Aktywne obszary słoneczne i rozbłyski

Solar flaring activity has reached high levels over the past 24 hours, with 5 M-class flares identified. A total of 9 numbered sunspot groups were identified on the visible solar disk. SIDC Sunspot Group 784 (NOAA Active Region 4366) remains by far the most complex region, responsible for all recorded M-class flaring. It has exhibited further growth and remains classified as magnetic type beta-gamma-delta. The strongest activity it produced was an M6.6 flare (SIDC Flare 6792) with peak time 10:02 UTC on Feb 01. The remaining 8 regions have been magnetically simple (classified as magnetic type alpha or beta). Several regions have decayed, SIDC Sunspot Group 769 (NOAA Active Region 4349) has rotated over the west limb and a new region, SIDC Sunspot Group 786 (alpha), has rotated onto disc from behind the east limb. The solar flaring activity is expected to be at moderate to high levels over the next 24 hours with very likely M-class flares and increasing probability for X-class flaring.

Koronalny wyrzut masy

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

Wiatr słoneczny

Over the past 24 hours the solar wind parameters (as measured by ACE at L1) have returned to nominal slow solar wind conditions. The solar wind speed varied in the range of 325 km/s to 497 km/s. The interplanetary magnetic field (B) was weak with a maximum magnitude of 5.7 nT and a minimum north-south (Bz) component of - 4.6 nT. The B field phi angle remained predominantly in the negative sector (directed towards the Sun). The solar wind parameters are expected to reflect nominal slow solar wind conditions over the next 24 hours.

Geomagnetyzm

The geomagnetic conditions over the past 24 hours have been globally quiet. Quiet to unsettled conditions were observed locally over Belgium. Predominantly quiet geomagnetic conditions are expected for the next 24 hours.

Poziomy przepływu protonów

Over the past 24 hours the greater than 10 MeV GOES proton flux was at nominal levels and it is expected to remain so over the 24 hours. Some enhancements are possible in case of strong eruptive activity particularly related to SIDC Sunspot Group 784 (NOAA Active Region 4366).

Strumienie elektronów na orbicie geostacjonarnej

The greater than 2 MeV electron flux as measured by GOES 18 and GOES 19 was continuously exceeding the 1000 pfu threshold over the past 24 hours. The greater than 2 MeV electron flux is expected to remain above the 1000 pfu threshold for prolonged periods of time over the next days. The 24-hour electron fluence was at the border of moderate to high levels and is expected to remain so over the 24 hours.
