The Ides of March meant the middle of March to the Romans, and specifically the Full Moon, because their calendar was a lunar calendar. Today’s standardized calendars are no longer lunar, which explains why the Moon is not Full, but a wide, waxing Crescent, well to the upper right of the reddish star Antares, the “red eye” of Taurus, the Bull.

Over the next 10 days, the planet Mercury puts on an excellent display in the western twilight, though our closest planet to the Sun never appears very high. Find a low, level view to the west, and starting near 7:30 PM, scan a little more than a hand-width above the spot that would be level. It will be bright, but low.

The Big Dipper looks like a question mark in the northeast. After months of asking “when is Spring?”, follow this question mark’s curve to find a star that announces Spring to our skies. Rising near 8:00 PM this evening, the bright star Arcturus comes up in the east-northeast, arriving each March in the evenings.
