About this image

The 43 km diameter asteroid (1421) Esperanto, mag 15.1, occulted a mag 14.1 star in Auriga for 2.56 s.

The 'scope was being buffeted by strong winds, which thankfully became almost calm for the brief occultation. As the target star was occulted a group of nearby faint stars became visible. My second positive occultation this year, equalling my tally from the whole of 2021.
