A solar eclipse in which the moon passes between the sun and us.  Those of us in California will see a partial eclipse.  If you wish to see a total eclipse, head on up to Salem, Oregon.

Never look directly at the sun without appropriate eye protection. One way to safely view an eclipse of the sun including direct viewing is with eclipse glasses. Eclipse glasses are available from Amazon from about $8.00 to $18.00; also from Walmart online.

Supermoon

supermoonIf you wish to make an apple pie truly from scratch, you must first invent the universe. — Carl Sagan

Supermoons, most of us can’t detect the difference between a supermoon and a regular full moon, using just our eyes. Finely tuned instruments or composite images do show that a supermoon is indeed closer to Earth and thus bigger than an ordinary full moon. Therefore, if we can’t see that a supermoon actually appears larger in the sky, we notice the increased brightness of the supermoon.
Supermoons bring the highest and lowest tides, they follow the date of full moon by a day or two.

The supermoon event happens Sunday November 13 and Monday the 14th.
The best time to observe the supermoon is when the moon is near the horizon during either moonrise or moonset; allegedly, Monday is best. …

Sunday Evening, Nov. 13 — Moonrise — 4:47 pm
Monday Morning, Nov. 14 — Moonset — 6:42 am
Monday Evening, Nov. 14 — Moonrise — 5:34 pm
Tuesday Morning, Nov. 15 — Moonset — 7:54 am

In the beginning the Universe was created. This has made a lot of people very angry and has been widely regarded as a bad move. — Douglas Adams
