Solar flux and sunspot numbers continue their lull, although again
this week their relative positions see sawed. For last weeks
bulletin of April 22, or ARLP016, we reported average daily sunspot
numbers up a little, and average daily solar flux down a bit. This
change was noted when the numbers were compared to the data in the
April 15 bulletin, or ARLP015. This week the daily sunspot number on
average dropped 25 points to 25R9, and the average daily solar flux
increased a little over two points to 84. The predicted smoothed
sunspot number drops in May from 22 to 19. It will continue to
decline, with the predicted smoothed sunspot number at 10 for the
end of 2005 and 5 for the end of 2006, the predicted bottom of the
solar cycle. Sunspot numbers were 22, 34, 35, 0, 25, 20 and 45 with
a mean of 25R9. 10R7 cm flux was 77R1, 77R2, 79R3, 82R3, 86, 90R9
and 95R3, with a mean of 84. Estimated planetary A indices were 4,
9, 6, 10, 11, 5 and 4 with a mean of 7. Estimated mid latitude A
indices were 2, 7, 5, 5, 9, 2 and 1, with a mean of 4R4‚
