Päikese aktiivsed piirkonnad ja pursked

Solar flaring activity was low over the past 24 hours, with only C-class flares identified. The largest flare was a C2.0 flare (SIDC Flare 7143) peaking on March 08 at 15:07 UTC, which was produced by SIDC Sunspot Group 762 (NOAA Active Region 4387). A total of 5 numbered sunspot groups were identified on the disk over the past 24 hours, all having alpha or beta magnetic configuration. Solar flaring activity is expected to be low over the next 24 hours, with C-class flares very likely and a chance for M-class flares.

Krooniaine massiline väljavool

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

Krooniauk

The northern, mid-latitude, negative polarity coronal hole (returning SIDC Coronal Hole 142) has finished crossing the central meridian.

Päikesetuul

Over the last 24 hours, the solar wind parameters were enhanced, due to high-speed stream from SIDC Coronal Hole 142, which crossed the central meridian on March 05. The solar wind speed was around 550 km/s. The interplanetary magnetic field decreased from 10 nT to 5 nT with the Bz reaching a minimum value -7 nT. Enhanced solar wind conditions are expected to continue over the next 24 hours.

Geomagnetism

Geomagnetic conditions globally and locally were mostly quiet to unsettled (NOAA Kp 3) during the last 24 hours, with an active (NOAA Kp 4) interval between 00:00 UTC and 06:00 UTC on March 08. Unsettled to active conditions are expected over the next 24 hours, due to the ongoing influence of the high-speed stream from SIDC Coronal Hole 142.

Prootoni voo tasemed

The greater than 10 MeV proton flux remained below the 10 pfu threshold and is expected to remain so over the next days.

Elektronivoog geostatsionaarsel orbiidil

The greater than 2 MeV electron flux crossed shortly the 1000 pfu alert threshold, and is expected to cross again the threshold during the next 24 hours. The 24h electron fluence was at normal levels and is expected to remain so.
