The sensor recording x-ray radiation from the Sun is located on the GOES-15 satellite and has been the main source of information about solar flares in recent years is now showing the instability in a low radiation flux. This conclusion can be drawn from the analysis of the radiation profiles coming from the device. For this reason, from March 26, the LPI space weather centre was temporarily transferred from the information source coming from the GOES-14. It will be transferred back after stabilization of the situation and the operational restoration of the sensor.

A sharp increase in solar activity in last twenty-four hours is observed on the space monitors those providing the information on x-ray solar radiation flux. Yesterday, 20 March and today, March 21, three of the C-class flares have been recorded. The index of the flare activity for the first time in several months has reached the yellow level (peak value of 3.5 on a 10-point scale). The index of the flare activity for the first time in several months has reached the yellow level (peak value of 3.5 on a 10-point scale).

The Sun has come all of one day away from breaking its record for the longest period of inactivity for the last decade – reaching a mid-summer low and falling into yet another state of “hibernation”. Yesterday, on the first day of autumn, new sunspots appeared on the surface of the Sun following an absence of almost 50 days. The small group of just two spots was registered by the NOAA as number 1025 when it formed yesterday in the Sun’s northern hemisphere close to its eastern limb. Astrophysicists had to wait almost two months for this event: the group of sunspots occupying the last line of the catalogue (number 1024), vanished from the solar disk on 11 July this year.
