Bulletin

Two C-class flares were observed during the last 24 hours, with a C2.2 flare as the strongest one. The C2.2 flare peaked at 6:46 UT this morning and originated from NOAA active region 2522, which is located at the West limb. The flare was associated with a CME with first measurement at 7:00 UT in LASCO/C2. A first analysis indicates there is no Earth directed component, but further analysis will be needed to confirm this. There was also a radio type II burst observed (at Humain) and an enhancement in the proton flux at >10MeV was noted. The threshold for a proton event has not been exceeded at this moment, but further increases of the proton flux are possible. Flaring at the C-level is expected to continue.

The solar wind is still under influence of the coronal hole high speed stream, with solar wind speeds between 450 and 600 km/s. The magnetic field magnitude is nearly 10 nT with a fluctuating north-south component. Geomagnetic conditions reached minor storm levels (K=5) for several time slots before and after UT midnight, both at the local (Dourbes) and global (estimated NOAA Kp) level. Quiet to unsettled conditions, with a few isolated slots of active levels are expected.

Today's estimated international sunspot number (ISN): 063, based on 14 stations.
