Slunečně aktivní oblasti a vzplanutí

Solar flaring activity was low over the past 24 hours, with only C-class flares identified. The largest flare was a C8.9 flare (SIDC Flare 7187) peaking on March 13 at 20:23 UTC, which was produced by SIDC Sunspot Group 820 (NOAA Active Region 4392). Most of the rest of the flaring was coming from on the westlimb (SSG 805/NOAA Active Region 4384) or behind the west limb. A total of 7 numbered sunspot groups were identified on the disk over the past 24 hours, all relatively small and with simple magnetic configuration (alpha or beta). 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.

Vyhazování koronální hmoty

The Coronal Mass Ejection (CME) detected in SOHO/LASCO-C2 data from 00:48 UTC March 13, was mainly directed southwards, and is not expected to impact Earth. No new Earth-directed Coronal Mass Ejections (CMEs) have been detected in the available coronagraph images.

Koronální díra

The large positive polarity trans-equatorial coronal hole (SIDC Coronal Hole 154) is still crossing the central meridian, now with it's southern midlatitude extension. The associated high-speed stream is currently enhancing solar wind conditions at Earth.

Solární bouře

The solar wind conditions were enhanced over the past 24 hours, due to the influence of the high-speed streams associated with the SIDC coronal hole 154 (which first reached the central meridian in Mar 11). The interplanetary magnetic field reached 13 nT, with the Bz reaching a minimum value of -10 nT. The solar wind velocity reached 700 km/s. Enhanced solar wind conditions are expected in the next 24 hours.

Geomagnetismus

The geomagnetic conditions reached globally moderate storm (NOAA Kp 6) and locally minor storm conditions (K BEL 5) since 22:00 UTC Mar 13, due to the high speed stream arrival of the SIDC CH 154. Active to minor storm conditions are expected for 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 remained below the 1000 pfu alert threshold, and is expected to remain below the threshold during the next 24 hours. The 24h electron fluence was at normal levels and is expected to remain so.
