太陽活動區和耀斑

Solar flaring activity over the last 24 hours has been at moderate levels, with multiple C-class flares and two M-class flares. The two flares were M1.6 flare peaking at 08:04 UTC and at 10:46 UTC on June 17, associated with the most complex sunspot region NOAA- AR 3712 (beta-gamma-delta). There are currently several sunspot groups on the solar disk, with NOAA AR 3712 (beta-gamma-delta) being the largest and the most complex one. The solar flaring activity is expected to be at moderate levels over the next 24 hours, with C-class flares expected, M-class flares probable and a small chance of X-class flares.

日冕物質拋射

No Earth-directed CMEs was identified and observed in the available coronagraph imagery in the last 24 hours.

日冕洞

A large mid-latitude north coronal hole with negative polarity is reaching the central meridian.

太陽風

Solar wind conditions were slightly enhanced in the last 24 hours due to the expected arrival of the high-speed stream from the equatorial, positive polarity coronal hole. The solar wind speed showed a slide increase up to 500 km/s for several hours before returning to value around 400 km/s. The interplanetary magnetic field is around 10 nT and the Bz component varied between -3.3 nT and 7.4 nT. The solar wind conditions are expected to return to slow the solar wind regime.

地磁

Geomagnetic conditions were at active levels (NOAA Kp 4, K BEL 4) due to the expected arrival of the high-speed stream from the equatorial, positive polarity coronal hole. Mostly quiet conditions are expected over the next 24 hours.

質子通量水平

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

地球靜止軌道上的電子通量

The greater than 2 MeV electron flux was below the threshold level in the last 24 hours and is expected to remain so over the next 24 hours. The 24h electron fluence is presently at normal levels and is expected to remain so over the next 24 hours.
