We observed a return of sunspot activity during the past reporting
week (September 6-12), with spots on four days, but not consecutive.
Sunspots were visible on September 8-9 and 11-12. Average daily
sunspot numbers increased to 7.6, compared to zero over the previous
seven days.

Average daily solar flux increased from 67.8 to 68.6, and planetary
A index doubled from 6.3 to 12.6, while mid-latitude A index went
from 5.9 to 10.

The September 13 forecast predicted solar flux at 70 on September
14, 68 on September 15-22, 67 on September 23-24, 68 on September 25
through October 6, 70 on October 7-9, 68 on October 10-19, 67 on
October 20-21, 68 on October 22-28.

The same forecast over the same period supposes planetary A index at
8 on September 14-15, 10 and 8 on September 16-17, 5 on September
18-21, 12 and 8 on September 22-23, 5 on September 24-30, then 8 and
10 on October 1-2. 5 on October 3-6, then 12, 35, 15, 12, 12, 8, 5,
10 and 8 on October 7-15, 5 on October 16-18, then 12 and 8 on
October 19-20, 5 on October 21-27 and 8 on October 28.

As recently as September 9, the US Air Force predicted a rise of
solar flux to 75 on September 17 before dropping below 70, followed
by flux values of 70 on October 7-9. The day before, on September 8
the forecast showed flux values of 70 through September 16, 75 on
September 17, and 72 on September 18-22. Predicted solar flux was 75
for October 10-14. This was considerably more optimistic than the
latest forecast.

From OK1HH:

"Geomagnetic activity forecast for the period September 14 to
October 10, 2018

"Geomagnetic field will be:

"Quiet on September 17, 19
Quiet to unsettled on September 18, 20, 24, October 3
Quiet to active on September 14-15, 25-30, October 4-6, 10
Unsettled to active on September 16, 23, October 1-2, 9
Active to disturbed on September (21) -22, October 7-8

"Solar wind will intensify on September 14-16, (21,) 22-24, (25), 29.
October 1-2, 6-9

"Remarks:
- Parenthesis means lower probability of activity enhancement.

The latest from Dr. Tamitha Skov, WX6SWW on September 11.

"Dear Tad:

"My newest 'forecast shortie' came out on You Tube today as we were
passing the peak of this solar storm. As I feared (and mentioned on
Twitter and on Patreon numerous times), we did reach G2-level storm
conditions. In fact we remained at G2-levels for over 6 hours. This
meant emergency communication over the amateur radio bands was
non-existent. Luckily, it looks like the worst is now over. This is
good news as several 'hurricane watch nets' are activating as early
as tomorrow in anticipation of Hurricane Florence. However, the bad
news is the fast solar wind is ongoing and it will take several days
yet for the radio bands to fully recover. Let's hope they do before
this Category 4 storm makes landfall.

"Since becoming an amateur radio operator myself this Summer (my
call sign is now WX6SWW), I have really begun to appreciate the
extent that Space Weather thwarts emergency responders during
hurricane season. Even though I do not live on a coast threatened by
hurricanes-- Los Angeles hardly gets any rain at all, let alone a
hurricane-class storm-- like many, I am beginning to dread this time
of year. The concern worsens when I read articles published in
reputable weather journals that talk about the intensification of
hurricanes in the coming years. For all of our sakes, I hope that
climate scientists determine a 'Category 6' for hurricanes is not
warranted. Until then, articles like this one will continue to make
me very nervous. It really makes me wonder what the peak of the
hurricane season will be like in a few years when solar activity
begins to rise.

"Again, a huge debt of gratitude goes to the Patreon members, who
are making these 'forecast shorties' possible. Frequent forecast
updates such as these prove so critical at times like now. Thank you
for helping to keep communities aware so they can stay safe. You are
my heroes."

