Conditions are pretty rotten right now, with no visible sunspots and
geomagnetic conditions active.  There were sunspots visible only two
days last week, and the solar flux has been down near the minimum.
 
Solar flux should rise slowly, peaking for the short term near 95
around May 23 and 24.  It should then drop quickly back toward the
current level.  Unsettled to active geomagnetic conditions are
expected for the next few days, and again around May 21, although
probably not as severe.
 
Sunspot Numbers for April 27 through May 3 were 0, 0, 12, 0, 12, 0
and 0, with a mean of 3.4.  10.7 cm flux was 68.2, 67.7, 68, 67.2,
68.6, 68.8 and 69, with a mean of 68.2.
 
This week's path projection is to Argentina from the middle of the
continental United States.
 
80 meters should be open from 0130 to 1030z, and 40 meters from 0030
to 1100.  Check 30 meters from 2330 to 0800, and 20 meters from 1100
to 1400 and again from 2100 to 0700.  17 meters should be open
around 1330 to 1600 most days, and again from 1830 to 0500.  On most
days 15 meters should be open from 1800 to 0230.
