Report of Solar and Geophysical Activity SDF Number 183 Issued at 2200Z on 01 Jul 2012 IA. Analysis of Solar Active Regions and Activity from 30/2100Z to 01/2100Z: Solar activity was moderate. Region 1513 (N16E03) produced an M2/Sb at 01/1918Z. The region did not show any significant growth or decay during the period. Region 1515 (S17E17) continued to grow in areal coverage and is now 850 millionths. New Region 1517 (N19E26) was numbered overnight. IB. Solar Activity Forecast: Solar activity is expected to be moderate with isolated M-class flares likely for the next three days (02-04 July). IIA. Geophysical Activity Summary 30/2100Z to 01/2100Z: The geomagnetic field was unsettled to active during the past 24 hours due to coronal hole high speed stream (CH HSS) effects. Minor storm periods were observed at high latitudes along with an isolated major storm period from 01/0900-1200Z. Solar wind speeds were steady at approximately 650 km/s with a total field strength of 5 nT throughout the period. The greater than 2 MeV electron flux at geosynchronous orbit reached high levels during the period. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be quiet to unsettled with a chance for active storm periods on days one and two (02-03 July) due to continued CH HSS effects. Quiet to unsettled conditions are expected on day three (04 July) as effects from the CH HSS begin to wane.
