2. FORECAST (02 MARCH - 08 MARCH)
Solar: Very low to low.

Geomagnetic: Possible minor storm periods late in UT day of
2 March, with minor storm periods expected for 3 March.
Mostly unsettled to quiet conditions for 4-5 March with
possible active to minor storm periods for 6-8 March due
to a coronal hole.

Frequencies: Degraded HF conditions possible for 3-4 March
and again for 6-8 March, otherwise mostly normal.

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.
