Aktywne obszary słoneczne i rozbłyski

Solar flaring activity was low but frequent during the last 24 hours. NOAA Active Region (AR) 3561 (magnetic configuration Beta-Gamma, Catania sunspot group 45) produced almost all the activity, including the brightest flares, two C9. NOAA AR 3561 and 3559 (magnetic configuration Beta-Gamma, Catania sunspot group 43) are expected to continue producing C-class flares, while there is a change for an isolated M-class flare in the next 24 hours.

Koronalny wyrzut masy

No Earth directed Coronal Mass Ejections (CMEs) have been observed in the available coronagraph data.

Dziury koronalne

Two Coronal Holes (CH) with negative polarity started crossing the central solar meridian during the past 24 hours. The first crossing took place by a northern CH, possibly connected to the pole, and the second by southern hole close to the equator. A High Speed Stream (HSS) associated with these two CH is expected to affect the Earth's environment on Jan 29.

Wiatr słoneczny

The Solar Wind (SW) conditions of the last 24 hours were typical of the slow wind regime. A glancing blow from the passing of a Coronal Mass Ejection (CME) nearby only caused a very minor effect yesterday evening. The SW speed varied between 450 and 400 km/s, while the total interplanetary magnetic field (Bt) fluctuated between 4 and 10 nT and its North-South component varied between -7 and 6 nT. The interplanetary magnetic field phi angle was directed towards the Sun almost exclusively during the last 24 hours. The SW conditions are expected to be affected by another glancing blow in the next 24 hours.

Geomagnetyzm

Geomagnetic conditions were globally quiet (NOAA Kp 0+ to 2+), while locally they had a brief period of unsettled conditions (K BEL 0-3) during the last 24 hours. They are expected to continue at quiet levels in the next 24 hours and possibly rise to unsettled levels due to the expected arrival of a glancing blow from a Coronal Mass Ejection (CME).

Poziomy przepływu protonów

The greater than 10 MeV proton flux was at nominal levels over the past 24 hours and is expected to remain so for the next 24 hours.

Strumienie elektronów na orbicie geostacjonarnej

The greater than 2 MeV electron flux, as measured by the GOES-16 satellite, was well below the 1000 pfu alert threshold during the last 24 hours and is expected to to remain at this level during the next 24 hours. The 24h electron fluence was at low levels during the past 24 hours and is expected to remain at these levels for the following 24 hours.
