Subject: First Day of Spring

According to the calendar it's March 20th and according to most of us it's the "first day of spring"

Well, when I looked out my window this AM it did not look like spring. There it was the white stuff that we've been looking at it seems every week. Just as some green started to show, the white stuff came and spoiled things.

So.... is it the first day of spring? "SPACE.COM" says

" The vernal equinox, which occurs at 7:02 a.m. EDT today (March 20), is probably the most important astronomical event of the year.

Although popularly described as "the first day of spring" in the Northern Hemisphere, the annual event is actually much more important than that. More than any other event, it marks the beginning of the astronomical year.

For something so important in astronomy, itís surprising that it is something that you cannot observe in any way in the night sky. Thatís because it involves the sun, which floods the sky with light and makes it impossible to see what is actually happening.

What happens on March 20 is that the sun moves from south of the celestial equator to north of the equator. The days, which have been getting longer since winter solstice on Dec. 21, now equal the nights in length, which is why this is called the "equinox" ó Latin for "equal nights."

So now you know.....the first day of spring is when you feel it.
