Güneş Aktif Bölgeleri ve parlama

Solar flaring activity was low over the past 24 hours, with only C-class flares identified. A total of 10 numbered sunspot groups were identified on the disk over the past 24 hours. Most active regions are magnetically relatively simple, classified either as magnetic type alpha or beta. SIDC Sunspot Group 772 (NOAA Active Region 4353) is the only region, classified as magnetic type beta-gamma, but has been stable and inactive. Most of the observed flaring activity is related to SIDC Sunspot Group 769 (NOAA Active Region 4349) and SIDC Sunspot Group 766 (NOAA Active Region 4345). The strongest activity was a C7.9 flare (SIDC Flare 6736) with peak time 21:43 UTC on Jan 25, produced by SIDC Sunspot Group 762 (NOAA Active Region 4342). SIDC Sunspot Group 774 (NOAA Active Region 4355) and SIDC Sunspot Group 768 (NOAA Active Region 4351) have exhibited some growth with the latter contributing to the low levels of flaring activity. The solar flaring activity is expected to be at low levels over the next 24 hours with likely C-class flares and close to 50% chances for M-class flaring.

Koronal Kütle Atılımı

No other Earth-directed coronal mass ejections (CMEs) have been identified in the available coronagraph imagery over the past 24 hours.

Koronal delikler

An equatorial negative polarity coronal hole (SIDC 147) which first crossed the central meridian on Jan 24 continues to partly reside there. A high speed stream emanating from it is expected to arrive at Earth late UTC on Jan 27 or Jan 28.

Güneş rüzgarı

Over the past 24 hours the solar wind parameters (as measured by ACE at L1) have continued to register a waning influence of a previously active high speed stream, mostly probably related to the positive polarity coronal hole (SIDC 146). The solar wind speed varied in between 600 km/s and 440 km/s. The magnitude of the interplanetary magnetic field (B) remained elevated with a maximum value of 8.9 nT and a minimum north-south (Bz) component of - 5.4 nT. The B field phi angle was predominantly in the positive sector (directed away from the Sun) reflecting the polarity of the geo-effective CH 146. The solar wind conditions are expected to continue to be decline towards background slow solar wind conditions over the next 24 hours. A new high speed stream arrival is anticipated for late UTC Jan 27 or Jan 28 related to the negative polarity coronal hole SIDC 147.

Jeomanyetizma

The geomagnetic conditions over the past 24 hours were globally quiet to unsettled with several isolated active periods registered over Belgium between 15:00 and 18:00 UTC on Jan 25. Predominantly quiet to unsettled geomagnetic conditions are expected for the next 24 hours with remaining chances for isolated active periods. Unsettled to minor storm levels are likely for late UTC Jan 27 and Jan 28 with the anticipated arrival of a new high speed stream.

Proton akı seviyeleri

Over the past 24 hours the greater than 10 MeV GOES proton flux was below the 10 pfu threshold and has continued its gradual decrease towards nominal levels. The greater than 10 MeV GOES proton flux is expected to be at nominal levels over the next 24 hours.

Jeostatik yörüngedeki elektron akıları

The greater than 2 MeV electron flux as measured by GOES 19 has exceeded the 1000 pfu threshold over the entire period of the past 24 hours and is expected to remain predominantly above the threshold over the next 24 hours. The 24-hour electron fluence was at moderate levels and is expected to remain so over the next 24 hours.
