At 8:39 pm on october 9/2019 i noticed a bright white light coming from the nw going across the sky. was so amazed that i got out my binoculars and watched as this round bright light silently went across the sky on a clear night. this round right light heading towards the se, got about 3/4 across the sky when suddenly in front of object it looked to me like a vortex or void even blacker than the sky opened up. then it seemed this light went into that vortex. to my surprise while still watching the void/vortex with my binoculars it started closing but not before i noticed a faint trail of light inside that void/vortex before it collapsed. it look as though whatever it was left a small trail of light inside that void/vortex before the void/vortex closed. i have seen many planes up here but this was definitely not a plane, it made no sound and was definitely a bright white light. there was no other objects beside the stars that i noticed in the sky during this event. what was so interesting was the void or vortex that opened that this object seemed to go into!
