Bulletin

Solar activity was mostly at low levels over the last 24 hours. Several active regions are on the solar disc visible from Earth. NOAA-AR 2972 and 2973, have both a beta magnetic field configuration but no significant activity has been recorded ; New regions are visible close to the East limb and have produced several B-class and C-class flares. For the next 24 hours, C-class flares are possible.

No Earth directed Coronal Mass Ejection (CME) has been detected in the available coronagraph imagery over the last 24 hours.

The greater than 10 MeV proton flux was at nominal levels in the past 24 hours and is expected to remain at nominal levels in the next 24 hours. The greater than 2 MeV electron flux remained below the 1000 pfu alert threshold and is expected to be close to the threshold in the next 24 hours. The greater than 2 MeV electron fluence was moderate levels in the past 24 hours and is expected to be at between nominal and moderate levels in the next 24 hours.

The solar wind parameters in Earth environment (as recorded by DSCOVR) showed an ambient background and slow solar wind speed regime. The solar wind speed fluctuated around 300 km/s and 400 km/s, the interplanetary magnetic field was ranging from 5 nT to 8 nT, and its southward Bz- component was fluctuating between -6 nT and 4 nT. The solar wind parameters are expected to remain close to nominal values for the flowing day.

The geomagnetic conditions were quiet to unsettled levels (K-BEL and NOAA- Kp recorded values of 1-3). Geomagnetic conditions are also expected to remain mostly quiet.
