2. FORECAST (18 MARCH - 20 MARCH)
Date   T index  Conditions       MUFs                              
18 Mar     0    Normal           0 to 5% below predicted monthly

COMMENT: Expect near or slightly below monthly predicted HF frequencies 
for the next day. The effect of a small coronal hole should commence 
in ~2 days, 19th March UT, with slightly increased geomagnetic 
activity which will likely raise ionisation and HF frequencies 
to near monthly predicted levels for a day or two. Nightime blanketing 
sporadic-E that obscured the F-layer was observed on the eastern 
seaboard.
