Today is May Day, and is known in the Celtic tradition as Beltane, marking the traditional half-way point between the spring equinox and the summer solstice. These mid-points of the seasons are called “cross-quarter days”, as they are exactly between the “quarter days”, marking the beginning of each season.

Catching astronomy events before sunrise in May gets more challenging as the Sun rises earlier and earlier. If you can get your eyes open between 4:30 and 5:00 AM tomorrow, the waning Crescent Moon shines to the right of the planet Saturn, low in the east-southeast. The Moon returns to visit Saturn at the end of this month – even earlier!

Although the twilight starts early, and overwhelms most of the stars by quarter of 5 in the morning, early risers tomorrow morning will enjoy an engaging arrangement of the waning Crescent Moon, sitting between Saturn on the right, and Mars on its left. They are low in the east-southeast from 4:30 until twilight get too bright by 5:00 AM.
