I was watching the sky from my living room window (faces west) with all the lights out looking for meteors maybe some aurora. the sun was below the horizon but there was still some twilight. i noticed a couple of stars and a plane or two from the airport at the northwest of the city when from the wsw direction(from my position) at about 50% a light appeared like a light turning on. it looked like another star but was moving toward the east. i had my binoculars beside me and looked at the light. i could see what looked like a small triangle with three lights at the corners and a light in the middle.No flashing lights or regular plane lights. the object moved at a steady speed but seemed slower then a passenger plane (see then everyday i face the city airport). shortly after it passed over my building a helicopter left the airport and fly over my building towards the direction of the object i seen. couldn't take picture because my phone's camera is too crappy.
