Сонячно-активні області та спалахи

Solar flaring activity was moderate over the past 24 hours. There were two low level M-class flares recorded. There are currently 11 numbered regions on the disk. SIDC Sunspot Group 860 (NOAA Active Region 4455) was the largest and most complex region on disk (magnetic type beta) and produced an M1.2 flare (SIDC Flare 7825) peaking on June 02 at 10:05 UTC. A new region rotated onto the disk in the south- east and was numbered SIDC Sunspot Group 889. This region produced an M1.2 flare (SIDC Flare 7824) peaking on June 02 at 04:45 UTC. The remaining regions are simple and mostly quiet. Solar flaring activity is expected to be low over the next 24 hours, with C-class flares probable and M-class flares possible.

An eruption was observed in SDO AIA 304 near SIDC Sunspot Group 860 (NOAA Active Region 4455) around 03:00 UT. An associated Coronal Mass Ejection (CME) was observed in SOHO/LASCO-C2 data from 03:12 UTC directed to the north (SIDC CME 664). The majority of this eruption appears to be directed north of the Sun-Earth line, but modelling is ongoing to determine if there may be an Earth directed component. An on disk dimming was observed near SIDC Sunspot Group 860 (NOAA Active Region 4455) associated with the M1.2 flare (SIDC Flare 7825). Any possible associated CME will be analysed when coronagraph data become available. No other Earth directed CMEs were detected in the available coronagraph imagery.

Сонячний вітер

Over the past 24 hours, the solar wind parameters reflected slow solar wind conditions. The solar wind speed was between 380 and 440 km/s. The total magnetic field ranged between 5 and 7 nT. Bz had a minimum of -6 nT. The interplanetary magnetic field phi angle was mostly in the negative sector (directed towards the Sun). Slow solar wind conditions are expected on June 02 with an enhancement possible from June 03, due to the influence of the high speed stream associated with the positive polarity coronal hole which began to cross the central meridian on May 31 (SIDC Coronal Hole 166).

Геомагнетизм

The geomagnetic conditions were at quiet to unsettled levels globally and locally (NOAA Kp and K Bel 1-3). Quiet conditions are expected on June 02. Active conditions with possible minor storm intervals are possible from June 03, due to the possible high speed stream influence.

Рівні потоку протонів

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.

Потоки електронів на геостаціонарній орбіті

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