Slunečně aktivní oblasti a vzplanutí

Solar flaring activity was low over the past 24 hours, with only two C-class flares identified. SIDC Sunspot Group (SG) 820 (NOAA Active Region [AR] 4392, Beta magnetic configuration) and SIDC SG 831 (NOAA AR 4402, Beta magnetic configuration) produced a single triple-peaked, C3, flare (SIDC flare 7241) that peaked on 23 Mar at 00:12 UTC. SIDC SG 830 (NOAA AR 4401, Beta magnetic configuration) produced the second flare of the past 24 hours, a C1 on 23 Mar at 09:50 UTC. C-class flaring activity is expected to continue in the next 24 hours.

Vyhazování koronální hmoty

A Coronal Mass Ejection (CME) seen in LASCO-C2 images as launched on 22 Mar at 16:00 UTC is associated with a complex filament eruption and has a northern component that can possibly become geo-effective. Either the CME itself, or a glancing blow from it, is estimated to arrive on Earth the first half of 25 Mar and have a relatively minor impact. A CME seen in LASCO-C2 images as launched on 23 Mar at 00:00 UTC is expected to deliver a glancing blow on the first half of 26 Mar.

Solární bouře

The Solar Wind (SW) conditions remain strongly affected by a High Speed Stream (HSS) during the past 24 hours. The SW speed ranged between 650 and 700 km/s, while the interplanetary magnetic field (B) dropped from 13 nT to 3 nT, and its North-South component (Bz) increased from -12 nT to close to zero nT. For the next 24 hours a similar pattern is expected for the SW speed, while the magnetic field is expected to vary at around 5 nT.

Geomagnetismus

During the past 24 hours the global geomagnetic conditions reached the major storm levels (NOAA Kp 7- at 15:00 - 18:00 UTC) and moderate storm levels (NOAA Kp 6+ at 18:00 - 24:00 UTC and NOAA Kp 6 at 12:00 - 15:00 UTC) on 22 Mar. The local conditions followed a similar pattern during the same period of time but were milder. K BEL reached moderate storm levels (6) at 18:00-21:00 UTC and minor storm levels (5) at 15:00-18:00 UTC and 21:00-24:00 UTC. As the interplanetary magnetic field strength has became much weaker, the geomagnetic conditions are expected to drop, both globally and locally, to active or unsettled levels in the next 24 hours.

Úrovně protonového toku

The greater than 10 MeV proton flux, as measured by the GOES-19 satellite, was at background levels over the past 24 hours and is likely to remain so in the next 24 hours.

Elektronové toky na geostacionární oběžné dráze

The greater than 2 MeV electron flux as measured by GOES 19 was around the 1000 pfu threshold level during the past 24 hours. It is expected to marginally increase in the next 24 hours and remain around the threshold alert level. The 24-hour electron fluence was at normal levels during the past 24 hours. It is expected to reach moderate levels at some point in the next 24 hours.
