Päikese aktiivsed piirkonnad ja pursked

The solar flaring activity was at low levels with several C-class flares being detected in the last 24 hours. The largest flare was a C6.3 flare, peaking at 09:14 UTC on June 06, associated with NOAA AR 3327 (beta class). This region was the main driver of the flaring activity over the past 24 hours. Isolated C-class flaring was produced by NOAA AR 3315 and NOAA AR 3317 from behind the west limb. NOAA AR 3323 (beta-gamma class) remains the largest and most complex active region on the visible solar disc but remained quiet. NOAA AR 3327 (beta class) is the second largest region on the visible disc. It has developed more trailing spots and enlarged its area, but has been silent. Other regions on the disc have simple configuration of their photospheric magnetic field (alpha and beta) and did not show any significant flaring activity. The solar flaring activity is expected to remain at low levels, with C-class flares likely and a chance for M-class flares.

No Earth-directed coronal mass ejections (CMEs) were detected in the available coronagraph imagery.

Päikesetuul

Over the past 24 hours the solar wind parameters (ACE and DSCOVR) were slightly elevated. The solar wind speed values ranged between 350 km/s and 420 km/s. The total interplanetary magnetic decreased from 10 nT to the values around 4 nT. The southward component of the interplanetary magnetic field fluctuated between -8 nT and 8 nT. The magnetic field orientation was predominantly in the positive sector (field directed away from the Sun). Similar conditions can be expected for the next days with a probability for further enhancements from late on June 7th, due to the CME associated with a filament eruption in the southwest sector on June 4th, which may have a glancing blow at Earth.

Geomagnetism

The geomagnetic conditions over the past 24 hours were quiet to unsettled. Similar quiet to unsettled conditions are expected for the next days. Active conditions may be possible from late on June 7th - early on June 8th due to a possible glancing blow ICME passage.

Prootoni voo tasemed

Over the past 24 hours the greater than 10 MeV GOES proton flux was at nominal levels and is expected to remain so over the next days.

Elektronivoog geostatsionaarsel orbiidil

The greater than 2 MeV electron flux was below the 1000 pfu threshold and is expected to remain below this threshold for the next days.The 24h electron fluence was at normal level. The electron fluence is expected to be at normal levels in the next days.
