Professor James McCanney said that when Comet ISON approaches Mercury on November 13-14 that Comet ISON will make Mercury form a halo effect due to electronically activity as the planet responses to the comet, and that this event may not be watched by North Americans because there could be a potential power grid or blackout.
In a New York times article dated August 16, 2013 The North American Utility Reliability Corporation is planning a power drill outage on November 13-14 called Grid Ex-II. This drill involves thousands of thousands of utility workers, business executives, National Guard officers, F.B.I. antiterrorism experts and officials from government agencies in the United States, Canada and Mexico are preparing for an emergency drill in November that will simulate physical attacks and cyberattacks that could take down large sections of the power grid. They will practice for a crisis unlike anything the real grid has ever seen, and more than 150 companies and organizations have signed up to participate.
The first drill by The North American Utility Reliability Corporation was in November 2011 (Grid Ex-I) and Comet Lovejoy was approaching the Sun but this time Comet ISON will be closer and effect planets in our solar system. McCanney said that the powers that may use the power grid shut as a false-flag and create fear and prevent North Americans from experiencing Comet ISON. What’s very interesting is that McCanney predictions does coincidence with a planned power grid shut down.
