Solar flaring activity over the past 24 hours was at moderate levels. The largest flare was a M2.5-flare, with peak time 01:32 UTC on October 01, associated with NOAA AR 3451 (beta-delta), this active region produced most of the flaring activity in the last 24 hours. There are currently 7 numbered active regions on the visible disk, NOAA AR 3445 has started to rotate off the west limb, NOAA AR 3449 (beta-gamma) and NOAA AR 3450 (beta-gamma) are both stable, all other regions have simple alpha or beta magnetic field configurations. The solar flaring activity is likely to be at moderate levels over the coming days with C-class flares expected, M-class flares possible and a low chance for isolated X-class flaring.
No Earth-directed CMEs have been detected in the last 24 hours. A CME was seen erupting towards the east in LASCO-C2 data from 16:10 UTC on October 01 and another was seen erupting towards the south-west in LASCO-C2 data from 18:44 UTC on October 01 both CMEs are determined to be back-sided and are not expected to impact the Earth.
A positive polarity coronal hole has crossed the central meridian at the equator.
The greater than 10 MeV proton flux was at background level over the last 24 hours and is expected to remain so in the next 24 hours.
The greater than 2 MeV electron flux measured by GOES-16 went above the 1000 pfu threshold value between 13:15 UTC and 18:30 UTC on October 01. The greater than 2 MeV electron flux is expected to increase above the threshold again in the next 24 hours. The 24h electron fluence was at moderate levels and is expected to remain at moderate levels in the next 24 hours.
