Space weather - Solar activity has been at a very low level. Although an oblast, numbered in the form of 2737 (N12E43, Bxo/beta) is formed on the solar disk, it is not active. The images obtained did not show any Coronal Mass Ejections (CME). During the reporting period, there was no ignition.

During the reporting period, the flood of more than 2 MeV energy loaded electrons were normal and low level. The flood of more than 10 MeV energy loaded protons remained stable at the background level throughout the entire reporting period.

During the reporting period, the solar wind parameters were normal. In the first half of the reporting period there was a slight increase in parameters due to the weak effect of CIR (Co-rotating Interaction Region) in front of CH HSS (Coronal Hole High Speed Streams) with negative polarity. The solar wind speed has fallen from 420 km/s to 390 km/s. The total magnetic field changed in the range of 4-5 nT and the Bz component was -2.07 nT. The Phi angle is mainly concentrated in the negative sector.

Although the geomagnetic field was generally quiet during the last 24 hours, a weak activity (Kp=1-2) was recorded in the time interval of 31 March/00.00 - 03.00 UTC.

Space weather forecast - Solar activity will remain at a very low level during forecast days (April 01-03).

It is expected that flood of more than 2 MeV energy loaded electrons will remain at low or medium levels during the prediction period (April 01-03). It is expected that flood of more than 10 MeV energy loaded protons will continue at the background levels during the forecast period (April 01-03).

During the forecast period (01 - 03 April), due to the effect of the CH HSS effect, there will be a slight increase in solar wind parameters.

During the forecast period (01 - 03 April), general calm in the geomagnetic field is predicted (mainly Kp=2). Magnetic hurricane is estimated to be less than 5%.
