Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 078 Issued at 2200Z on 19 Mar 2009

IA. Analysis of Solar Active Regions and Activity from 18/2100Z to 19/2100Z: Solar activity was very low. The solar disk remains spotless. No flares were observed.

IB. Solar Activity Forecast: Solar activity is expected to be very low.

IIA. Geophysical Activity Summary 18/2100Z to 19/2100Z: Geomagnetic field activity was at quiet levels. The greater than 2 MeV electron flux at geosynchronous orbit was at high levels early in the period.

IIB. Geophysical Activity Forecast: Geomagnetic field activity is expected to be quiet to unsettled thru days one and two (20-21 March), returning to quiet on day three (22 March).
