The solar flaring activity was at low levels, with only low-level C-class flares recorded in the past 24 hours. The largest flare was an C2.3 flare, peaking at 23:59 on Aug 28, associated with the AR behind the east limb (N22E87). There are five active regions visible on the disk, a new region rotated over the east limb (NOAA AR 3417). NOAA AR 3415 (beta-delta class) is the most complex region on the disk but was quiet. NOAA AR 3413, that gained complexity from beta to beta- gamma class, produced only low C-class flares. 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.
There were no Earth-directed Coronal Mass Ejections (CMEs) detected in the available coronagraph observations in the last 24 hours.
A positive polarity coronal hole in the northern hemisphere transited the central meridian today.
Over the past 24 hours the solar wind parameters were reflecting near slow solar wind conditions. The solar wind speed ranged between 320 - 370 km/s. The interplanetary magnetic field magnitude was below 8 nT. The southward component of the interplanetary magnetic field fluctuated between -6 nT and 7 nT. Similar 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.
Geomagnetic conditions were quiet (NOAA Kp: 1 - 2 and K-BEL: 1 - 2). Geomagnetic conditions are expected to be at mostly quiet levels, with a small chance of increasing to unsettled and active conditions on Aug 30, due to a possible arrival of the CME from Aug 26.
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.
The greater than 2 MeV electron flux, as measured by the GOES-16 satellite, was below the 1000 pfu threshold and is expected to remain below this threshold for the next days.The 24h electron fluence was at normal level. The electron fluence is expected to be at normal levels in the next days.
