Güneş Aktif Bölgeleri ve parlama

Solar flaring activity was high over the past 24 hours, with 2 M-class flares identified. The largest flare was an M5.0 flare (SIDC Flare 5902) peaking on November 03 at 10:11 UTC, which was produced by SIDC Sunspot Group 687 (NOAA Active Region 4274). A total of 6 numbered sunspot groups were identified on the disk over the past 24 hours. SIDC Sunspot Group 687 (NOAA Active Region 4274), which has rotated over the east limb on the Suns visible disk is the largest and most magnetically complex (Beta-Gamma) region 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.

Koronal Kütle Atılımı

A Coronal Mass Ejection (CME) seen in LASCO-C2 data around 05:24 UTC on November 03 and associated with SIDC Sunspot Group 687 is not expected to impact the Earth. A second CME also associated with SIDC Sunspot Group 687 was seen in LASCO-C2 data around 09:48 UTC on November 03. We are currently waiting for additional data to assess whether this second CME has an Earth directed component or not.

Koronal delikler

A recurring large coronal hole, SIDC Coronal Hole 116 (equatorial coronal hole with a negative polarity) first reached the central meridian on November 03. It’s associated high-speed stream is expected to arrive at Earth on November 06 (Other crossing times: October 08, September 10, August 15, July 20, June 22, May 26).

Güneş rüzgarı

Over the past 24 hours the solar wind conditions at Earth were under the waning influence of high-speed solar winds from SIDC Coronal Hole 123 (southern hemisphere, positive polarity) and 129 (northern hemisphere, positive polarity). The solar wind speed ranged from 430 km/s to 600 km/s. The total interplanetary magnetic field ranged from 6 to 9 nT, with the Bz reaching a minimum of -8 nT. Quite solar wind conditions are expected in the next 24 hours.

Jeomanyetizma

The geomagnetic conditions over the past 24 hours reached active conditions globally and locally (Kp 4 & K BEL 4). Active conditions are expected for the next 24 hours.

Proton akı seviyeleri

The greater than 10 MeV GOES proton flux was below the 10 pfu threshold level over the past 24 hours and is expected to remain so for the next 24 hours.

Jeostatik yörüngedeki elektron akıları

The greater than 2 MeV electron flux measured by GOES 18 and GOES 19 was above the 1000 pfu at the start of the reporting period. The greater than 2 MeV electron flux is expected to fluctuate around the 1000 pfu threshold over the next 24 hours. The 24-hour electron fluence was at moderate levels, it is expected to remain at moderate levels over the next 24 hours.
