ARLP020 Propagation de KT7H
 
Solar activity was up a bit last week, and there was even a period
when the geomagnetic activity was quiet.  Solar flux was higher by a
average of about 13 points compared to the previous week, and May 12
and 13 had some periods when the K index was as low as one.
 
Solar flux should very gradually decline over the next couple of
weeks, reaching a low around 75 at the end of the month when a
recurring coronal hole returns to view.  At that time conditions
will be very disturbed for at least a week.
 
Sunspot Numbers from May 12 through 18 were 45, 71, 67, 55, 58, 59
and 58, with a mean of 59.  10.7 cm flux was 87.4, 89.5, 90.2, 91.4,
91.4, 95 and 93.6, with a mean of 89.8.
 
The projection for this week is from the Hawaiian Islands to the
Mariana Islands.
 
80 meters looks good from 0830 to 1630z, with the peak period from
1100 to 1530.  Check 40 meters from 0700 to 1730, and 30 meters from
0600 to 1830.  20 meters should be open from around the clock,
except around 1800 to 1900.  The best period on 20 meters should be
from 0830 to 1600.  17 meters should be good from 2000 to 1200,
peaking toward the end of the period.  Check 15 meters from 2130 to
0830, and on some days until 1100.  12 meters should be open from
2230 to 0600, and 10 meters from 0000 to 0500.
