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. Bob 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.
