STD update 21:15 UTC 26 October

Updated: 21:15 UTC 26 October (4:10 pm EDT, 26 October):

A mild interplanetary shock was detected by the ACE spacecraft at 18:33 UTC. The shock reached the Earth at 19:07 UTC (2:07 pm EDT). The solar wind interplanetary magnetic field (IMF) appears to be shifting toward a gradual southward orientation, as is evidenced by a declining Bz component. If this trend continues, geomagnetic and auroral activity should begin intensifying within the next several hours, primarily over the higher latitude regions but probably with some activity visible from the middle latitudes as well. European observers should watch conditions closely.
