night, Fri. 5/22/09, 11:33 EST, same exact time as prior night's event, same exact location in sky, but this night there was only one light/object in the near horizon night sky focal location, unlike the night before when there were a total of 3 lights/objects I observed. This night, had made sure my bi-noculars were out and ready for just this reason. Caught the light/object in my noculars, focused as best poss., observed same exact strobing lights, same exact colors (blue/white/green/no red), same exact lack of flash pattern to them, totally unlike any commercial, or even non-commercial aircraft FAA requirements/regulations I can think of. light would bop up/down, left/right, above/below treeline (treetops) directly across street neaighbors yard, same reference points I used night before. I have to be honest, I got kind of frustrated with it, it seemed to be playing games with, I think who/whomever may have been observing it. this is going to sound crazy, but I got so frustrated with it's "games", I kind of spoke out loud, as if maybe it had some wild intensive listening technology, hoping it might hear me, and I reprimanded it numerous times for being silly, and low and behold it disapeared. I'm not naive enough to think it actually responded to my criticism, but it did give me a chuckle. anyhow, event duration approx. 10 min. pretty much same exact event this time except this time only one light/object involved. sincerely, matt savadel, newark, de. P.S., PLEASE foreward to Butch Witkowski, or whoever is in his place at the time of your getting this report. Will be on look out for it tonight! thanks.
