Bulletin

Solar flaring activity was at very low levels. No significant flares have been recorded. Solar activity is expected to remain at very low levels.

No Earth directed Coronal Mass Ejections (CMEs) were observed in the available coronagraphic imagery.

The greater than 10 MeV proton flux was at background levels the past 24 hours. It is expected to remain so in the next 24 hours. The greater than 2 MeV electron flux was at nominal levels over the past 24 hours and is expected to stay at nominal levels for the next 24 hours.

The solar wind slowed down and its speed near Earth oscillated between the values of 310 to 355 km/s (DSCOVR). The Interplanetary Magnetic Field (IMF) did not have a dominant polarity, with the phi angle switching between the positive and negative sector. Bz varied between -5 and +3 nT. The magnitude of the magnetic field varied between 1 and 7 nT. For the next 24 hours the solar wind speed is expected to stay at those levels.

Quiet to unsettled geomagnetic conditions were registered for the past 24 hours (K Dourbes recorded values 1-3 and NOAA Kp 1-2). Quiet to unsettled (K Dourbes = 3) geomagnetic conditions are expected for the next 24 hours.

Dnešní odhadovaný mezinárodní počet slunečních skvrn (ISN): 000, na základě 14 stanic.
