Güneş Aktif Bölgeleri ve parlama

Solar flaring activity was moderate with one M-class flare and several C-class flares recorded over the past 24 hours. The largest flare was an M3.3 flare (SIDC 4531) peaking on June 02 at 11:18 UTC, associated with SIDC Sunspot Group 469 (NOAA Active Regions 4100; magnetic type beta-gamma). There are currently 5 numbered sunspot groups on the solar disk. SIDC Sunspot Group 469 was responsible for most of the flaring activity observed over the past 24 hours. The rest of these regions were mostly quiet. The solar flaring activity is expected to be moderate over the next 24 hours, with M-class flares expected and a chance for X-class flares.

Koronal Kütle Atılımı

No Earth-directed Coronal Mass Ejections (CMEs) were observed in the available coronagraph imagery.

Koronal delikler

A mid-latitude, negative-polarity coronal hole (SIDC Coronal Hole 111) began crossing the central meridian today, June 2. An associated high-speed stream may reach Earth starting late on June 5.

Güneş rüzgarı

Over the past 24 hours, the solar wind parameters were slightly disturbed under the ICME influence. The magnetic field reached values up to 25 nT, later decreasing to the values around 11 nT. The solar wind speed dropped from 1050 km/s to 700 km/s. The southward component of the interplanetary magnetic field fluctuated between -13 nT and 12 nT. Solar wind conditions are expected to remain slightly elevated due to the ICME passage.

Jeomanyetizma

Geomagnetic conditions reached severe storm levels globally (Kp 8-) between 12:00 and 15:00 UTC on June 1, due to the ICME arrival associated with the CME from early May 31. Locally, moderate storm conditions were observed (K_Bel 6). Further periods of minor to moderate storm conditions may be possible over the next 24 hours, with the ongoing ICME passage.

Proton akı seviyeleri

The greater than 10 MeV proton flux decreased below the 10 pfu mark at 22:30 UTC on June 01. The proton flux is expected to continue decreasing over the next 24 hours.

Jeostatik yörüngedeki elektron akıları

The greater than 2 MeV electron flux measured by GOES 19 was below the 1000 pfu threshold over the past 24 hours. The greater than 2 MeV electron flux is expected to remain below the threshold over the next 24 hours. The 24-hour electron fluence was at low to moderate levels and is expected to be at normal levels over the next 24 hours.
