Re: Microwave...

Somewhat timely, this arrived in my mailbox this afternoon. For those
using satellites and HF, this could be an issue. Should not effect
terrestrial microwave though.

LARGE SUNSPOT GROUP POSES STORM THREAT THROUGH APRIL 5, 2001

A very large, complex sunspot group is currently crossing the face of
the 
Sun. This sunspot group, designated by NOAA space weather forecasters as 
Region 9393, has been growing at a rapid rate since rotating into view
on 
March 22. Forecasters expect Region 9393 to produce intermittent radio 
blackouts as high as the category R3 (strong) level before it rotates to
the 
backside of the Sun on April 5. This region also appears capable of
producing 
a category S1 (minor) to S2 (moderate) space radiation storm. Earlier
today, 
Region 9393 produced an R1 (minor) radio blackout followed by an 
Earth-directed coronal mass ejection (CME). This CME is expected to
cause 
category G1 (minor) to G2 (moderate) geomagnetic storm conditions on
March 30 
- 31.
