SDF Number 213 Issued at 2200Z on 01 Aug 2010

IA.  Analysis of Solar Active Regions and Activity from  31/2100Z
to 01/2100Z:  Solar activity increased to low levels. Region 1092
(N13E21) produced a long-duration C3/Sf flare at 01/0826Z. The flare
was associated with a Type IV radio sweep, an 890 sfu Tenflare, and
an Earth-directed full-halo coronal mass ejection (CME). A
disappearing filament (DSF)  occurred during 01/0750 - 0811Z,
centered near N37W32 and time coincident with the C3 flare. The DSF
was associated with an Earth-directed partial-halo CME. No new
regions were assigned.
