Grazing occultation of Ganymede
Monday, September 25, 2023, 4:00 AM until 5:00 AM
Registration is not Required
On the morning of Sep 25th a very rare grazing occultation of Ganymede by Jupiter occurs between 4 and 5 a.m. EDT. Ganymede is only about 1.8 arc-seconds across so this event could be challenging to image or observe visually, but so cool if you’re lucky enough you see it. Well worth losing a couple of hours of sleep to give it a try.
