Aprox. 7:00 P.M. standing on balcony of Apt. witnessed bright starlike object moving NW to SW. Magnitude was brighter of surrounding stars which were just beginning to show. Luminosity was constant. Aprox. 1min of visual. Brighter than most satellites Ive seen. Could be ISS. Aprox. 10 to 15 min after, mutltiple sightings of likely satellites of various brightness and speed in multiple directions S to E, NW to SE, W to E. Occured between 7:10 to 7:30 P.M. While tracking one I then witnessed in the SW 3 to 4 extremely white bright flashes in one location. I was excited to see this amount of activity in short time period. Aprox. 8 to 10 planes in view before, during and after. Most headed W to E. 1 plane sighted 2 min after first account was very high from S to N as beacon lights very small. Also one the objects after first account appeared to wobble side to side then quickly faded way before reaching horizon.
