Topband: Propagation following X-ray increase

[Red Haines]

IPS reports a slightly higher critical frequency of the F2 layer at this 
location in SE MN today and I hear slightly stronger signals from the 20 
meter and 15 meter DX beacons at 1640z.  I hear nothing from the 10 
meter beacons.  NOAA is not predicting D layer absorption, which would 
affect 160 and 80 meter propagation.  I assume there is a normal level 
of D layer absorption and that the NOAA prediction intends to predict 
more absorption than is usual for daytime conditions.

Your observations on the low bands from last night and tonight will be 
welcomed.
