Solar Active Regions and flaring: 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.

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

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

Solar wind: 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.

Geomagnetism: 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.

Proton flux levels: 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.

Electron fluxes at GEO: 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.
