Subsiding geomagnetic storm (May 04, 2012)
Earth is exiting a solar wind stream that has been stirring up geomagnetic storms around Earth’s poles since April 29th. Over the past few nights, observers have seen auroras over the South Pole, Germany, Wisconsin andMichigan. The chances for more auroras are subsiding as Earth exits the stream.
The geomagnetic field ranged from active to quiet as coronal hole (CH) high-speed stream (HSS) effects continued to decline. The greater than 2 MeV electron flux at geosynchronous orbit was at high levels throughout the period.
