Because of the holiday last week, the Propagation Forecast Bulletin
went out without the usual weekly data at the bottom. The data
appears at the end of this bulletin. Average daily sunspot numbers
rose over 27 points to 48R1. Average daily solar flux values were up
9 points. Geomagnetic indices were on the average lower. Daily solar
flux is expected to stay around 80 until December 5, when it is
expected to decline. The predicted planetary A index for the next
five days is 12, 10, 15, 20 and 20. This indicates recurring
geomagnetic disturbance, especially toward the end of this week.
Sunspot numbers were 62, 51, 52, 56, 45, 36 and 35 with a mean of
48R1. 10R7 cm flux was 100R5, 101R1, 102, 96R4, 94R7, 92R6, and
89R7, with a mean of 96R7. Estimated planetary A indices were 3, 4,
10, 7, 3, 6 and 8 with a mean of 5R9. Estimated mid latitude A
indices were 1, 2, 6, 5, 2, 3 and 12, with a mean of 4R4.
Geomagnetic indicators, the A and K index, have remained low.  This
is good for HF propagation and with low sunspot numbers lowering the
MUF, Maximum Usable Frequency, perfect for long range communication
on 160 and 80 meters. Average sunspot numbers in the six days since
the last bulletin were 50R3, nearly 30 points above the average
reported in the previous bulletin.  The daily solar flux went just
above 100 on November 17 to 19, the days when large sunspot 822 was
passing across the center of the visible solar disk, and exerting
maximum influence.
