G1 (Minor) Geomagnetic Storms Expected on 06 November 2015
published: Saturday, November 07, 2015 22:57 UTC

An interplanetary shock hit the ACE spacecraft at 06/1735 UTC (1235 EST) and arrived at Earth at 06/1825 UTC (1325 EST).  This shock is believed to be the early arrival of the CME from 04 Nov and G1 (Minor) geomagnetic storms are expected in the next few hours.
