hr propagation forecast bulletin nr 45   from arrl headquarters
newington ct  november 5, 1984
to all radio amateurs  bt

during the last 5  days  of  october,  the  solar  flux  varied
between  69  and 73 , a range characteristic of months close to
the end of the 3 previous cycles for  which  flux  records  are
available.   despite  the low solar flux, the period was marked
by generally good propagation on 14 mhz and lower  frequencies.
21  mhz  was open over much of the world at times, but only for
short periods.  28 mhz was active mainly on north south and low
latitude circuits.

the solar flux rose after october 29, but  geomagnetic  indices
also  rose,  and  propagation  in the higher latitudes suffered
markedly.  conditions are expected to continue erratic  through
november  tenth,  becoming  more  stable  november  11 to 15th.
slightly higher flux readings should increase  activity  on  21
and  28  mhz  at  this  time.   degraded  conditions are likely
november 15 through 20.  for several days after about  november
21,  we  may have some of the best propagation of the autumn dx
season.  more on  this  possibility  will  be  given  in  later
bulletins.

american sunspot numbers for october 25 through november 2 were
between 0 and 9 with a mean of 3.6  ar
