KN4LF Daily MF Radio Propagation Outlook #2004-003

We have seen only three small C class solar flares in the past nine days.
With a virtually spotless Sun we have also seen the daily solar flux fall
into the upper 80's range and the background x-ray solar flux fall into the
A range. This all adds up to some pretty good MF/160 meter propagation
conditions the past few days and the good conditions should last into the
weekend. However occasional unsettled to active geomagnetic conditions may
block, scatter or partially absorb signals on high latitude propagation
paths at times.

As I've monitored MF band conditions the past few nights I've observed some
of the strongest north to south, east-west and west-east received signal
strengths of this dismal DX season. I've also seen high angle local and
regional propagation disappear at frequencies as low as 1845 kc, as the
critical frequency has dropped that low.
