Bülletään

The solar activity was quiet over the past 24 hours. The unipolar sunspot region (Catania 37, N0AA-AR 2767) remained stable and did not produce any flaring activity. X-ray flux is below B-class level and the solar activity is expected to remain at low levels.

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 electron flux fluctuated between nominal and moderate levels over the past 24 hours. It is expected to remain nominal to moderate levels over the next 24 hours.

The Earth is under the influence of the slow solar wind streams. The solar wind parameters (DSCOVR) was mostly at nominal values with the solar wind speed around 270-330 km/s. The total interplanetary magnetic field was slightly more enhanced and reached the values around 7.7 nT, probably due to some interaction with wind steams coming from polar coronal holes. The Bz magnetic field components fluctuated between -6.1 nT and +6.0 nT. The solar wind is expected to remain slow for the next days.

Geomagnetic conditions were quiet, and quiet to unsettled conditions are expected for the next following day.
