Güneş Aktif Bölgeleri ve parlama

Solar flaring activity was low over the past 24 hours, with only C-class flares identified. A total of 11 numbered sunspot groups were identified on the visible side of the disk over the past 24 hours. All regions are magnetically simple, classified either as magnetic type alpha or beta. SIDC Sunspot Group 768 (NOAA Active Region 4351) and SIDC Sunspot Group 762 (NOAA Active Region 4342) have contributed to most of the low flaring activity over the past 24 hours. The strongest activity was a C8.8 flare (SIDC Flare 6745) with peak time 13:39 UTC on Jan 26, produced by SIDC Sunspot Group 774 (NOAA Active Region 4355), which has since exhibited some decay. The solar flaring activity is expected to be at low levels over the next 24 hours with likely C-class flares and 40% chances for M-class flaring.

Koronal Kütle Atılımı

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

Güneş rüzgarı

Over the past 24 hours the solar wind parameters (as measured by ACE at L1) have continued to register mild enhancements, possibly a waning connection to the positive polarity coronal hole (SIDC 146). The solar wind speed varied in between 549 km/s and 394 km/s. The magnitude of the interplanetary magnetic field (B) remained mildly elevated with a maximum value of 8.5 nT and a minimum north-south (Bz) component of - 6.5 nT. The B field phi angle was entirely in the positive sector (directed away from the Sun) possibly reflecting the polarity of the geo-effective CH 146. The solar wind conditions are expected to register a new high speed stream arrival over the next 24 hours related to the negative polarity coronal hole SIDC 147, which first crossed the central meridian on Jan 24.

Jeomanyetizma

The geomagnetic conditions over the past 24 hours were globally quiet to unsettled with several isolated active periods registered over Belgium between 21:00 and midnight UTC on Jan 26. The geomagnetic conditions are expected to register unsettled to minor storm levels within the next 24 hours with small chances for moderate storm levels to be reached due an anticipated high speed stream arrival.

Proton akı seviyeleri

Over the past 24 hours the greater than 10 MeV GOES proton flux was below the 10 pfu threshold and close to nominal levels. The greater than 10 MeV GOES proton flux is expected to be at nominal levels over the next days.

Jeostatik yörüngedeki elektron akıları

The greater than 2 MeV electron flux as measured by GOES 19 has exceeded the 1000 pfu threshold over most of the past 24 hours and is expected to exceed the 1000 pfu threshold again 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.
