Today is what is known as the equilux and it happens when day and night are equal and occurs a few days before the spring equinox, and a few days after the autumn equinox. What appears to be a floating leaf is actually a stray sticking to a wet car windshield in a park in Scaggsville, Maryland on September 25, 2024.
