On 11/13/20 (night before new moon)i went to alabama hills ca to do some astrophotography and time laspe of the milky way. i pointed my camera west north point above mt. whitney hoping to capture the milky way move across my viewfinder from left to right. exposure was set to 20 seconds with 10 seconds intervals. i began the time laspe around 640pm and finished 2 hours and 30 minutes after. the next day when i put the time laspe pictures together, there were the usually planes, satellites and numerous meteors in the imagines however, i noticed a object flying across up from bottom left corner following the left side of the milky way as it drifted across the sky. at first i thought it was a comet but it hit me that this object is moving extremely slow. planes, satellites and meteors move extremely fast in a time laspe. almost like a flash of laser. planes and satellites giving off dots of light with a line of light over it. meteors look like laser flashes. but this object moved so slowly, it wasnt blurry at all and looks like it was matching the movement of the stars and milky way as it moves across the sky. the strange part of the this object is, little pass halfway of the milky way, the object instantaneous vanishes and blink of a second later what looks like a blast of light and speeds away extremely fast! i check with nasa and jpl if any launches were scheduled on the day and evening and there was none. the only possibility i can seeing could have been is asteroid 2020vt4 that flew extremely close to earth that day. however the time and the location it flew by doesn't match to the time and location where i took my pictures.
