Solar Active Regions and flaring: The solar flaring activity was at high
levels with several M-class flares and two X-class flares during the last
24 hours. The strongest reported flare was GOES X4.0 flare which peaked at
06:54 UTC on May 10, produced by NOAA Active Region (AR) 3664. During the
flare, source region (AR 3664) of the flare had beta-gamma-delta
configuration of its photospheric magnetic field. The solar flaring
activity is expected to be at high to very high levels over the next 24
hours possibly with M-class flares and chance for X-class flare.

Coronal mass ejections: A partial halo coronal mass ejection (CME) was
observed on SOHO/LASCO-C2 images around 07:12 UTC on May 10. This CME is
associated with a X4.0 flare, which peaked at 06:54 UTC, produced by NOAA
AR 3664. Associated type II and type IV radio emissions were detected at
06:46 UTC and 06:51 UTC, respectively. This CME has a projected speed of
about 694 km/s (as measured by the Cactus tool). The corresponding ICME is
expected to impact the Earth on May 12.

Solar wind: Over the past 24 hours, interplanetary magnetic field was
slightly disturbed. The North-South component (Bz) ranged between -6 and 4
nT. The interplanetary magnetic field ranged from 0 nT to 7 nT. The solar
wind speed ranged from 450 km/s to 370 km/s. Enhanced solar wind parameters
associated with interplanetary coronal mass ejections (ICME) arrival are
expected as multiple CMEs associated with flaring activity from NOAA AR
3664, observed on May 08-09, possibly impact Earth late on May 10 or May
11.

Geomagnetism: Geomagnetic conditions were globally and locally at quiet to
unsettled conditions (NOAA Kp and K BEL 1 to 3). In the next 24 hours,
moderate to severe storm conditions (K 6 to 8) are expected as multiple
coronal mass ejections (CMEs) associated with flaring activity from NOAA AR
3664, observed on May 08-09, possibly impact Earth late on May 10 or May
11.

Proton flux levels: The greater than 10 MeV GOES proton flux started to
increase around 11:00 UTC on May 09, associated with coronal mass ejections
and flaring activities from NOAA AR 3664. It is increasing but still
remains below the 10 pfu threshold level. In the next 24 hours, it may
possibly cross the threshold level.

Electron fluxes at GEO: The greater than 2 MeV electron flux, as measured
by the GOES-16 satellite, was below the threshold level over the past 24
hours and is expected to remain so in the coming 24 hours. The 24h electron
fluence is presently at normal level and is expected to remain so for the
next 24 hours.
