ARLP051 Propagation de KT7H
Solar activity was up very slightly last week when compared to the week previous. Solar flux below the average for the previous 90 days on every day through the week. Geomagnetic conditions have been stable, with the December 4 the most active day. K indices were as high as five and the A index was 16. Otherwise most days have had K indices of zero and one.
Conditions are expected to remain about the same, with solar flux in the low seventies and low geomagnetic activity. A recurring coronal hole is expected to cause a mild upset around December 26 and again around December 31, but the A index is expected to remain below 20 on both days.
Next week will be the last propagation bulletin for the year, because the author will be vacationing in Brazil until January 3.
Sunspot Numbers for November 30 through December 6 were 17, 16, 16, 23, 22, 22 and 15, with a mean of 18.7. 10.7 cm flux was 74.3, 72.7, 73.3, 73.3, 72.8, 73.6 and 74, with a mean of 73.4.
