Aktywne obszary słoneczne i rozbłyski

The solar flaring activity was at low levels, with several C-class flares recorded in the past 24 hours. The largest flare was an C4.2 flare, peaking at 00:01 on Oct 25, associated with the region near N16E58. Other regions on the disc have simple configuration of their photospheric magnetic field (alpha and beta) and did not show any significant flaring activity. The solar flaring activity is expected to be at low level over the next 24 hours with a chance for C-class flares.

Koronalny wyrzut masy

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

Wiatr słoneczny

Over the past 24 hours the solar wind parameters were reflecting slow solar wind conditions. The solar wind speed decreased from values around 380 km/s to 300 km/s. The interplanetary magnetic field magnitude was below 6 nT. The southward component of the interplanetary magnetic field fluctuated between -3 nT and 6 nT. Slow solar wind conditions are expected to prevail during the next days, with a chance of a weak enhancement on Oct 26-27 due to arrival of a high-speed stream from a positive polarity coronal hole, that transited the central meridian on Oct 23.

Geomagnetyzm

Geomagnetic conditions over the past 24 hours were quiet (NOAA Kp: 0 to 1 and K-BEL: 1 to 2). Geomagnetic conditions are expected to be at quiet levels with a chance of increasing to unsettled and active conditions on Oct 26 - 27 in response to the high-speed stream arrival associated with the small equatorial coronal hole (positive polarity) that transited the central meridian on Oct 23.

Poziomy przepływu protonów

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

Strumienie elektronów na orbicie geostacjonarnej

The greater than 2 MeV electron flux remained below the 1000 pfu threshold as measured by GOES 16. It is expected to remain below this threshold over the next days. The 24 hour electron fluence was at normal levels and is expected to remain so.
