Päikese aktiivsed piirkonnad ja pursked

The solar flaring activity was moderate during the last 24 hours, with one M1 flare produced by NOAA Active Region (AR) 3390 (magnetic type Beta) which peaked at 08:42 UTC today. Several C-class flares ranging from C1 to C6 were also produced in the last 24 hours: the brightest C6 by NOAA AR 3390 (magnetic type Beta). For the next 24 hours we are expecting few C-class flares and M-class flare from NOAA AR 3390. There are very likely a small chance of an X-flare.

Krooniaine massiline väljavool

No Earth-directed Coronal Mass Ejections (CME) were observed in the last 24 hours.

Krooniauk

A small positive polarity coronal hole has crossed central meridian, and it is expected to have an impact on Earth environment on 3 Aug.

Päikesetuul

Earth is presently inside the slow solar wind with velocity ranging from about 400 to 500 km/s and the interplanetary magnetic field ranging from 2 nT to 6 nT. The North-South component (Bz) ranged between -5 and 4 nT. We expect to see increase in the solar wind velocity once the expected CMEs arrive at Earth.

Geomagnetism

During the last 24 hours, the geomagnetic conditions were quiet to unsettled (NOAA Kp and K BEL 1 to 3) and we expect to see active condition or minor storm conditions when the expected CMEs arrive at Earth.

Prootoni voo tasemed

The greater than 10 MeV proton flux dropped below the 10 pfu threshold level yesterday at 16:30 UTC. It is expected to stay below the threshold level for the next 24 hours.

Elektronivoog geostatsionaarsel orbiidil

The 2 MeV electron flux, as measured by the GOES-16 satellite, was below the threshold level in the last 24 hours, and it is expected to remain below the threshold level in the coming 24 hours.
