Solar Active Regions and flaring: Solar flaring activity was high during
the last 24 hours with an X1.7 flare produced by NOAA Active Region (AR)
3664 (magnetic configuration Beta-Gamma-Delta, Catania sunspot group 86).
NOAA AR 3664 and NOAA AR 3674 (magnetic configuration Beta, Catania sunspot
group 3) produced all of the M-class flaring activity of the past 24 hours.
NOAA AR 3664 is expected to continue its flaring activity at an M-class
level with a chance of an isolated X-class flare. NOAA AR 3674 is expected
to reduce its activity to the C-class level.

Coronal mass ejections: A halo Coronal Mass Ejection (CME) can be seen in
STEREO-A/COR2 and SOHO/LASCO images starting from yesterday 09:44 UTC. It
is estimated to be Earth-directed and is expected to arrive at Earth later
today.

Solar wind: During the last 24 hours the Solar Wind (SW) speed continue its
drop and the magnetic conditions continue to be undisturbed. The SW speed
dropped from 760 to 500 km/s, while the total interplanetary magnetic field
(Bt) varied between 3 and 9 nT. The North-South magnetic component (Bz)
ranged between -3 and 7 nT, while the interplanetary magnetic field phi
angle varied between directed away and towards the Sun. A Coronal Mass
Ejection (CME) is expected to arrive at Earth late today and cause
significant disruption.

Geomagnetism: Geomagnetic conditions were both globally and locally
unsettled to quiet (NOAA Kp 3+ to 2- and K BEL 3 to 2) during the past 24
hours. In the next 24 hours they are expected to reach active or minor
storm levels as a result of the expected arrival of a Coronal Mass Ejection
(CME).

Proton flux levels: The greater than 10 MeV proton flux, as measured by the
GOES-18 satellite, increased above the 10 pfu threshold level since
yesterday 14:20 UTC. It is expected to stay above this alert level for the
next 24 hours.

Electron fluxes at GEO: The greater than 2 MeV electron flux, as measured
by the GOES-18 satellite, increased to levels around the 1000 pfu alert
threshold. It is expected to remain close to the alert level for the next
24 hours.
The 24h electron fluence increased during the past 24 hours but remain at
low levels. It is expected remain at the same level in the next 24 hours.
