hr propagation forecast bulletin nr 43  from arrl headquarters
newington ct  october 22 1984
to all radio amateurs  bt

it would not have been front page news a few  months  ago,  but
substantial  sunspot  activity appearing on the eastern portion
of the sun october 15 and 16 was welcome, indeed.   for  a  few
days,  something  more  than north south dx was available on 28
mhz, for the first time since  last  spring,  and  21  mhz  was
active  almost  worldwide for several days.  then the flux fell
back to 74, and action on both bands tapered off.

as usually happens, the solar outburst was followed in two days
by  rising  geomagnetic  activity,  which  tended  to knock out
propagation in  the  higher  latitudes.   cconditions  for  the
forecast  week  are  likely  to  be no better than fair in this
respect, through the 23rd.  solar flux values are  expected  to
remain  in  the  low  seventies  through  about  the  28th, but
conditions will be improving after the  24th.   a  small  solar
flux  rise  is  likely  at  the  months end, with a move toward
higher muf through about november 2.  in general,  november  is
expected  to  bring slightly better conditions than october has
up to this bulletin issue date.

american sunspot numbers for october 11 through 17 were between
0 and 22 with a mean of 10.0.   ar
