I have seen bizarre lights repeatedly over my house for weeks. i have watched as many as 10 of them move erratically, move slowly, hover, etc. i bought high power binoculars to see what it was. i observed at sunset on two occasions (yesterday and today) a black boomerang triangle with lights. i wouldn't have known what it was had it not been for the binoculars. it made no sound, no smoke, it glided from one end of the sky to above my house (again appears only as a pulsating light until i saw through the binoculars). the lights appear almost every night from sunset for several hours. i assume that those lights are the same as the black boomerang that appeared at sunset given they pulsate in the same way, but i have no way of knowing given its dark at night. initially i questioned if this was some sort of drone. seeing it through the binoculars confirmed this was neither a drone nor a plane. it was definitely engineered, it had lights on it that were pulsating. i want to emphasize that the sky was crystal clear and i was looking at this during the sunset (it was still light) and there was no smoke and no sound.
