Aktywne obszary słoneczne i rozbłyski

Solar flaring activity over the past 24 hours was at low levels, with multiple C-class flares observed. The largest flares were two C9.0 flares, peaking at 08:09 UTC and 11:20 UTC on August 26, both associated with NOAA AR 3796 (beta-gamma class). Currently, there are 12 numbered active regions on the visible disk. NOAA AR 3794 (beta class) is rotating over the west limb, while NOAA AR 3796 has been the primary driver of recent flaring activity, alongside NOAA AR 3794 and NOAA AR 3800 (beta-gamma class).Two new active regions (NOAA ARs 3803 and 3804) are rotating into the visible side of the Sun are expected to be the additional sources of the flaring activity in the next days. Solar flaring activity is expected to reach moderate levels over the next 24 hours, with M-class flares probable, and a small chance of X-class flares.

Koronalny wyrzut masy

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

Dziury koronalne

A small positive polarity low-latitude coronal hole has crossed the central meridian today, on August 26.

Wiatr słoneczny

Slow solar wind conditions were observed over the past 24 hours.The solar wind speed gradually decreased from the values about 340 km/s to the values around 295 km/s. The interplanetary magnetic field magnitude remained below 5 nT, with the Bz component fluctuating between -4 and 4 nT. The phi-angle was mainly in the positive sector (directed away from the Sun). Slow solar wind conditions are expected to prevail over the next few days, with a chance of a weak enhancement starting late on August 26, due to a possible glancing blow from the August 23 CME.

Geomagnetyzm

The geomagnetic conditions over the past 24 hours were quiet (NOAA Kp = 1-2). Quiet to unsettled geomagnetic conditions are expected over the next 24 hours with chances for isolated active conditions due to the possible glancing blow of the August 23 CME.

Poziomy przepływu protonów

Over the past 24 hours, the greater than 10 MeV GOES proton flux was at background levels and is expected to remain so in the next 24 hours, with possible enhancements in case of increased solar activity.

Strumienie elektronów na orbicie geostacjonarnej

The greater than 2 MeV electron flux, as measured by the GOES-16 satellite, remained below the 1000 pfu threshold. It is expected to remain below the threshold during the next 24 hours. The 24 hour electron fluence was at normal levels and is expected to remain at these levels for the following 24 hours.
