Aktywne obszary słoneczne i rozbłyski

Solar flaring activity was moderate over the past 24 hours. The largest flare was a M2.7 flare (SIDC Flare 7220) peaking on March 16 at 12:15 UTC, which was produced by group 820 (NOAA Active Region 4392). This region is the largest on disk, with Beta-Gamma magnetic configuration. This region also produced an M1.3 flare (SIDC Flare 7222), peaking on March 17 at 09:04 UTC. There are currently 5 numbered regions on the disk. The other regions are simple and mostly quiet. Solar flaring activity is expected to be low over the next 24 hours, with C-class flares expected and further isolated M-class flares possible.

Koronalny wyrzut masy

An asymmetric halo Coronal Mass Ejection (CME) was first detected in LASCO-C2 data from 12:36 UTC on March 16. This was associated with the M2.7 flare (SIDC Flare 7220) from SIDC sunspot group 820 (NOAA Active Region 4392) located near the central meridian. There was a large on disk dimming and Type II and Type IV radio emission associated with this event. The CME was relatively slow around 550 km/s and initial analysis suggests an arrival at Earth from late on March 19. A filament around S05W10 also began to lift off around 03:00 UTC March 17 but no CME is yet visible in the coronagraph data.

Dziury koronalne

The southern midlatitude extension of the large positive polarity coronal hole (SIDC Coronal Hole 154) is still crossing the central meridian.

Wiatr słoneczny

Over the past 24 hours, the solar wind parameters reflected the waning influence of the high speed stream associated with SIDC Coronal Hole 154. The solar wind speed decreased from 550 kms to around 480 km/s. The total magnetic field was stable around 5 nT. Bz had a minimum of -4 nT. The interplanetary magnetic field phi angle was mostly in the positive sector (directed towards the Sun). The influence of the current high speed stream is expected to continue to decrease over the next 24 as the parameters gradually return to slow solar wind conditions.

Geomagnetyzm

Over the past 24 hours, the geomagnetic conditions reached unsettled levels globally and locally (NOAA KP 3 and K BEL 3). Quiet conditions are expected over the next 24 hours, with possible isolated unsettled to active conditions possible due to the ongoing high speed stream influence.

Poziomy przepływu protonów

The greater than 10 MeV proton flux was below the 10 pfu threshold over the past 24 hours. It is expected to remain below this threshold level over the next 24 hours.

Strumienie elektronów na orbicie geostacjonarnej

The greater than 2 MeV electron flux, as measured by GOES-18 and GOES-19 satellites, exceeded the 1000 pfu threshold. The greater than 2 MeV electron flux is expected to again exceed the 1000 pfu threshold over the next 24 hours. The electron fluence was at normal to moderate levels and is expected to be at moderate levels for the next 24 hours.
