09 Nov 10 Nov 11 Nov Activity R1, chance of R2 R1, chance of R2 R1, chance of R2 Fadeouts Possible Possible Possible 10.7cm/SSN 125/78 125/78 120/72 COMMENT: Solar flare activity on UT day 08-Nov was at the R1 level due to three M-class flares all produced by Active Region (AR) 4566 (S07W05, beta-gamma-delta), the largest of which was an M1.7 at 08/0746UT. This region also produced numerous C-class flares over the UT day. There are currently four numbered sunspot regions visible on the solar disk. AR 4566 is the largest and most magnetically complex region on the disk and has exhibited some minor development in its trailer spots. This region continues to harbour multiple delta spots in its current configuration. AR 4568 (S09E16, beta) has shown spot growth over the 24-hour period. All other regions are either stable or in decay. Solar flare activity is expected to be at the R1 level over 09-11 Nov, with a chance of R2 due to the magnetic complexity and flare history of region 4566. S0 solar radiation storm conditions were observed on UT day 08-Nov and forecast to continue over 09-11 Nov. No Earth-directed coronal mass ejections (CMEs) have been observed. A filament eruption was observed, visible in H-alpha imagery at 08/0051UT centred near N39W25. No significant CME was observed in association with this event. The solar wind speed on UT day 08-Nov was mostly stable, ranging between 660 and 800 km/s, and is currently near 720 km/s. The peak total interplanetary magnetic field strength (IMF, Bt) was 11 nT and the north-south IMF component (Bz) ranged from -9 to +7 nT. The solar wind speed is expected to increase on 09-Nov as Earth enters the section of greatest latitudinal extent within the elongated equatorial coronal hole. The solar wind speed is expected to remain elevated on 10-Nov as these high-speed wind stream effects persist, then decrease on 11-Nov.
