.K. Janda, OK1HH, who has been compiling this weekly geomagnetic
forecast since January 1978.

“Geomagnetic field will be:

“Quiet on June 28, 30, July 9, 14-16, 21
Quiet to unsettled on June 29, July 3, 8, 10-11, 13, 17, 20
Quiet to active on June July 1 (- 2), 4-6, 12, 18, 24
Unsettled to active on July 7, 19, 22-23
No disturbed conditions predicted.

“Solar wind will intensify on June (28,) July 5-7, (8-9,) 10-11,
(17-19, 22-24)

“Parenthesis means lower probability of activity enhancement.”

On Tuesday, June 25, NN4X reported from Florida:

“Amazing over-the-pole conditions on 17M this morning (6/25/2019).

“Decoded dozens of JAs on FT8 between 1200Z and 1245Z and worked a
few. UA0BA (NP49) was logged at 1512Z, worked HS0ZIV at 1519Z, and
was called by BH4QYX immediately afterwards, but did not complete
that QSO.”

ARLP022 Propagation de K7RA

No sunspots appeared over this past reporting week, May 23 to 29.

Compared to the previous seven days, average daily solar flux
dropped from 69.8 to 67.4.  Average daily planetary A index
increased from 5 to 7.3, and average mid-latitude A index went from
6.1 to 8.1.

Predicted solar flux over the next 45 days is 70 on May 31, 71 on
June 1, 72 on June 2 to 6, 76 on June 7 to 10, 74 on June 11, 72 on
June 12 and 13, 70 on June 14 and 15, 69 on June 16 and 17, 68 on
June 18, 67 on June 19 to 26, 68 and 70 on June 27 and 28, 72 on
June 29 through July 10, then 70 and 68 on July 11 and 12 and 67 on
July 13 and 14.

Predicted planetary A index is 8 on May 31, 5 on June 1 to 4, 8 on
June 5 and 6, 5 on June 7 to 15, 8 on June 16 to 18, 5 on June 19 to
23, then 10, 16, 12, 10, 10 and 8 on June 24 to 29 and 5 on June 30
through July 14.

When might we see a return of visible sunspots?  Perhaps a table of
recent sunspot numbers and solar flux gives us a clue:

ftp://ftp.swpc.noaa.gov/pub/indices/old_indices/2019Q2_DSD.txt

Note when the solar flux dropped below 70, sunspots disappeared.
With predicted flux values above 70 for the first half of June,
perhaps we won’t have long to wait.

OK1HH sends us his geomagnetic forecast.

“Geomagnetic activity forecast for the period May 31 thru June 26,
2019.

Geomagnetic field will be:
Quiet on June 13 and 14
Quiet to unsettled on May 31, June 1 to 6, 9, 15, 19 to 22
Quiet to active on June 8, 11 and 12, 16 to 18
Unsettled to active on June 7, 10, 23 to 26

Solar wind will intensify on (May 31 to June 1,) June 10 to 14, 24
to 26

Parenthesis means lower probability of activity enhancement.”

N8II sent us his observations on last weekend’s CQ WW WPX CW
contest, from West Virginia:

“Band conditions during the 2 weeks leading up to the WPX CW contest
were quite poor from here except for a few sporadic E openings
including one on 10M phone double hop to OR and WA.

Right from the start, conditions were exceptional.  In the first few
minutes I worked New Zealand and Hawaii on 15 meters, both weak.  20
meters was wide open to almost all of Europe excluding Britain and
France/Benelux countries until about 0115Z, then still open well to
some of EU (northern loud).  Asia conditions improved then including
some Russians in zone 18 and Kazakhstan.  There was some short skip
into the USA and Canada indicating some sporadic E help.  N3QE in MD
nearby reported best ever WPX CW 80M conditions and 40M excellent as
well Friday night.

Saturday morning the sporadic E fun continued as it did throughout
whenever I was operating until the end at 2400Z Sunday.  Also 2 big
gun Japanese stations were logged with good signals around 1240Z.
Over the weekend, I made 204 QSO’s on 15M, about 65 USA and Canada,
and 45 QSO’s on 10.  The first European to go into the 15M log was
SP8R in Poland at 1256Z followed quickly by UW3U Ukraine.  There
were very few loud EU signals on 15 Saturday, but many that I
struggled to work then were much louder on Sunday.  Conditions
Saturday favored Central EU with Hungary, Czech and Slovak
Republics, Slovenia, Croatia and Italy going into the log.

