Viewing Titan’s shadow on Saturn is only possible every 15-years consigning with Saturn’s tilt when the rings are lined up edge on. Now that Saturn is becoming an evening planet (rising around midnight 7/15), it is time to catch Titan’s shadow. Titan orbits Saturn once every 16 days. Here is a table of crossing events.

|---|---|---|---|
| 7/18 | 12:00 am | 2:44 am | 5:05 am |

Start looking for comet C/2023 A3 (Tsuchinshan-ALTAS) in the morning sky right before sunrise beginning Sept. 27 through to Oct. 1. This is the best chance for the comet to be seen at its brightest. Beginning after Oct. 9, the comet transitions into the evening sky, right after sunset. Easier time to view but the comet will begin to dim making it less prominent.
