There are currently five sunspot groups visible, as identified by Catania. The most interesting group is Catania group 5 (NOAA 2473), which produced an M4.7 flare (peaking at 0:40 UT today) and two C-class flares during the past 24 hours. The M4.7 flare was associated with a dimming, a type II radio burst and an eastward CME. The CME had an apparent width of 70 degrees and an estimated projected speed of 530 km/s (as reported by CACTus). First analysis indicates that no influence on the Earth environment should be expected. Flaring at the M-level is expected to continue, in particular from the Catania group 5, with a slight chance for an X-class flare. The solar wind speed is varying between 400 and 500 km/s. The interplanetary magnetic field (IMF) magnitude is below 10 nT, with a fluctuating Bz component. Quiet to unsettled conditions (K < 4) were noted by Dourbes and NOAA. These geomagnetic conditions are expected to continue.
