We saw no sunspots during this reporting week, March 22 to 28. The
previous week had sunspots on only three days, with an average of
5.6.  Average daily solar flux receded from 69.3 to 68.2. Average
daily planetary A index dropped from 14.4 to 10.6, and average mid
latitude A index declined from 11.3 to 8.9.  Predicted solar flux is
70 on March 30 to April 15, 69 on April 16, 68 on April 17 to 29, 69
on April 30, then 70 on May 1 to 12 and 69 on May 13.  Predicted
planetary A index is 10 on March 30, 5 on March 31 to April 4, then
8 and 12 on April 5 and 6, 5 on April 7 to 9, then 8, 15 and 20 on
April 10 to 12, 15 on April 13 to 15, then 8, 5 and 5 on April 16 to
18, then 15, 1 and 15 on April 19 to 21, then 18, 10 and 5 on April
22 to 24, then 15, 12 and 8 on April 25 to 27, 5 on April 28 through
May 6, then 8, 15 and 20 on May 7 to 9, 15 on May 10 to 12 and 8 on
May 13.  F.K. Janda, OK1HH sent this geomagnetic activity forecast
for the period March 30 to April 24, 2018.  With regard to ongoing
changes, current forecasts are less reliable again.  Jon Jones, N0JK
sent this on March 26.  Remarkable propagation on both 6 and 10
meters despite a SFI of only 68.  On March 23, 6 meters opened
between North America and CE, LU.  Ken AC4TO in Florida worked
CE4WJK and CE2SV.  I saw a spot by K0TPP for CE2SV on 50.313 MHz. I
copied one decode from CE2SV about 2240z. Probably afternoon TEP for
AC4TO, possibly an Es link from the Midwest to TEP.  The geomagnetic
field was active with the Kp to 4.  Conditions were good in the CQ
WPX SSB on 10 meters March 24.  Central and South American stations
were loud to eastern Kansas around 1930z and put 15 stations in the
log with 5 watts and mobile 1/4 wave whip. Conditions not as good
Sunday, though YV1KK was 20 dB over S9 at 2000z. At 2114z CE7VPQ was
very loud on 10 and I was his contact number 480.  For more
information concerning radio propagation, see the ARRL Technical
Information Service web page.  A detailed explanation of numbers
used in this bulletin is also available on this site.  An archive of
past propagation bulletins is also available.  Monthly propagation
charts between four USA regions and twelve overseas locations can be
found on the ARRL/Propagation web page.  Find better information and
tutorials on propagation on the K9LA web site.  The multiple
websites mentioned in this bulletin can be found in teleprinter,
packet, and Internet versions of 2018 Propagation Forecast Bulletin
ARLP013.  Sunspot numbers were 0, 0, 0, 0, 0, 0, and 0, with a mean
of 0. 10.7 cm flux was 68.5, 68.1, 67.6, 68.3, 67.8, 68.3, and 68.6,
with a mean of 69.3. Estimated planetary A indices were 7, 17, 9,
17, 12, 9, and 3, with a mean of 14.4.  Estimated mid latitude A
indices were 6, 15, 7, 15, 10, 7, and 2, with a mean of 11.3.
