Päikese aktiivsed piirkonnad ja pursked

Solar flaring activity over the past 24 hours was at moderate levels. The largest flare was a M1.65-flare, with peak time 10:30 UTC on August 17 and is associated with NOAA AR 3784 (beta- gamma-delta). The second largest flare was a M1.33-flare, with peak time 13:20 UTC on August 16 and is associated with an active region over the west limb. There are currently 10 numbered active regions on the visible disk. NOAA AR 3784 (beta-gamma-delta) is the largest and most magnetically complex regions on disk. NOAA AR 3790 (beta-gamma) has produces most of the flaring activity in the last 24 hours. NOAA AR 3786 (beta) has started to rotate over the west limb. NOAA AR 3782 has turned into a plage region. The solar flaring activity is likely to be at moderate levels over the coming days with C-class flares expected, M-class flares very likely and a small chance for an X-class flare.

Krooniaine massiline väljavool

No Earth-directed Coronal Mass Ejections (CMEs) have been detected in the available coronagraph images.

Päikesetuul

The solar wind conditions reflected a slow solar wind regime. The solar wind speed varied between 306 km/s to 363 km/s. The interplanetary magnetic field varied between 2 nT and 7 nT, with the Bz reaching a minimum value of -5 nT. The phi-angle was mainly in the positive sector (directed away from the Sun) with periods in the positive. The solar wind is expected to become perturbed to the expected arrival of an CME from August 14.

Geomagnetism

Geomagnetic conditions were globally and locally quiet to unsettled (NOAA Kp 1 - 3 and K BEL 1 - 3). Geomagnetic conditions are expected to reach active levels in the next 24 hours.

Prootoni voo tasemed

Over the past 24 hours the greater than 10 MeV GOES proton flux was at background levels and is expected to remain so over the next days.

Elektronivoog geostatsionaarsel orbiidil

The greater than 2 MeV electron flux measured by GOES 16 was below the 1000 pfu threshold and is expected to remain so in the upcoming days. The 24h electron fluence was at nominal level and is expected to remain so in the next days.
