Bulletin
The solar activity was mostly quiet over the past 24 hours. Tow regions have turned over the East limb (NOAA-AR 2780, and NOAA-AR 27XX, which is not numbered yet). The second region has produced a C1.1-class flare. The solar activity is expected to remain mostly at low levels with a probability of small C-class flare. No Earth directed Coronal Mass Ejections (CMEs) were observed in the available coronagraphic imagery in the last 24 hours.
The greater than 10 MeV proton flux was at background levels over the past 24 hours. It is expected to stay at background levels for the next 24 hours. The greater than 2 MeV electrons flux was below the 10^3 pfu threshold over the past 24 hours. It is expected to remain at low level or the next 24 hours as the solar wind parameters are close to nominal levels.
The Earth is currently under the influence of the slow solar wind streams. The solar wind parameters (DSCOVR) showed nominal values with the solar wind speed varying between 350 km/s and 400 km/s, the total interplanetary magnetic field below 6.5 nT, and the Bz magnetic field components fluctuating between -3.3 nT and 6.4 nT. The solar wind conditions are expected to remain mostly nominal for the next days.
Geomagnetic conditions were quiet, and quiet conditions are expected for the next following days.
