There is now about an hour and a half of darkness between the end of Astronomical Twilight (10:25 pm) and moonrise, which last night occurred just after midnight. That interval will keep increasing as the moon wanes.

I was hoping to see some auroral activity, but those green and purple bands are just normal airglow, which the camera is good at detecting. Such colors are invisible to the unaided eye. In spite of the airglow, the sky was nicely dark with a reading of sqml=21.61 mpsas. Transparency was also good, with seven or more stars easily visible in the Little Dipper, which is in the upper right quadrant of the above photo.

| Regulus (blue) and Mars (Red-ish) setting over Bristol Head. |
As of last night Mars and Regulus (Alpha Leonis) are both of equal brightness at magnitude 1.4. Mars is separated from Regulus by slightly more than 1°. The above photo and the next one below were obtained with an Olympus E-M1iii camera, manual-focus Rokinon 85mm f/1.4 lens, and Hoya Softon-A filter.
