Frankenstorm: What the...

So, we're a tad freaked right now...

Cadence opted to sleep in the "playhouse" (a giant walk-in closet in the interior of the apt...really probably the safest place to be right now) so James kept her company in there while I cuddled with Hazel on the couch.  (Hazel was going to sleep in the playhouse but got very angry when bedtime came and ended up wanting to be with me wherever I was, so we settled in on the couch while mom sat next to us...

So, laying there in the semi-dark I start to see lightening...but it's odd, it's remarkably blue.  After several flashes I remarked to mom that it was quite the lightening, and she agreed, but it wasn't until a few minutes later, after James and I decided (based on how much the balcony door -which is pretty well protected by the terrace walls and not even on the side of the building that's taking the brunt of the storm - was shaking and straining) to close off the room with the leaky window (wind and rain coming through the glass...not terrible, but that is the window that's facing the hardest hit side of the house, and if the winds are going to continue to increase as they say, it's not one I want to rely on... ) and had herded the cats out of there and shut the door (SACRILEGE!) and James, mom and I were all back in the living room when we saw it for what it actually was...

"What the hell was that?"

So, I don't *think* it's lightening...it was a giant, bright blue sphere that appeared (as if blooming) on the horizon (at ground level) and flashed so bright it lit up the entire sky just as lightening does, and then retreated into itself and disappeared, as if closing up.  What. The. Crap.

I saw it first, and had just enough time to explain what it was before James was on his feet, seeing it for himself as it happened again behind my back, and then Mom was up too, and we all watched a third burst...it didn't happen again in a brief time and I realized that when I had been laying on the couch and noticed the blue quality of the "lightening" I was seeing, I had noted that it seemed like it was coming in waves...several (maybe three?  I wasn't really paying attention!) 'bolts' in a row, then nothing...

I have my camera at the ready now, so if I see it again I'm gonna grab it and try to record it...but that's probably a guarantee that it won't come back.  Does anyone have any clue as to what that could have been?  It was unlike any lightening I've ever seen (and I have seen ball lightening before), and it was originating from the exact same spot every time...I wouldn't call it a UFO 'cause, as I said, it seemed to be originating from the ground (or at least only slightly above it)...google did me no good, my searches only turned up UFO reports that didn't seem anything like what we saw...anyone else in the DC metro/MD area see this thing?  Anyone know what it is??

WEIRD.
