ARLP032 Propagation de K7RA
A new sunspot group appeared only briefly this week, on August 7 and
8. It was sunspot 2747, from current cycle 24. Sunspot numbers on
Monday and Tuesday were 11 and 12.
Average daily solar flux shifted only slightly from last week, from
67 to 67.2. Average planetary A index, a geomagnetic indicator
aggregated from magnetometers around the world, more than doubled,
from 5 to 10.3. This was due to solar wind which raised the
planetary A index to 35 on Monday. Alaska's high latitude college A
index reached 61 on Monday and 24 on Tuesday.
Predicted solar flux is 68
