hr propagation forecast bulletin nr 6    from arrl headquarters
newington ct  february 10, 1985
to all radio amateurs  bt

thus far in the month of february the solar flux has been 2  to
6  points higher than it was one solar rotation ago.  the trend
to higher solar flux and sunspot numbers began in the middle of
january.   the  author  of these bulletins expects the trend to
continue through about february 14, keeping  the  muf  slightly
higher than it was in early january.

the earths magnetic field was active for several days prior  to
bulletin time.  conditions were becoming more favorable in this
respect,  making  for  more  stable  propagation  on   all   dx
frequencies  except  28  mhz,  where  still  little  more  than
marginal north south dx can be expected.

the propagation charts in  qst  will  continue  to  be  on  the
optimistic  side,  as  they are based on much higher solar flux
and sunspot numbers than we are likely to see for some time.

american sunspot numbers for january  31  to  february  6  were
between 25 and 9 with a mean of 18.1  ar
