Сонячно-активні області та спалахи

Solar flaring activity was moderate over the past 24 hours, with 1 M-class flare identified. The largest flare was a M1.2 flare (SIDC Flare 7174) peaking on March 13 at 09:55 UTC, which was produced by SIDC Sunspot Group 805 (NOAA Active Region 4384). Most of the rest of the flaring is coming from on (SSG 805) or behind the west limb. A total of 8 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.

Корональні викиди маси

A Coronal Mass Ejection (CME) is detected in SOHO/LASCO-C2 data from 00:48 UTC March 13, mainly directed southwards. This CME is associated with a filament eruption, and will be further analysed for earth directed component.

Корональні діри

The large positive polarity transequatorial coronal hole (SIDC Coronal Hole 154) is still crossing the central meridian, now with it's midlatitude extensions. The associated high-speed stream arrived earlier today at Earth.

Сонячний вітер

Solar wind conditions were slow at the beginning of the reporting period, but are enhanced since around 08:00 UTC on March 13th under the influence of the high speed stream arrival associated with the positive polarity SIDC Coronal Hole 154. The solar wind speed has increased to 470 km/s, the interplanetary magnetic field reached 13 nT, with the Bz reaching a minimum value of - 8nT. Enhanced solar wind conditions are expected to continue over the next 24 hours, due to the High speed stream.

Геомагнетизм

The geomagnetic conditions were globally and locally mainly quiet to unsettled, with one isolated active period (Kp 4) between 03:00 and 06:00 UTC on March 13. Active to minor storm conditions are expected for the next 24 hours, due to the high speed stream arrival.

Рівні потоку протонів

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.

Потоки електронів на геостаціонарній орбіті

The greater than 2 MeV electron flux measured by GOES-18 and GOES-19 was above the 1000 pfu threshold for the beginning of the reporting period, but has now dropped below the threshold and is expected to remain below the threshold for the next 24 hours. The greater than 2 MeV electron flux may exceed the 1000 pfu threshold over the next 24 hours. The electron fluence was at moderate levels over the past 24 hours, but is expected to be at normal levels over the next 24 hours.
