ARLP007 Propagation de K7RA

Another week passed with no sunspots, and as of February 14 it has
been over two weeks since any sunspots were observed, the last on
January 30. February 7 through 13 saw average daily solar flux
decline from 71.1 to 70.4, compared to the previous seven days.
Geomagnetic indices were lower, with average daily planetary A index
declining from 11.6 to 8.1, and average mid-latitude A index going
from 8 to 6.1. Lower geomagnetic activity is generally good for HF
propagation.

Predicted solar flux over the next 45 days is 70 on February 15-21,
72 on February 22-25, 71 on February 26 through March 9, 70 and 71
on March 10-11, 72 on March 12-24, and 71 on March 25-31.

Predicted planetary A index is 12 and 8 on February 14-15, 5 on
February 16-18, then 12, 20, 12 and 8 on February 19-22, 5 on
February 23-26, then 12, 15, 15 and 10 on February 27 through March
2, 5 on March 3-4, then 8, 5, 8, 10, 8 and 5 on March 5-10, 8 on
March 11-12, 5 on March 13-17, then 12, 20, 12 and 8 on March 18-21,
5 on March 22-25, 12 on March 26, 15 on March 27-28, 10 and 5 on
March 29-30.

The prediction of solar flux always at 70 or above over the next 45
days is a positive sign for HF propagation, and also the Spring
Equinox returns on March 20, indicating gradually improving HF
propagation.

Geomagnetic activity forecast for the period February 15 until March
13, 2019 from F.K. Janda, OK1HH.

“Geomagnetic field will be:
Quiet on February 16-17, 24-26
Quiet to unsettled on February 18, 27, March 3-4, 6-7, 10-11
Quiet to active on February 15, 23, March 5, 8-9, 13
Unsettled to active on February 19, 22, March 1-2, 12
Active to disturbed on February 20 (- 21), 28

“Solar wind will intensify on February (19,) 20-21, (22, 28) March
(1-3, 6-9, 13). Parenthesis means lower probability of activity
enhancement.”

Jon Jones, N0JK writes to us from Lawrence, Kansas, where he
operates on 6 meters with a very modest antenna and low power.

“A set of rare off season 6 meter sporadic-E openings appeared on
the evening of February 7, and again the morning of February 8.

“February 7 sporadic-E appeared suddenly on 6 meters starting around
2300z from W2, W3 to W4, and W4 to W0.

“The next morning February 8, there was strong sporadic-E on 50 MHz
across the eastern United States and Canada. N0LL (EM09) worked
short Es (high MUF) to W4HLR (EM56) at 1450z. The opening finished
around 1845z with K9MU (EN44) working VE1JF (FN74).

“The only months with less sporadic-E than February in North America
are: March, September and October.”

69.9, 70.2, and 70.4, with a mean of 70.4. Estimated planetary A
indices were 4, 9, 10, 6, 9, 6, and 13, with a mean of 8.1.
Estimated mid-latitude A indices were 3, 7, 6, 4, 7, 5, and 11, with
