Bülletään

There are currently five active regions visible on the solar disk. NOAA active region 2490 (Catania 16) has grown in size and number of sunspots, while NOAA 2489 has shrunk. NOAA 2492 turned into view, while another new (yet unnumbered) region has developed near S05W20 over the past period. All regions have a fairly simple configuration. The strongest flare was a C1.2 flare, originating from a region that is currently rounding the East limb. More flaring activity at the C-level is expected. No Earth directed CMEs were observed.

The solar wind was slightly disturbed from 14h UT on, when the solar wind speed started to rise from 280 km/s to maximum values near 400 km/s. This rise is believed to be associated to a stream emanating from the equatorial extension of the northern coronal hole. The magnitude of the magnetic field reach a maximum of 11 nT, with a fluctuating north-south Bz component between -8 and +8 nT. Geomagnetic conditions were disturbed during a few time slots, with local K (Dourbes) reaching K=2-3 and global estimated Kp (NOAA) reaching values up to K=4 and 5 early this UT morning due a period of negative Bz. Mainly quiet to unsettled geomagnetic conditions are expected, with a chance for a few slots of active conditions.
