04/06/2021 – Ephemeris – The spring constellation of Leo

April 6, 2021 Comments off

This is Bob Moler with Ephemeris for Tuesday, April 6th. Today the Sun will be up for 13 hours and 3 minutes, setting at 8:17, and it will rise tomorrow at 7:12. The Moon, 2 days past last quarter, will rise at 5:48 tomorrow morning.

Tomorrow morning early risers will see the Moon near the planets Saturn and Jupiter. Specifically Jupiter, left of Saturn will be right above the waning crescent Moon.

Tonight however, will be a good time to check out Leo the celestial lion high in the southeast. His distinctive pattern of stars is a backward question mark, with the bright star Regulus as the dot on the bottom of it. It delineates the male lion’s head and mane. That pattern is also called the Sickle. While Leo is one of the official 88 constellations, the Sickle is an asterism, or informal constellation. Completing Leo is a triangle of stars below left of Regulus, his rump ending with the star Denebola, at the root of Leo’s tail. Leo is rich in mythology.

The astronomical event times given are for the Traverse City/Interlochen area of Michigan. They may be different for your location.


Jupiter and the Moon tomorrow morning

Leo tonight

Find Leo the lion high in the southeast from the Big Dipper (in the upper left) at 10 pm by imagining a hole in the bottom of the dipper that lets the water drip out. It will fall on the back of Leo. Created using Stellarium and GIMP.
