Conditions were fairly good until May 1, when the previously
predicted cycle of disturbances from a coronal hole began again.
Solar flux was down a bit relative to the previous week.
 
Poor conditions should continue until the middle of May, when
geomagnetic activity should finally quiet down again.  Solar flux
will be rising until a peak around May 19 near 100.  Flux should
decrease again, with disturbances returning by the end of the month
for another cycle of high K indices.
 
Sunspot Numbers from April 28 through May 4 were 35, 16, 38, 80, 75,
52 and 38, with a mean of 47.7.  10.7 cm flux was 77.3, 77.8, 74.9,
75.2, 75.9, 74.4 and 73.1, with a mean of 75.5.
 
The projection for this week is from Larsen Bay, Alaska, on Kodiak
Island, to New Zealand.
 
80 meters should be open from 0700z to 1500z, and 40 meters from
0630z to 1530z.  Check 30 meters from 0530z to 1600z, and 20 meters
from 0430z to 0700z.  17 meters should be open from 0300z to 0430z,
and on same days as late as 0600z.  10, 12 and 15 meters do not look
good at this time.  All of this assumes that geomagnetic conditions
are not terribly stormy, which tends to create problems for
propagation in the higher latitudes.