Amazingly I was able to technically work all continents over the 2
days on both 15 and 10 meters thanks to the multi-hop sporadic E!
P33W in Cyprus was logged on 40 to 10M for Asia, CN3A, Morocco (also
40 to 10M) and CR3DX, Madeira Is. for AF, WH7V on 10 (1853Z
Saturday, very rare) and several Hawaiians on 15 for OC, YW1K,
Venezuela (only SA on 10) for SA, and on 10 YT7Z, Serbia at 1442Z
Sunday along with HG3N Hungary, LZ8R Bulgaria, IB9T Sicily, and CR6K
Portugal for EU.

Each late afternoon Europe boomed in on 20 until past 2400Z
(Friday/Saturday).  At the end there was good sporadic E in almost
every direction.  Both Saturday and Sunday evening there was
essentially no skip zone on 40 vs. the usual one extending into NY,
New England, OH, and NC.  Europe was exceptional on 40M from
2400Z-0200Z Saturday evening with decently low static crashes.”

When Jeff mentioned “Benelux”, I had to look this up, and no, it
wasn’t a typo.  In fact, it has been around since 1944:

https://en.wikipedia.org/wiki/Benelux

Until I read this, I also had no idea that “Luxembourgish” is a
language.

On May 25, Ken Brown, N4SO of Alabama sent this report on recent 40
meter FT8 activity:

“40 Meters FT8 mode, power is 10 watts antenna is a Half Square.

234330 -17 -0.5 1189 ~ CQ YB3BBF OI72 Indonesia

Time represented is 2343 UTC and is before local sunset.

Very unusual time but that is Indonesia open with Caribbean, South
America, and Europe coming through all at the same time.

(Indonesia is very common early morning 1000, 1100, 1200 UTC)

Here is a sample of call signs: 9K2NO, ON4XM, EW8W, JA1EOD, JK7CWL,
YC8MJG with several other YB8/YC8 INDONESIA, 4E1FNS PHILIPPINES,
DS5USH REP. OF KOREA

I did not work Indonesia, Philippines, or Korea due to them working
the stronger Japanese stations, or others in the local area.”

Here is the best article I’ve ever read describing the solar cycle
prediction panel that met in Boulder in the first week in March, and
“best” includes any of the previous meetings.

https://bit.ly/2HMh21S

The writer makes a common error in confusing the daily sunspot
number with the number of sunspots, no doubt due to the arcane
method for arriving at the number.  She mentions 14 sunspots, but
the sunspot number on the day of the meeting was 14, meaning there
were four sunspots within a single group.  The sunspot number counts
10 points for each group, and one point each for the sunspots within
that group.

May 18 was the last day we saw sunspot activity, after more than two
weeks with daily sunspots visible.  Average daily sunspot number
declined to 5.3 this week following 22.7 during the previous week.
Average daily solar flux declined from 75.7 to 69.8.

Geomagnetic conditions were quieter, with average daily planetary A
index declining from 13 to 5.

Unsettled to active on May 28 and 29
Active to disturbed on June (11)

Solar wind will intensify on May 29 to 31, June 1, (10 to 12)

Parenthesis means lower probability of activity enhancement.”

On May 20, Markus Hansen, VE7CA wrote:

“Today I have been hearing many California beacons on 10 meters as
well as K7EMX/B in Utah.  So I have been calling CQ on 28005.00 for
several hours and not one single answer to my calls.

I have also been listening to AE6RQ’s SDR and my signal has been
between 579 and 20 over S 9 from 1700 to 2100Z.  I don’t have a 6
meter antenna up right now but wish I did.

I expect many have migrated to FT-8 etc.  Sad, being an old timer I
still love the sound of CW.

I appreciate your propagation reports.  I copy them regularly on CW
via W1AW.”

Max White, M0VNG sent this piece on Earth’s moving magnetic North
Pole:

https://bit.ly/2HC1j4e

Scott Avery, WA6LIE in Salinas, California reported a nice sporadic
E opening on 6 meters during Mother’s Day, May 12.

