Solar activity remained at low levels with no C- or higher-class flares detected in the last 24 hours. The only visible active region on the solar disk is now numbered as Catania 86 (NOAA 2814) with a bi-polar Bxo Beta classification. The X-ray flare activity is expected to remain low for the next 24 hours with a slight chance for a C-class flare due to the unnumbered active region.

A sequence of two coronal mass ejections (CMEs) was observed in LASCO C2/C3 and STEREO A COR2 imagery related to prominence eruptions from the south- east limb during the UTC morning of April 12th. Currently these CMEs have no estimated Earth-directed component.

The greater than 10 MeV proton flux was at nominal levels in the past 24 hours and is expected to remain so in the next 24 hours. The greater than 2MeV electron flux remained under the 1000 pfu threshold and is expected to remain so. The 24h electron fluence was at nominal levels and is expected to remain in the next 24 hours.

Over the past 24 hours all solar wind parameters (ACE and DSCOVR) were at low levels. The solar wind speed slowly varied in the range of 341 to 387 km/s. The total magnetic field varied between 0.6 and 5 nT with a weakly varying Bz component in the range of -4 to +3 nT.

The geomagnetic conditions over the past 24 hours were globally quiet and mostly quiet locally with a single hour of unsettled geomagnetic conditions registered at Dourbes between 19:00 and 20:00 UTC on April 12th. Quiet to unsettled geomagnetic conditions are expected for the next 24 hours.
