Bulletin

NOAA AR 2740 is the only visible active region on the solar disc. It produced a C2.1 flare peaking at 22:43 UT on May 4 and several narrow (not Earth directed) CMEs. More C-class flares can be expected

No Earth directed CMEs in past 24 h. Solar protons have remained at background levels over the past 24 hours.

The solar wind speed is at 440 km/s with interplanetary magnetic field magnitude of 4 nT. Geomagnetic conditions have been mostly unsettled with an active period detected at Dourbes (k = 4 between 15:00 UT and 17:00 UT on May 4), due to several hours of negative Bz. The solar wind from an equatorial negative polarity coronal hole will affect the Earth on May 6-7. Active conditions can be expected then.

Today's estimated international sunspot number (ISN): 013, based on 16 stations.
