Bulletin
Flaring activity is very low. The X-ray background radiation is situated at the B-level. Solar wind speed has decreased to around 400 km/s. The magnitude of the interplanetary magnetic field is at 10 nT, with a negative Bz component. Current geomagnetic conditions are unsettled, which are expected to continue or increase to active levels during the next few hours.
