Solar alert

Issued on 2022 Aug 29 0616 UTC

A weak shock was seen in the solar wind at 02:56 UT, the magnetic field intensity jumped from 5 to 10 nT and the solar wind speed from 440 to 480 km/s. The shock is most likely driven by an ICME, showing only a glancing blow at the Earth so far, probably from the (expected) 27 August CME, although the speed is more indicative of an earlier candidate. At present, only active geomagnetic conditions have been reported (Kp = 4).
