Joint USAF/NOAA Report of Solar and Geophysical Activity

SDF Number 064 Issued at 2200Z on 05 Mar 2001

IA. Analysis of Solar Active Regions and Activity from 04-2100Z to 05-2100Z

Solar activity remained at low levels. Isolated B- and C-class X-ray bursts occurred. Minor growth was noted within Regions 9366 (S25E00), 9368 (N26E08), 9370 (N09E28), and newly numbered Region 9371 (N21W51). However, all regions remained simply structured.
IB. Solar Activity Forecast
Solar activity is expected to be low with a slight to fair chance for an isolated M-class flare.
IIA. Geophysical Activity Summary 04-2100Z to 05-2100Z
Activity ranged from quiet to minor storm levels. Active to (isolated) minor storm conditions occurred during the first half of the period due to recurrent coronal hole effects. Activity dropped to quiet to unsettled levels after 05/1200 UTC.
IIB. Geophysical Activity Forecast
Geomagnetic field activity is expected to be at quiet to active levels on 06 March as coronal hole effects continue. Quiet to unsettled levels are expected during the rest of the period. The greater than 2 MeV electron flux at geosynchronous orbit may reach high levels during the period.
