Solar flux and sunspot numbers continue their lull, although again
this week their relative positions see sawed. For last weeks
bulletin6, 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 bulletin. 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. Nothing significant about any of this, which is common
behavior as the solar cycle continues to decline. Geomagnetic
conditions have been nice and quiet, but this could change over the
next week. The predicted planetary A index 3 is 8, 8, 20, 40 and 15.
A planetary A index of 40 indicates a major geomagnetic storm, which
is expected from the reappearance of a recurring coronal hole and
associated high velocity wind stream. The predicted smoothed sunspot
number drops 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‚
