Aktywne obszary słoneczne i rozbłyski

Solar flaring activity was moderate during the past 24 hours, with an M3.2 flare emitted from NOAA Active Region (AR) 3753 (magnetic configuration Beta, Catania sunspot group no 8) at 19 Jul 08:23 UTC. NOAA AR 3751 (magnetic configuration Beta-Gamma-Delta, Catania sunspot group no 12) produced most of the C-class flaring activity, including the second brightest flare, a C6 at 18 Jul 15:49 UTC. In the next 24 hours isolated M-class flare(s) are still likely to occur with a small chance of an X-class flare.

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 280 and 360 km/s, while the total interplanetary magnetic field (Bt) ranged between 2 and 6 nT during the past 24 hours. The North-South magnetic component (Bz) fluctuated between -4 and 4 nT, while the interplanetary magnetic field phi angle was directed predominantly away from the Sun in the past 24 hours. The SW conditions are expected to follow the slow SW 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 two three-hour periods of unsettled conditions (K BEL 3 at 18 Jul 12:00-15:00 UTC and at 19 Jul 09:00-12:00 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 expected to remain so.

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.
