Tad Cook, K7RA, Seattle, reports: The average daily sunspot number for the
reporting week of May 25-31 dropped from 31.7 to 15.6, compared to the previous
 7 days. There were no sunspots on May 30, but on May 31 sunspot region 2661
appeared, and the sunspot number was 11, which is the lowest non-zero sunspot
number possible, due to the arcane method for counting sunspots. The average
daily solar flux increased from 74.1 to 77.2.

The average planetary A index increased from 11 to 13.3, and the average
mid-latitude A index went from 11.7 to 10.6.

Predicted solar flux is 75, 76, and 77 on June 1-3; 78 on June 4-6; 75 on June
7-10; 78 on June 11; 80 on June 12-21; 75 on June 22-23; 72, 78, and 72 on June
 24-26; 70 on June 27-July 5; 75 on July 6-7; 78 on July 8, and 80 on July
9-15.

Predicted planetary A index is 5, 10, 14, 8, and 6 on June 1-5; 5 on June 6-9;
10 and 12 on June 10-11; 8 on June 12-13; 10, 12, 25, and 10 on June 14-17; 8
on June 18-19; 5 on June 20-24; 12 on June 25; 5 on June 26-July 6; 10 and 12
on July 7-8; 8 on July 9-10, and 10, 12, 25, 10, and 8 on July 11-15.

Looking ahead: The latest forecast for ARRL Field Day weekend, June 24-25, has
solar flux on June 23-25 at 75, 72, and 78, and predicted planetary A index at
5, 5, and 12.

On Sunday during the CQ World Wide WPX CW contest, a large geomagnetic
disturbance occurred. Planetary A index was 51, and the High-Latitude College A
 index (Fairbanks, Alaska) was 84. I received two reports of enhanced 10-meter
propagation on Sunday. N6GP in California sent a link to a video.

Sunspot numbers for May 25-31 were 19, 22, 21, 20, 16, 0, and 11, with a mean
of 15.6. The 10.7-centimeter flux was 76.1, 80.2, 81.9, 78.8, 75.8, 73.7, and
74.1, with a mean of 77.2. Estimated planetary A indices were 4, 3, 14, 51, 10,
 7, and 4, with a mean of 13.3. Estimated mid-latitude A indices were 4, 3, 14,
 32, 10, 6, and 5, with a mean of 10.6.

In Friday's bulletin, look for an updated forecast, reports from readers, and
more on the May 28 disturbance and enhancement. Send me your reports and
observations.
