COMMENT: Depressions in MUFs and degradations in HF 
conditions were observed from 24 to 28 October due 
to coronal hole activity.

Predicted Monthly T index for October:  94
2. FORECAST (30 OCTOBER - 05 NOVEMBER) 
MUFS: depressed 5% to 10% from 3 to 5 November, otherwise
MUFs expected to be near normal. SWFs possible early in 
week. 
Propagation conditions: Normal-fair from 3 to 5 Novemeber, 
otherwise normal. 
T index:  110

3. OUTLOOK (06 NOVEMBER - 06 DECEMBER)
Degraded HF propagation conditions possible:
03-06 Nov,10-12 Nov, 20-Nov to 25-Nov.

PEASE NOTE:
At this time of the solar cycle, space weather conditions
are frequently determined by short timescale events, not
able to be forecasted a week in advance.
