Aktywne obszary słoneczne i rozbłyski

Solar flaring activity was low over the past 24 hours, with only C-class flares identified. A total of 12 numbered sunspot groups were identified on the visible solar disk over the past 24 hours. All regions are relatively small and remain magnetically simple (classified as magnetic type alpha or beta). The strongest flaring activity was a C1.7 flare (SIDC Flare 6760) with peak time 08:63 UTC on Jan 30, produced by SIDC Sunspot Group 781 (NOAA Active Region 4363) near the east limb. The solar flaring activity is expected to be low over the next 24 hours with very likely C-class flares and small chances for M-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) were under a waning influence of a high speed stream related to the negative polarity coronal hole (SIDC Coronal Hole 147). The solar wind speed was gradually decreasing with values varying in the range of 517 km/s to 781 km/s. The magnitude of the interplanetary magnetic field (B) has decreased reaching a maximum value of 6.2 nT with a minimum north-south (Bz) component of - 5.7 nT. The B field phi angle remained predominantly in the negative sector (directed towards the Sun) reflecting the polarity of the geo-effective SIDC Coronal Hole 147. The solar wind parameters are expected to follow a gradual trend towards nominal slow solar wind conditions over the next 24 hours and register nominal values thereafter.

Geomagnetyzm

The geomagnetic conditions over the past 24 hours have been quiet to active. Predominantly quiet to unsettled geomagnetic conditions are expected for the next 24 hours with chances for isolated active periods under the waning influence of a high speed stream. Mostly quiet conditions are expected thereafter.

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 next days.

Strumienie elektronów na orbicie geostacjonarnej

The greater than 2 MeV electron flux as measured by GOES 18 and GOES 19 was 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 24 hours. The 24-hour electron fluence was at moderate levels and is expected to increase towards the border of moderate to high levels over the next 24 hours. The 24-hour electron fluence is expected to remain at or above moderate levels over the next days.
