Here is the latest solar report. In case you missed it ...the bands still SUCK! It kinda reminds me of the weather report from Good Morning Viet Nam....Hot and shitty followed by more hot and shitty... It is supposed to be better for Field Day...Big whoop....Amateurs getting in the way of DXers....Best Advise is that in these conditions openings come and go....you have to have the radios on or you will miss thewm...Good Luck DX hunting!
Tad Cook, K7RA, Seattle, reports: The Australian Space Forecast Centre
on May 23 issued a geomagnetic disturbance warning for May 26-27,
starting with a minor to major storm warning for May 26, and a minor
storm on May 27. These are due to what’s called a “partial halo coronal
mass ejection.”
Average daily sunspot number for the May 18-24 reporting week increased
from 3.4 to 31.7. The previous week had 5 days of zero sunspots. There
were no zero-sunspot days this week, so the average daily sunspot number
is much higher now.
Over the same 2 weeks, average daily solar flux rose from 70.5 to 74.1.
Average daily planetary A index rose from 8.3 to 11, and average
mid-latitude A index rose from 9.4 to 11.7.
Predicted solar flux is 78 on May 25-28; 75 on May 29-June 1; 72 on June
2-3; 70 on June 4-8; 72 on June 9-11; 74 on June 12-18; 76 on June
19-23; 74 on June 24-25 (Field Day weekend); 72 on June 26-30, and 70 on
July 1-5.
Predicted planetary A index is 5 on May 25; 12 on May 26-27; 10 and 8 on
May 28-29; 5 on May 30-June 9; 10 and 12 on June 10-11; 5 on June
12-13; 8, 10, and 20 on June 14-16; 12 on June 17-18; 8 on June 19, and 5
on June 20-July 6.
ARRL Field Day is just four weeks away! The 45-day predictions
for solar flux and planetary A index look good for Field Day weekend.
For June 23-25, the predicted planetary A index is 5 (good) and solar
flux is 76 on Friday and 74 on Saturday and Sunday (not bad).
Sunspot numbers for May 18 through 24, were 24, 24, 22, 35, 55, 47, and
15, with a mean of 31.7. The 10.7-centimeter flux was 72.2, 72.3, 72.4,
73.5, 74.4, 76, and 77.9, with a mean of 74.1. Estimated planetary A
indices were 11, 11, 24, 9, 10, 8, and 4, with a mean of 11. Estimated
mid-latitude A indices were 15, 13, 23, 10, 9, 8, and 4, with a mean of
11.7.
