COMMENT: IPS HF Communications Warning 42 was issued on 30 October 
and is current for interval 2-3 November. Depressed MUF forecast 
slipped one day out as no shocks from recent coronal mass ejections 
have arrived yet. Initially normal to good HF conditions are 
now expected for today. Solar coronal mass ejections remain expected 
to cause degraded conditions late 02-03 Nov for southern Aus/NZ 
region only.