“We had a good opening from 1430-2030 UTC here in Salinas CM96.  Had
a lot of FT8 activity logging 45 contacts there and 6 QSOs on SSB.

Conditions were very wild for a bit on SSB with multiple QSO’s on
the same frequency ie:  50.130, 50.135 etc.  That lasted for about 2
hours after about 1600z.

Worked all I heard and worked many grid squares.  The MAGIC band…
got to luv it.”

K9LA recently updated a 2007 article he wrote for WorldRadio on
ionospheric sounders, which were referenced in recent bulletin
ARLP019.

The link to data from ionospheric sounders provided in ARLP019:

https://metrics.af7ti.com/

Note that you can re-order the table by clicking on any of the
headings.

For instance, at 0740 UTC on May 17 if I click on the foF2 column, I
can sort the ionosondes by foF2 values and discover that the
ionosonde on Cocos Island has the highest foF2 value, at 10.465 MHz.
Number 2 is Guam at 8.588 MHz, followed by Rome, Italy.

Later at 0850 UTC those values were 11.56 MHz, 8.6 MHz and 6.95 MHz.

Aloha All,

I see the Hakalau repeater is restored to the network.  Mahalo for the hard work.  The 3 repeaters are linked up.
Hilo 442.200 (+) PL 110.9
Pepeekeo  145.190 (-)  PL110.9
Hakalau 146.620 (-)  PL110.9
Laupahoehoe 442.550 (+) PL110.9
We have a simplex node in Kukuihaile AH6AE and we continue to look for someone willing to host a node in Pauuilo and/or Honoka’a area to cover the gaps.
73 and aloha

Sunspot activity continues, and this reporting week, the average
daily sunspot number rose from 16.1 to 22.7, while average daily
solar flux went from 73.5 to 75.7. The two sunspot groups that
appeared on May 3 and May 6 are fading fast and rotating off the
visible solar disc. Two geomagnetically active days occurred on May
11 and 14, when the planetary A index reached 25 and 36.

Predicted solar flux is 72 on May 16-18, 70 on May 19, 68 on May
20-22, 67 on May 23-29, 70, 72, 74, and 76 on May 30-June 2, 77 on
June 3-11, 75 on June 12, 72 on June 13-14, 70 on June 15, 69 on
June 16-17, 68 on June 18, 67 on June 19-25, and 70, 72, 74, and 76
on June 26-29.

Predicted planetary A index is 28, 20, and 8 on May 16-18, 5 on May
19-27, 10, 12, 8, and 10 on May 28-31, 5 on June 1-15, 8 on June 16,
5 on June 17-23, 10, 12, 8, and 10 on June 24-27, and 5 on June
28-29.

On May 10 Jeff, N8II in West Virginia reported a sporadic E opening
on 10 meters.

“Even a couple of QRP stations with small antenna were loud.
Starting around 1600-1900 UTC, I worked a mobile in South Carolina,
several in north Florida, Louisiana, a couple of Tennessee,
heard/worked all over Texas from Houston to Oklahoma border to west
Texas, Missouri, several Illinois, several Indiana, Wisconsin, two
Iowa, Nebraska,” he said.

“I also worked W2SDR in Salem County, New Jersey, apparently on Es
backscatter; when I turned antenna from west to New Jersey, his
signal did not improve (it was slightly weaker). All were 10-meter
SSB, most were S9 or better.”

Also on May 10, Jon, N0JK, reported 6 meter sporadic-E openings from
Kansas.

“Here in the Midwest, the band was open to W1, W2, W3, and W4. It
was probably the most widespread opening so far this season,” he
reported. “I worked AA2UK FM29 at 1908 UTC on 6 meters. Saw PV8DX
Brazil spotted to W1, W3, and W4.”

Sunspot numbers for May 9-15 were 25, 24, 26, 24, 23, 24, and 13,
with a mean of 22.7. The 10.7-centimeter flux was 76.2, 76.3, 78,
76, 74.7, 74.4, and 74, with a mean of 75.7. Estimated planetary A
indices were 7, 7, 25, 4, 6, 36, and 6, with a mean of 13. Middle
latitude A index was 8, 7, 19, 5, 5, 23, and 8, with a mean of 10.7.

