1994 PC1 is a small asteroid around 1.1 kilometers in diameter which had a close approach to Earth in January 2021 during which it passed Earth at a distance of around 2 million kilometers.
Capturing this asteroid pass was by no means planned, I only read about the event a couple of hours before it happened. Luckily there was a small break in the clouds around the hour of its closest approach which allowed me to unpack the scope real quick and capture this 20 minute timelapse.
