This was the night of the COMET ISON perihelion and sublimation event November 27th. The cosmic wind would carry particles in a cone shape away from far side of the sun. So it is just a coincidence? But then maybe the sublimation happened over many days even a couple of weeks (not a single explosion) and perhaps particles were projected earthwards.
