Päikese aktiivsed piirkonnad ja pursked

Solar flaring activity was low over the past 24 hours, with only C-class flares identified. The largest flare was a C6.9 flare (SIDC Flare 5975) peaking on November 07 at 15:51 UTC, which was produced by SIDC Sunspot Group 687 (NOAA Active Region 4274). A total of 9 numbered sunspot groups were identified on the disk over the past 24 hours. SIDC Sunspot Group 687 (NOAA Active Region 4274) is the largest region on disk, the most magnetically complex (Beta-Gamma-Delta) and produced most of the flaring activity in the last 24 hours. SIDC Sunspot Group 689 (NOAA Active Region 4276), SIDC Sunspot Group 690 (NOAA Active Region 4277) and SIDC Sunspot Group 691 (NOAA Active Region 4278) have Beta magnetic configuration and produced C-class flares in the last 24 hours. Solar flaring activity is expected to be moderate over the next 24 hours, with M-class flares very likely and a small chance for X-class flares.

Krooniaine massiline väljavool

A partial halo Coronal Mass Ejection (CME) (SIDC CME 597) was detected in SOHO/LASCO-C2 data around 12:48 UTC on November 07. This CME is likely associated with a C 3.1 flare (SIDC flare 5979) peaking on November 07 at 12:49 UTC, which was produced by SIDC Sunspot Group 687 (NOAA Active Region 4274). Analysis of this CME is ongoing.

Päikesetuul

Over the past 24 hours, the Earth was under the influence of one or more ICMEs. The solar wind speed ranged from 576 km/s to 800 km/s. The total interplanetary magnetic field ranged from 4 to 12 nT, with the Bz reaching a minimum of -9 nT. The phi-angle started the period in the positive sector (directed away from the Sun) until switching to the negative sector at 23:57 UT on November 07. In the next 24 hours, the solar wind conditions are expected to remain disturbed due to the possible arrival of a CME (SIDC CME 595) that left the Sun on November 05.

Geomagnetism

The geomagnetic conditions reached moderate storm conditions (Kp 6) globally and active conditions (K BEL 4) locally. Minor to moderate storm conditions are expected in the next 24 hours.

Prootoni voo tasemed

The greater than 10 MeV GOES proton flux was at background levels and is expected to remain at background levels over the next 24 hours.

Elektronivoog geostatsionaarsel orbiidil

The greater than 2 MeV electron flux, as measured by the GOES-18 and GOES-19 satellites, were below the 1000 pfu threshold in the last 24 hours. The 2 MeV electron flux is expected to remain below the threshold during the next 24 hour. The 24-hour electron fluence was at normal levels and is expected to remain at normal levels over the next 24 hours.
