COMMENT: IPS Preliminary HF Communications Warning 32 was issued 
on 30 October and is current for 31 Oct to 1 Nov. HF conditions 
have been mostly normal to enhanced with some isolated depressions 
due to slightly enhanced geomagnetic activity. HF conditions 
are expected to be variable during 31 October with some isolated 
depressions early in the UT day and possible enhancements later 
in the UT day followed by further depressions around dawn, pending 
the arrival time of an anticipated CME. Short wave fadeouts are 
still possible for 31 October with a small chance of isolated 
M-flares.
