Päikese aktiivsed piirkonnad ja pursked

The solar flaring activity was at low levels. The largest flare was an impulsive C6 flare, peaking at 17:38 UTC on June 13, associated with NOAA AR 3334. This flare was also associated with Type II radio emission. A new active region rotating over the south east limb also produced a number of C-class flares. NOAA AR 3327 has decayed into a plage region. NOAA AR 331 has also decayed. Newly numbered region NOAA AR 3333 has produced multiple low level C-class flared. The other regions on the disk are magnetically simple and did not produce any significant flaring activity. The solar flaring activity is expected to be at low levels over the next 24 hours with C-class flares likely and M-class flares possible.

In the last 24 hours there were no Earth-directed Coronal Mass Ejections (CMEs) detected in the available coronagraph observations.

Päikesetuul

The solar wind conditions reflected the waning influence of the high-speed stream (HSS). The solar wind speed decreased from 430 to 340 km/s. The total interplanetary magnetic field fluctuated around 6nT with a minimum Bz of -6 nT. The magnetic field orientation was predominantly in the positive sector (field directed away from the Sun). The solar wind speed is expected to continue to decrease over the next day, with a small chance of CME influence still on June 14. The high speed stream associated with the coronal hole which began to transit the central meridian on June 12 is expected to influence Earth from June 16.

Geomagnetism

During last 24 hours the geomagnetic conditions were at quiet to unsettled levels (NOAA KP 1-3 and K-Bel 1-3). Geomagnetic conditions are expected to be at quiet to unsettled levels on June 14. Active to minor storm conditions may also be possible from late on June 15 in response to the expected high speed stream.

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 gradually increase but remain below this threshold for the next day. The 24h electron fluence was at normal levels. The electron fluence is expected to be at normal levels in the next days.
