What big event is only 1 MONTH away?? Check the picture for a clue! On April 8th, there will be a Total Solar Eclipse & SE Wisconsin will experience approximately 88-92% coverage. (Not 100% totality, but still pretty darn good!)

Similar to Feb., Venus will be the brightest planet, Venus these March mornings. It will be very low in the E-SE sky shortly before sunrise. You’ll most likely need a clear sight-line to the horizon and probably something to block the glare of the rising Sun to see it.

Show Tonight
TOMORROW is Feb. 29 (Leap Day)! Why? Because it takes about 365.25 days for Earth to orbit the Sun but our calendars have only 365 days. To make up for the extra ¼ day, we add one day—February 29—to years that are divisible by 4 (2024, 2028, & so on), & call it Leap Day!

Calling all early birds! Have U been able to sneak a peek at Venus & Mars in the SE yet? These 2 planets are less than half-a-degree apart, but Mars will be dimmer. Keep in mind that the rising Sun’s glare and Mars’s proximity to the horizon might make them difficult to spot.

February Shows
It should be no surprise that Native Americans named February full moon- Snow Moon. Why? Because the heaviest shows usually fell during this time. Some tribes also refer to this Moon as the Full Hunger Moon, since harsh weather conditions in their areas made hunting difficult.
