In Autumn Awaiting Nova

No, it hasn't exploded yet, but the recurring nova T Coronae Borealis will eventually erupt and a seemingly "new" star will appear in the night sky. In October and through November the constellation Northern Crown sinks lower toward the western horizon in the evening twilight. If the nova blows up in 2025, you've got a chance of seeing it.


Looking over the Covington island, the U-shaped constellation Corona Borealis was visible at October 7 at 8:37 pm (sunset was 7:16 pm).

If it doesn't erupt soon, you'll have to shift your observing campaign to the morning hours and catch CrB before sunrise. It's a long winter of waking early. In March the constellation segues to a late night target, and by summer the observing hours become downright civil after twilight.


December opens with CrB low and setting to the northwest (NW) after sunset.
