Aktywne obszary słoneczne i rozbłyski

Solar flaring activity was moderate with three M1 flares detected during the past 24 hours. NOAA Active Region (AR) 3744 (magnetic configuration Beta, Catania sunspot group no 96) produced the first two flares, an M1.5 at 20 Jul 18:49 UTC and an M1.4 at 21 Jul 03:55 UTC. NOAA AR 3751 (magnetic configuration Beta-Gamma-Delta, Catania sunspot group no 12) produced the third, an M1.5 at 21 Jul 08:34 UTC. Further M-class flaring activity is likely, mostly from the AR mentioned above, and there is a small chance of an X-class flare in the next 24 hours.

Koronalny wyrzut masy

No Earth-directed Coronal Mass Ejections (CME) were observed in the last 24 hours.

Wiatr słoneczny

Solar Wind (SW) conditions remained typical of the slow SW regime during the past 24 hours. The SW speed varied between 310 and 380 km/s, while the total interplanetary magnetic field (Bt) ranged between 2 and 10 nT during the past 24 hours. The North-South magnetic component (Bz) fluctuated between -4 and 6 nT, while the interplanetary magnetic field phi angle was directed predominately towards the Sun in the past 24 hours. The SW conditions are expected to follow the same pattern for the next 24 hours.

Geomagnetyzm

During the last 24 hours geomagnetic conditions were globally quiet (NOAA Kp 1 to 2+), while locally they had a brief period of unsettled conditions (K BEL 3 at 20 Jul 15:00-21:00 UTC). They are expected to remain quiet both globally and locally in the next 24 hours.

Poziomy przepływu protonów

The greater than 10 MeV proton flux was at nominal levels over the past 24 hours and is likely to remain so. Nevertheless, there is a small chance of a proton event associated with the activity of NOAA active region 3751.

Strumienie elektronów na orbicie geostacjonarnej

The greater than 2 MeV electron flux, as measured by the GOES-16 satellite, was at nominal levels during the last 24 hours and is expected to remain at these levels during the next 24 hours. The 24h electron fluence was at very low levels during the past 24 hours and is expected to remain at these levels for the following 24 hours.