We saw 0 sunspots from April 21 through May 2, but on May 3 sunspots
returned. Average daily sunspot number rose from 0 last week to 16.1
this week, and average daily solar flux increased as well, from 67.5
to 73.5.

Both the average middle latitude and planetary A index this week
were 6.6, and last week those numbers were 4.7 and 5.9 respectively.

Predicted solar flux is 75 on May 10-11, 73 on May 12-15, 74 and 76
on May 16-17, 72 on May 18-20, 68 on May 21-22, 67 on May 23-26,

2-13, 72 on June 14-16, 68 on June 17-18, 67 on June 19-22 and 69 on
June 23.

Predicted planetary A index is 5 on May 10, 14 and 12 on May 11-12,
5 on May 13-19, 8 on May 20, 5 on May 21-27, then 10, 12, 8 and 10

June 7-15, 8 on June 16, and 5 on June 17-23.

Geomagnetic activity forecast for the period May 10 to June 5, 2019
from F.K. Janda OK1HH.

“Geomagnetic field will be:
Quiet on May 10, 18-19, 22-23, 26-27
Quiet to unsettled on May 13-17, 21, 24-25, June 1-5
Quiet to active on May 11-12, 30
Unsettled to active on May 20, 28-29, 31
Active to disturbed-none

“Solar wind will intensify on May (10,) 11-12, 14, (20,) 21-23,
29-31, June 1.

“Parenthesis means lower probability of activity enhancement.”

Jeff, N8II in West Virginia wrote on May 4:

“We are in a bit of a funk waiting for sporadic-E to improve.

“Starting around 1900Z last Saturday and Sunday April 27-28, 20
meters began closing to north Florida in the FL QSO Party and was
completely closed by 2200Z. Then some sporadic-E appeared and 20 was
open to most of FL from around 2345Z-0145Z. On 40, there was no skip
zone, so the callers from everywhere drowned out the FL mobiles they
were calling.

“Due to the higher MUF, the mobiles were also weaker than normal on
40 Saturday evening, but fixed stations were still pretty loud.

Today, May 4, is the 7th call area QSO Party. 20 did not open well
until about 1415Z and signals were good until around 1700Z after
which they were much weaker and absolutely nothing was heard on 15,
worst ever 7th call area QSO Party conditions that I can remember.

“Most evenings around 2100-2300Z, 20 meters is wide open to southern
EU (many S9+ signals) despite the low SFI, but all DX signals are
pretty weak by 1300Z almost every morning.”

Steve Justus, W4SAJ lives in Central Florida and was on 10 meters
last Saturday (May 4) running FT8 mode at 100 watts and beaming
toward Australia with a 4 element mono-band beam. He was called by a
station in Beijing, and is curious about the possible propagation
mode, since Steve was not beaming in that direction. But FT8 is so
efficient with decoding weak signals that this contact does not
surprise me, although the signal strength may have surprised Steve.

Mike Schaeffer, KA3JAW in Easton, Pennsylvania wrote Thursday, May
9:

“This evening, while monitoring CB channel 29 (27.285 MHz) AM mode
between 0020-0203 UTC, May 10, while the MUF reached 74 MHz over
Maidenhead grid square EM53 (Starkville, MS), with the solar flux
being 76, the following state stations were heard: (AL, FL, GA, IL,
IN, KY, MN, NC, OH, TN, WV). 0020 UTC is 14 minutes after local
sunset, 8:06 pm EDT.

“According to NOAA solar wind prediction models, the Earth is going
to get slammed with a solar storm on May 11 at 1000 UTC. Expect
noisy propagation conditions on the high frequency bands.”

This just in, via WW1ME, VE7DXW and AF7TI:

Go to:

This shows you recent foF2 readings from Point Arguello in Southern
California.

foF2 is the highest frequency reflected vertically from the
ionosphere using an ionosonde.

Here is a list of ionosondes:

http://metrics.af7ti.com/

You can check data from other locations by plugging the station code
(such as BC840 for Boulder, Colorado) into the Point Arguello URL
(replacing PA836), like this:

I only know definitions of a few of the parameters listed, such as
foF2 and TEC (Total Electron Content).

I hope to have more info on these tools next week.
