Yes, today, December 12th will be the earliest sunset of 2017 — in New Hampshire.

NOT the shortest day. That is the Winter Solstice on Thursday, December 21, 2017. Still 9-days to go.

But, today is the shortest evening.

There is a difference.

Sunrise and Sunset times, leading up to the Solstice, are NOT ‘symmetrical’.

Sunrise still continues to get later and later till the 21st. Then they reverse.

Check the annotated table above.

We only have 3 minutes MORE, in total, to lose. Wow.

So, rejoice. The END of these depressing early evenings.

By Christmas evenings will be a full 5-minutes later. WOW.

Two More SUPERMOONS Over New Hampshire In January 2018 — Weather Permitting.

So, as I had feared thick clouds really put a damper on Sunday, December 3, 2017’s Supermoon. I am glad I took a couple of pictures, through wispier clouds the night before.

But, all is not lost. Two more — yes, two — in January 2018. The 2nd will be a Blue Moon, the second Full Moon of a month.

The January 1, 2018 will be even closer than the December 4.

So, that is good. I will keep you posted.

Venus-Jupiter Conjunction Over New Hampshire, Monday, November 13, 2017 — Clouds & Trees!

by Anura Guruge

Clouds could be a problem. Supposed to be cloudy all day, starting early.

The conjunction will also be low-down (i.e., close to the horizon) and as such, IN NEW HAMPSHIRE, could be obscured by our trees, even if they don’t have any leaves anymore.

I did a post on Edmond Halley (29 October 1656 to 14 January 1741 (new Gregorian calendar)), on the anniversary of his death, on January 14, 2017.

So, I am not going to repeat myself. {Smile}. Instead I am giving you the above two YouTube videos, which are good, and the Wikipedia entry.

OK?

But, please check my earlier post. You will be glad that you did.

A/2017 U1 — Too Speculative To Claim That It Is ‘Interstellar’.

by Anura Guruge

Definitely extremely interesting and intriguing. Wow. Orbital eccentricity of 1.1922! The greatest we have ever seen — the keywords here being ‘ever seen’. Comet ISON, that crashed and burned on Thanksgiving Day 2013 had an eccentricity of 1.0000015.

But, here is the deal with eccentricity. Anything over 1.0 means that the object will eventually leave our Solar System. That we know. But, what we cannot tell as yet is WHEN A/2017 U1 got that highly eccentric orbit. We just do NOT know — as yet. And maybe never will.

To claim that it must have originated OUTSIDE of our Solar System — is speculative. We do NOT have enough evidence.

NASA/JPL’s official statement confirms that: “So far, everything indicates this is likely an interstellar object, but more data would help to confirm it.” Note the ‘likely‘ and the part about ‘more data … for confirmation‘. That is exactly MY POINT and what I am trying to impress.

The claim that its orbit was NOT influenced by a close encounter with a planet — typically one of the BIG ones — is speculative. It could have been majorly torqued around by Uranus or Neptune. We don’t know.

I have a druthers that this is a very old comet — a periodic one at that, which on its last trip out, maybe 400 years ago got too close to a gas giant and had its orbit turned ‘upside down’.

We don’t know.

All I am stressing is do NOT jump to conclusions.

We know so little about what has happened in OUR Solar System and what is happening right now.

But, it is exciting.


Has a ton of good information about comets.
