Bulletin

Solar activity is low, a small chance for C-class flaring can come from NOAA AR 1555/Cat 91 or from the newly emerging active regions on the East limb (Cat 93 and Cat 94). This morning from 01:00 UT onwards, the ACE spacecraft recorded a small jump in the solar wind speed, up to 600 km/s, and a gradual increase in the solar wind density. Together with Southward fluctuating IMF, this had generated a Kp=6 geomagnetic storm. The event is probably a consequence of the halo CME that left the Sun on midnight Sept 29/30, which arrived earlier than expected. By now, the IMF is back steadily Northward so we expect the worst of the storm has passed. Later today we expect a return to quiet geomagnetic conditions.
