Aktywne obszary słoneczne i rozbłyski

Solar flaring activity was low over the past 24 hours, with only C-class flares identified. A total of 13 numbered sunspot groups were identified on the visible solar disk over the past 24 hours. All regions are magnetically simple, classified either as magnetic type alpha or beta. Several new regions have been numbered, one in the north-east quadrant (SIDC Sunspot Group 782) and two rotating onto disk from the east limb (SIDC Sunspot Group 781 and SIDC Sunspot Group 783). All three appear simple and inactive. The strongest flaring activity over the past 24 hours was a C1.5 flare (SIDC Flare 6755) with peak time 12:47 UTC on Jan 28, possibly produced by SIDC Sunspot Group 766 (NOAA Active Region 4345) from behind the west limb. The solar flaring activity is expected to be at low levels 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 the influence of a high speed stream related to the negative polarity coronal hole (SIDC Coronal Hole 147). The solar wind speed has increased up to 770 km/s. The magnitude of the interplanetary magnetic field (B) was moderately elevated reaching a maximum value of 13.6 nT with a minimum north-south (Bz) component of -12.2 nT. The B field phi angle was predominantly in the negative sector (directed towards the Sun) reflecting the polarity of the geo-effective SIDC Coronal Hole 147. The solar wind conditions are expected to remain elevated over the next 24 hours under the influence of the ongoing high speed stream. Gradual return towards slow solar wind conditions is expected on Jan 31.

Geomagnetyzm

The geomagnetic conditions over the past 24 hours have varied between quiet to minor storm levels under the influence of an ongoing high speed stream. Predominantly quiet to active geomagnetic conditions are expected for the next 24 hours with chances for further isolated minor storms in case of prolonged periods with southward-directed interplanetary magnetic field. Quiet to unsettled condition with chances for isolated active periods are expected on Jan 30 and quiet to unsettled conditions are expected late UTC on Jan 30 or Jan 31.

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 has exceeded the 1000 pfu threshold for a prolonged period of time over the past 24 hours. The greater than 2 MeV electron flux is expected to exceed the 1000 pfu threshold again for prolonged periods of time over the next 24 hours. The 24-hour electron fluence was at moderate levels and is expected to remain so over the next days.
