So, no more than half hour ago this weird thing happened in NYC, where I live.

Strange lights in the sky somewhere either over Manhattan or over the East River persisted form over ten minutes.
Before I was made aware of the lights, I noticed some strange electrical phenomena in my room. Lights were dimming and brightening slowly.

My mother says she noticed the same thing with the lights in the kitchen. Already youtube is being flooded with new uploads on this "Event".

If anyone can help me figure out what exactly just happened that would be great.
