Three M-class flares were detected in the past 24 hours, all of them

produced by the Catania sunspot group 88 (NOAA AR 2192). The strongest

flare was the M8.7 flare peaking at 01:59 UT. Based on the still incomplete

SOHO/LASCO data and the absence of conspicuous eruptive signatures in the

SDO/AIA data, we conclude that there was no CME associated with this flare.

We expect flaring activity mostly on the M-level in this group, with a good

chance for an X-class flare. As the Catania sunspot group 88 approaches the

solar central meridian, a major eruption in this active region may lead to

a geoeffective CME and a proton event.The Earth is currently inside a slow

(around 460 km/s) solar wind flow with average (around 5 nT) interplanetary

magnetic field magnitude. The geomagnetic conditions are quiet and are

expected to remain so.
