Sunspot numbers and solar flux rose again this week, while
geomagnetic indices were relatively quiet. Average daily sunspot
numbers rose from 108.1 in the first week of 2015 to 112.6 in the
following seven days. Average daily solar flux rose from 144.7 to
151.3.  Predicted solar flux for the near term is 130 on January 16,
125 on January 17 and 18, 120 on January 19 and 20, 115 on January
21 and 22, 140 on January 23, 130 on January 24 to 26, 135 on
January 27 and 28, 140 on January 29 and 30, and 145 on January 31
through February 7. Flux values then peak at 180 on February 11 and
12, and dip down to 130 on February 20 to 22.  Predicted planetary A
index is 12, 10, 15, 12 and 10 on January 16 to 20, 8 on January 21
and 22, then 5, 10 and 18 on January 23 to 25, and 15, 8, 5, 10 and
12 on January 26 to 30, 15 on January 31 through February 1, 12, 15
and 12 on February 2 to 4, 5 on February 5 and 6 and 10 on February
7 and 8.  OK1HH sent his predictions for geomagnetic conditions, and
believes there will be quiet to unsettled conditions January 16,
mostly quiet January 17, quiet to active January 18, quiet January
19, active to disturbed January 20, quiet to active January 21,
active to disturbed January 22, mostly quiet January 23, active to
disturbed January 24, quiet to active January 25, disturbed January
26, mostly quiet January 27, quiet January 28, active to disturbed
January 29 through February 1, quiet to active February 2 and 3,
mostly quiet February 4, quiet February 5, quiet to active February
6 and 7, and quiet on February 8 to 11.  The changes are, on
November 14, 2014 they said the smoothed sunspot number was 70 in
late 2013, and now on January 14, 2015 that has been revised upward
to 72. The new report says the smoothed sunspot number peaked at
81.9 in April 2014. This was the second peak for Cycle 24, the first
being 66.9 in February 2012. They noted that double peaked sunspot
cycles are common, but the current cycle is the first in which the
second peak was higher than the first.  This is the smallest sunspot
cycle since Cycle 14, which peaked at 64.2 in February 1906.  For
more information concerning radio propagation, see the ARRL
Technical Information Service web page.  A detailed explanation of
the 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 W1AW web site.  Find more good
information and tutorials on propagation on the k9la web site.
Sunspot numbers were 101, 125, 146, 133, 111, 93, and 89, with a
mean of 112.6. 10.7 cm flux was 157.2, 151.2, 151.9, 153.7, 158.6,
145, and 141.8, with a mean of 151.3.  Estimated planetary A indices
were 16, 8, 10, 10, 8, 8, and 7, with a mean of 9.6. Estimated mid
latitude A indices were 15, 7, 9, 8, 7, 5, and 5, with a mean of 8.
