Slunečně aktivní oblasti a vzplanutí

Solar flaring activity was moderate over the past 24 hours, with 1 M-class flare identified. The largest flare was an M1.7 flare (SIDC Flare 5971) peaking on November 07 at 07:16 UTC, which was produced by SIDC Sunspot Group 687 (NOAA Active Region 4274). A total of 7 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. Both SIDC Sunspot Group 687 (NOAA Active Region 4274) and SIDC Sunspot Group 689 (NOAA Active Region 4276) are the most magnetically complex (Beta-Gamma-Delta) regions on disk and produced most of the flaring activity 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.

Vyhazování koronální hmoty

A halo Coronal Mass Ejection (CME) (SIDC CME 596) was detected in SOHO/LASCO-C2 data around 07:36 UTC on November 07. This CME is associated with a M1.76 flare (SIDC flare 5971) peaking on November 07 at 14:00 UTC, which was produced by SIDC Sunspot Group 687 (NOAA Active Region 4274) and a type IV radio burst. Analysis of this CME is ongoing.

Solární bouře

Over the past 24 hours, the Earth was under the waning influence of an ICME and came under the influence of a second ICME associated with a CME (SIDC CME 593) that left the Sun on November 04. The solar wind speed started the reporting period around 530 km/s, gradually increased and then jumped from 665 km/s to 811 km/s at 04:50 UT on November 07. The total interplanetary magnetic started the reporting period around 6 nT, gradually increased and then jumped from 8 to 17 nT at the same time. The Bz component reaching a minimum of -16 nT in the last 24 hours. The phi-angle was mainly in the negative sector (directed towards the Sun), with periods in the positive sector. In the next 24 hours, the solar wind conditions are expected to remain disturbed due to the possible arrival of a CME (SIDC CME 594) that left the Sun on November 05.

Geomagnetismus

The geomagnetic conditions reached minor storm conditions (Kp 5) globally and active condtions (K BEL 4) locally. Moderate to major storm conditions are expected in the next 24 hours.

Úrovně protonového toku

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.

Elektronové toky na geostacionární oběžné dráze

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.