Editor:  Richard (G4TUT)

Before we get to the updated Amateur/Ham Radio news from the Southgate Amateur Radio Club, I would like to thank Hawaii radio amateurs for standing by during the passing of Hurricane Oliva, which has been downgraded to a weak tropical storm as it passes over the islands of Maui and Lanai.  Olivia left a path of high winds, heavy showers, and flooding before falling apart late Wednesday afternoon.  Our “aloha” and prayers also go to those in the path of Hurricane Florence which is battering the Carolinas.  RACES and ARES teams are ready to help emergency management personnel, county, and state officials should the need arise.

Here are today’s top Amateur/Ham Radio news stories from the UK-based Southgate Amateur Radio Club.  Views expressed in this news summary are those of the reporters and correspondents.

Moon bounce on a dipole
On Saturday the 8th of September, the Essex Dx Group achieved a world first by making a moon bounce EME contact using nothing more than a dipole

AMSAT Vice-President of Operations, Drew Glasbrenner, KO4MA says that the camera on AO-92 is planned to be used to try to image Hurricane Florence during North American east coast passes on Thursday, September 13, and Friday, September 14

EI8JK works Japan on 70cms Moonbounce for an EI first
Working Japan on any band from Ireland is pretty good but what about doing it on 432 MHz? That’s exactly what Tony EI8JK did on Monday the 10th of September 2018 when he worked Toshia JA6AHB by bouncing 70 cms signals off the moon!

NewsWest Special – Club activities around Australia
NewsWest is the VK6 news which has been produced since 1931.

DISCUSSION AND OUTLOOK
----------------------
At 500 PM HST (0300 UTC), the center of Tropical Storm Olivia was
located near latitude 20.9 North, longitude 154.2 West. Olivia is
moving toward the west near 15 mph (24 km/h). A general west-
southwest motion with a slower forward speed is expected this
evening as the center of Olivia approaches Maui and the Big Island.
After Olivia moves past the islands, a somewhat faster west-
southwest motion is expected to resume amd continue for the
next couple of days.
 
Maximum sustained winds are near 50 mph (85 km/h) with higher gusts.
Gradual weakening is forecast during the next 48 hours, but Olivia
is expected to remain a tropical storm as it moves over the main
Hawaiian Islands.
 
Tropical-storm-force winds extend outward up to 105 miles (165 km),
mainly to the north of the center.
 
The estimated minimum central pressure is 1003 mb (29.62 inches).
 
 
HAZARDS AFFECTING LAND
----------------------
WIND: Tropical storm conditions are expected over portions of
Maui County and the Big Island starting this evening. Tropical
storm conditions are expected over Oahu starting tonight. Tropical
storm conditions are expected over Kauai County starting Wednesday.
Remember that wind gusts can be much stronger near higher terrain,
particularly through gaps between mountains and where winds blow
downslope.
 
RAINFALL: Showers will continue to increase over portions of the
main Hawaiian Islands tonight and Wednesday. Olivia is expected to
produce total rainfall accumulations of 5 to 10 inches in some
areas, with isolated maximum amounts of 15 inches possible,
especially in higher terrain. This rainfall may produce
life-threatening flash flooding.
 
SURF: Large swells generated by Olivia will impact the main Hawaiian
Islands over the next couple of days. This will result in
dangerously high and potentially damaging surf, mainly along
exposed east facing shores.
 
 
NEXT ADVISORY
-------------
Next intermediate advisory at 800 PM HST.
Next complete advisory at 1100 PM HST.

As of 1800 HST, gusty winds and light rain 
have started in Laupahoehoe along the Hamakua
Coast.  Olivia is moving toward the island of
Maui where strong winds and heavy showers are
expected. Stay safe.
------------------
Once Tropical Storm Olivia leaves the state we 
can focus on a fun contest activity that should
help us forget recent storms and bad weather.
The Fifth Annual Hawaiian Grid Madness is coming
on Sunday, 16 September 2018, from 1300 to 1700
HST.  The Aulani Hui Amateur Repeater Club sponsors
