active areas of the sun that were responsible for the solar flux rise
in early october are facing the earth again. sunspot counts are far
below those of four weeks ago, and the solar flux high for november
is only 107 thus far.  at the same sun position in october the flux
was 134 and rising.  some further rise is expected in the next few
days, but anything approaching the october high of 140 now seems
unlikely.

november is traditionally a month of high muf and generally good
conditions on all dx frequencies, however, and prospects look good
for november 6 through 9, 16, 17, and 22 to 24.  fairly severe
disturbances and possible auroral conditions in northern u.s. and
adjacent canadian areas are expected november 10 through 15, 18 to 21
and 25 to 30.

american sunspot numbers for october 27 through november 2 were
between 1 and 20 with a mean of 11.4  ar
