Double Shot CME's Have Arrived - June 16, 2012

The CME that occurred on June 13th and the CME from June 14th have merged in space en route to Earth and we are now seeing the front of the CME's arrive at Earths magnetosphere.
The density is slowly rising over the recent hours. We believe the main mass of the CME's has not yet hit. We come to this conclusion because of the merging in space of the 2 CMEs, the 1st CME was only a glancing blow, thus the front of the impact would be to the side.
The 2nd CME was a direct shot, thus the middle part of the impact would be more of a direct hit. We should see the results of this in the coming hours. A high latitude aurora watch is in effect for the evening of June 16, 2012. Auroras possibly visible as low as Michigan,  New York, Wisconsin, Washington and Main.

Continue to check back often for further updates and alerts as the expected geomagnetic storm progresses. All updates will be added to the bottom of this report.
