Güneş Aktif Bölgeleri ve parlama

Solar flaring activity was low over the past 24 hours, with only C-class flares identified. SIDC Sunspot Group 652 (NOAA Active Region [AR] 4233, Alpha magnetic configuration) and SIDC Sunspot Group 653 (NOAA AR 4232, Beta magnetic configuration) produced two flares each. The brightest flare of the last 24 hours was SIDC flare 5689, a C5 on 7 Oct at 11:29 UTC, and is associated with SIDC Sunspot Group 657 (NOAA AR 4236, Beta-Gamma magnetic configuration). More C-class flaring activity is expected in the next 24 hours.

Koronal Kütle Atılımı

No Earth-directed Coronal Mass Ejections (CME) were observed in the last 24 hours.

Güneş rüzgarı

The Solar Wind (SW) conditions feature a slow SW regime during the past 24 hours. The SW speed ranged from 370 to 480 km/s, while the interplanetary magnetic field (B) varied between 4 and 10 nT, and its North-South component (Bz) fluctuated between -8 and 6 nT. A similar pattern is expected for the next 24 hours.

Jeomanyetizma

During the last 24 hours geomagnetic conditions were both globally and locally quiet to unsettled (NOAA Kp 2- to 3 and K BEL 2 to 3). They are expected to remain at the same level, both globally and locally, for the next 24 hours.

Proton akı seviyeleri

The greater than 10 MeV proton flux, as measured by the GOES-19 satellite, was at background levels over the past 24 hours and is likely to remain so in the next 24 hours.

Jeostatik yörüngedeki elektron akıları

The greater than 2 MeV electron flux as measured by GOES 19 was well above the 1000 pfu threshold during the past 24 hours, with a peak value at 16000 pfu. Although it features a gradual decline, it is expected to remain above the 1000 pfu threshold during the next 24 hours. The 24-hour electron fluence is at high levels since 4 Oct 23:10 UTC but also featured a gradual decline. It is expected to drop to moderate levels within the next 24 hours.
