ARLP012 Propagation de KT7H

Solar activity remained very low last week.  Geomagnetic conditions
ranged from unsettled to active, with a few quiet periods.  The most
disturbed days were March 17 and 21 when the A index was above 20.
March 20 was the most stable day, with the A index at 8 and the K
index dropping all the way to zero during one period.

For the SSB WPX contest this weekend look for a slightly rising
solar flux, possibly reaching 100, with fairly stable geomagnetic
conditions.  20 meters should be the best all around band for
worldwide DX during the daylight hours and into the early evening.

Unfortunately, the short term rise in solar flux should reach a
maximum of only about 100 early in the week, and then drop back to
around 90 by April 5, when a recurring coronal hole is expected to
raise some havoc.  April 4 through 7 could be very disturbed, if
conditions from the last solar rotation four weeks earlier are any
guide.  After the drop in solar flux it should increase again to
around 105 by the middle of April.

Sunspot Numbers from March 17 through 23 were 30, 24, 11, 11, 26, 35
and 32, with a mean of 24.1.  10.7 cm flux was 85.1, 87, 89.1, 88.6,
90.7, 91.1 and 91.8, with a mean of 89.1.

The path projection for this week is from Sweetwater, Tennessee,
which is between Chattanooga and Knoxville, and United Arab
Emirates.

80 meters should be open from 0030 to 0230z, and 40 meters from 2330
to 0300.  30 meters looks good from 2300 to 0330, and 20 meters from
2000 to 0030, with the best time from 2230 to 2330.  17 meters
should be open from 1430 to 1930.  15 meters does not look very
promising, but check from 1700 to 1830.  12 and 10 meters do not
look good at this time, but there is a very slight chance of a 12
meter opening from 1600 to 1900, and on 10 meters around 1800 to
1830.
