SOLAR SUMMARY Activity 05 Sep: Very low Flares: none. Observed 10.7 cm flux/Equivalent Sunspot Number for 05 Sep: 103/52 1B. SOLAR FORECAST 06 Sep 07 Sep 08 Sep Activity Low Low Low Fadeouts None expected None expected None expected 10.7cm/SSN 105/54 110/60 110/60 COMMENT: Some spot development between 04-20UT to north-east and south east of 667. Magnetic configuration of this region remains simple. Background xray flux only shows a small increase toward the end of UT day. This trend may continue if current spot development around 667 continues. 667 is currently quiet with no solar radio events observed on the Culgoora Radiospectrograph. Solar wind speed was steady until around 17UT afterwhich jumping to 360 km/sec. The north south component of the interplanetary magnetic field was southward 10nT 13-17UT. The origin of the small jump in the solar wind speed is unclear. US Space Environment Centre reported a filament eruption at N22W30 around 06UT. Subsequent viewing of LASCO C2 imagery (as C3 had stopped) showed a north-west directed bubble. The lack of subsequent images hampered decision on geoeffectiveness. But available imagery suggests that the CME bubble did not expand greatly and appeared directed mostly away from the Earth. This estimate may be revised as more images become available, as these would show any further expansion of the CME. Also, speculatively, recent far-sided halo mass ejections suggest that a possible active region may rotate onto the solar disk in 5-7 days time. |
