Aktywne obszary słoneczne i rozbłyski

The solar flaring activity was at low levels, with one C-class flare being detected in the last 24 hours. The largest flare was an C1.0 flare, peaking at 04:02 on Aug 28, associated with AR behind the west limb. There are five active regions visible on the disk. NOAA AR 3413 (beta class) and NOAA AR 3415 (beta-delta class) are the most complex active regions on the disk but were quiet. Other regions on the disc have simple configuration of their photospheric magnetic field (alpha) and did not show any significant flaring activity. The solar flaring activity is expected to be at low levels over the next 24 hours with C-class flares likely and M-class flares possible.

Koronalny wyrzut masy

There were no Earth-directed Coronal Mass Ejections (CMEs) detected in the available coronagraph observations in the last 24 hours.

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 460 km/s to 325 km/s. The interplanetary magnetic field magnitude was below 6 nT. The southward component of the interplanetary magnetic field fluctuated between -5 nT and 4 nT. The magnetic field orientation was predominantly in the positive sector (field directed away from the Sun). Slow solar wind conditions are expected to prevail during the next days, with a low chance of a weak enhancement on Aug 30 due to a possible arrival of the CME from Aug 26.

Geomagnetyzm

Geomagnetic conditions were quiet to unsettled (NOAA Kp<4 and K_BEL<4). Mostly quiet to unsettled conditions can be expected for the next 24 hours.

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 24 hours.

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 so in the next 24 hours. The 24 hour electron fluence was at normal levels and is expected to remain so.
