Average daily sunspot numbers sank nearly 50 points to 94.3 this
week, and the average daily solar flux was down over 16 points to
117.8.  Geomagnetic indices were quite high, due to a solar wind
stream.  Predicted solar flux for the near term is 105 on May 31
through June 1, 110 on June 2 to 5, then 105, 115, 125 and 130 on
June 6 to 9, 135 on June 10 and 11, 140 on June 12 and 13, then 135,
125, 135 and 130 on June 14 to 17, and 125 on June 18 to 20.  The
predicted planetary A index is 18 on May 31, 15 and 10 on June 1 and
2, 8 on June 3 and 4, 5 on June 5 to 10, then 8, 12, and 8 on June
11 to 13, and 5 on June 14 to 17.  OK1HH predicts the geomagnetic
field will be quiet to active on May 31, active to disturbed June 1,
quiet to active June 2, mostly quiet June 3, quiet to unsettled June
4, quiet June 5 to 7, mostly quiet June 8 and 9, quiet June 10,
quiet to unsettled June 11, quiet to active June 12 to 14, mostly
quiet June 15 to 17, quiet June 18, quiet to unsettled June 19 and
20, active to disturbed June 21, and quiet to active June 22.  The
Australian Space Forecast Centre issued an alert at 0524 UTC on May
30 warning of increased geomagnetic activity due to a solar wind
stream from a coronal hole. For May 31 they predict mostly unsettled
to active conditions with the chance of minor storm periods in the
latter half of the UTC day at high latitudes. For June 1 they expect
mostly unsettled conditions with a chance of active periods.  Rich
Zwirko, K1HTV of Amissville, Virginia wrote on May 29, Worked my
first European of the 2013 6M Es season at 2200Z yesterday, May
28th. Worked F8GGD and heard two other French stations on CW here at
my FM18ap Virginia QTH.  They were in and out of the noise here for
about 45 minutes before the band opened to the southeast. Worked
three stations in Venezuela as well as stations in J6, PJ4 and HI,
Dominican Republic, not Hawaii.  Did you know that in the past 9
years on 77 percent of the May 29 dates there was E Skip between the
Eastern USA and Europe, and 66 percent of the days on May 30th?
Check out this and other very interesting Es data from Kevin, VE3EN,
//www.solarham.net/6m/data.htm Lots of 6M ops in the Eastern U.S.
will have their beams on Europe today. The Es season has begun.
Sunspot numbers were 117, 99, 107, 92, 87, 75, and 83, with a mean
of 94.3. 10.7 cm flux was 134.5, 127.3, 121.3, 120, 110.1, 104.8,
and 106.9, with a mean of 117.8. Estimated planetary A indices were
7, 20, 32, 18, 13, 8, and 2, with a mean of 14.3. Estimated mid
latitude A indices were 8, 17, 25, 19, 8, 8, and 2, with a mean of
12.4.  The Amateur Radio Service has a longstanding secondary
allocation of 5.65 to 5.925 GHz, with an amateur satellite uplink
band at 5.65 to 5.67 GHz and a downlink at 5.83 to 5.85 GHz. In its
14 page filing, the ARRL traces the history of a continuing series
of overlays to which the band has been subjected over the past 16
years, progressively reducing the utility of the amateur allocation.
