Aktywne obszary słoneczne i rozbłyski

A total of 7 numbered sunspot groups were identified on the disk over the past 24 hours. Solar flaring activity was low over the past 24 hours, with only C-class flares identified. The largest flare was a C6.5 flare (SIDC Flare 3409) peaking on January 29 at 22:46 UTC, which was produced by SIDC Sunspot Group 388 (NOAA Active Region 3976). The two most magnetically complex regions on the solar disk are SIDC Sunspot Group 368 (NOAA Active Region 3977), which has a Beta-Gamma magnetic configuration and SIDC Sunspot Group 387 (NOAA Active Region 3974) which has a Beta-Delta magnetic configuration. SIDC Sunspot Group 388 (NOAA Active Region 3976) produced most of the flaring activity in the last 24 hours. SIDC Sunspot Group 389 (NOAA Active Region 3979) has emerged near the center of the solar disk. Solar flaring activity is expected to be high over the next 24 hours, with M-class flares very likely and a chance for X-class flares.

Koronalny wyrzut masy

No Earth-directed Coronal Mass Ejections (CMEs) have been detected in the available coronagraph images.

Returning SIDC Coronal Hole 82 (equatorial coronal hole with a positive polarity) and returning SIDC Coronal Hole 60 (mid-latitude coronal hole with a positive polarity) both started to cross the central meridian on January 28 and are continuing to cross the central meridian.

Wiatr słoneczny

Over the past 24 hours the Earth was under the slow solar wind regime. The solar wind speed ranged from 290 km/s to 366 km/s and the total interplanetary magnetic field ranged from 3 nT to 13 nT, with the Bz component reaching a minimum of -6 nT. The phi-angle was mainly in the positive sector (directed away from the Sun) with periods in the negative sector. The solar wind conditions are expected to become disturbed in the next 24 hours due to the anticipated high-speed-streams arrivals associated with two positive polarity coronal holes that started to cross the central meridian on January 28.

Geomagnetyzm

The geomagnetic conditions over the past 24 hours were globally quiet (Kp 1-2) and quiet to unsettled locally (K BEL 1-4). Active to minor storm 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 background levels and is expected to remain so over the next days.

The greater than 2 MeV electron flux, as measured by the GOES-16 and GOES-18 satellites remained below the threshold level in the last 24 hours. The electron flux is expected to remain below the threshold in the coming 24 hours. The 24h electron fluence is presently at normal level, and it is expected to remain so in the next 24 hours.
