Candidates for the award must be 18 or younger and reside in the US (or its
possessions) or Canada. Nominees must hold a valid Amateur Radio license issued
 by the US or Canada. A candidate needs to have accomplished something
outstanding as an Amateur Radio operator, whether by recruiting new hams,
engaging in a community service project, or helping to benefit Amateur Radio in
 other ways. The award presentation will be held at the Huntsville Hamfest on
August 19, 2017. The Young Ham of the Year Award was created by Amateur Radio
Newsline founder Bill Pasternak, WA6ITF (SK). The 2016 YHOTY was Skyler
Fennell, KD0WHB, of Denver.



The K7RA Solar Update

Tad Cook, K7RA, Seattle, reports: Spaceweather.com reported that old sunspot
AR2644, which returned after a 2-week trip around the sun, exploded on April
18. The resulting coronal mass ejection (CME) should miss Earth, but as this
active region moves into a geo-effective position, we could see some
geomagnetic disturbance in the next few days.

Average daily sunspot numbers declined from 16.6 last week to 8.6 over the
April 13-19 reporting week. Average daily solar flux increased from 73.8 to
76.5.

Geomagnetic indicators were lower this week. The average planetary A index
declined from 10.6 to 8, while the average mid-latitude A index was 6.3, down
from 9.3 during the previous 7 days.

Predicted solar flux is 85 on April 20-27; 80 on April 28-May 1; 75 on May
2-13; 83 and 88 on May 14-15; 90 on May 16-18; 85 on May 19-24; 80 on May
25-28, and 75 on May 29-June 3.

Predicted planetary A index is 15 on April 20; 8 on April 21-22; 40 and 30 on
April 23-24; 20 on April 25-26; 30, 15, 10, 5, and 20 on April 27-May 1; 10 on
May 2-4; 15 on May 5-6; 5 and 8 on May 7-8; 5 on May 9-13; 20 on May 14; 15 on
May 15-16; 10 on May 17; 5 on May 18-19; 35, 25, 18, 20, and 25 on May 20-24;
12, 8, 5, and 18 on May 25-28, and 10 on May 29-30.

Sunspot numbers for April 13-19 were 12, 11, 11, 0, 0, 12, and 14, with a mean
of 8.6. The 10.7-centimeter flux was 73.5, 72.9, 73, 74.5, 75.2, 85.6, and
80.9, with a mean of 76.5. Estimated planetary A indices were 5, 14, 7, 4, 4,
7, and 15, with a mean of 8. Estimated mid-latitude A indices were 4, 10, 5, 4,
 3, 6, and 12, with a mean of 6.3.
