Solar eclipse, Supermoon, Spring Equinox: Friday Will See Three Rare Celestial Events


From the article:

As the eclipse plunges the UK and other places into darkness this Friday, two other rare if less spectacular celestial events will be taking place, too: a Supermoon and the Spring equinox.

And:

The equinox will happen at the same time as a solar eclipse in 2053 and 2072, though it doesn’t always appear as close together as that.

The title isn’t exactly correct. The Spring equinox happens every year. Maybe the three coinciding is what’s rare, I’m assuming.

To the author, Mr. Andrew Griffin, who wrote:

“On March 20, the Earth’s axis will be perpindecular to the sun’s rays — which only happens twice a year, at the two equinoxes. After that, it will start tipping over…”

Nope. The Earth’s axis will not start tipping over.
It never does.
Try again to explain correctly what happens.

“The Earth’s axis will not start tipping over.
It never does.”

No. There will be some tipping over, such that the plane of the earth’s equator will cut through that of the ecliptic some 11.5 mins earlier than this year…..but I suspect that will come as a surprise to the writer of this article.

Hence the need to change from the primitive Julian calendar to the more refined Gregorian variant.
Of course, the fact that this was common knowledge amongst the cognoscenti of the ancient world, long before Julius Caesar was born, is a minor inconvenient detail to today’s vainglorious, self-congratulatory calibans.


What Happens at the Equinox?


From “infoplease”:

Far from being an arbitrary indicator of the changing seasons, March 20 (March 21 in some years) is significant for astronomical reasons. On March 20, 2015, at precisely 6:45 P.M. EDT, the Sun will cross directly over the Earth’s equator. This moment is known as the vernal equinox in the Northern Hemisphere. For the Southern Hemisphere, this is the moment of the autumnal equinox.
