Bulletin

A single C1-flare occurred this UT morning, originating from NOAA active region 2521 (Catania 43). All regions remained relatively simple. Flaring activity at the C-level is possible (50% chance), with NOAA 2521 and 2522 as main candidates. No Earth-directed CMEs were observed.

Solar wind observations indicate a co-rotating interaction region (CIR) followed by a coronal hole (CH) high-speed stream (HSS). Near 16 UT on March 14, the solar wind speed first increased to about 550 km/s to increase further at 22h UT reaching almost 650 km/s. The Interplanetary Magnetic Field magnitude increased from about 5 nT to a maximum of 26 nT at 18h55 UT. The Bz component was variable between -21 and +20 nT. Geomagnetic conditions were at active (K=4) to minor storm (K=5) levels for several time slots from 18h UT on, both at local (Dourbes) and global (NOAA Kp) level. Unsettled to active conditions are expected for the next 24 hours.

Today's estimated international sunspot number (ISN): 050, based on 13 stations.
