... Nevertheless, the stars looked crisp at the ultra low power used to monitor the asteroid occultation. I observed the asteroid 54 minutes after the event, when it had moved 18” away from the target star, and the asteroid was barely visible with direct vision at 366x. So the asteroid was as faint as i ...
