No significant flaring activity was observed during the last 24 hours. NOAA active regions 2519, 2521 were stable, while NOAA 2522 rounded the West limb. NOAA 2523 and 2524 were newly numbered regions but currently have no flaring potential. A new region is emerging near N10E05. There is a probability of 30% for C-class flares. The CME mentioned in the previous bulletin (with first measurement at March 16, 7:00 UT in LASCO/C2) is travelling well of the Sun-Earth line and is expected to have no consequence for the Earth environment. The proton flux at >10MeV has nearly returned to the background level.
The solar wind is still disturbed due to high speed stream influences, with solar wind speed currently around 600 km/s. The magnetic field magnitude ranges between 5 and 10 nT. Due to a prolonged period of negative Bz, geomagnetic conditions were at minor storm levels (K=5) at global level (NOAA estimated Kp) and at active levels at Dourbes. A few time slots of active levels are well possible for the next 24 hours.
Today's estimated international sunspot number (ISN): 061, based on 19 stations.
