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

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’.

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.

Neptune, Currently Our Furthest Planet, Was Discovered This Day 171-Years Ago; September 23, 1846.

According to the lunatic fringe we are supposed to be hit by ‘Planet X’ this day — September 23, 2017. Did they realize that it was the anniversary of Neptune, the ‘Planet X‘ of its time, being discovered.

Neptune’s discovery, as I outlined it above, was pretty amazing and a testament to the cleverness of humans. Its existence was determined mathematically! That was 171-years ago. It still has me in awe.

Aren’t We Supposed To Be Hit By Planet X Today?

I just saw a Flying Pig with a flower sticking out of his belly!


This garbage and the ‘flat earthers’ who believe in it just infuriates me, no end.

If you have a modicum of understanding of basic physics or astronomy you would know that a ‘planet‘, even one as small as Mercury, couldn’t just sneak up on us with zero notice. We would see it coming, worst case 24-hours before it hits us. Planets are NOT small. And we, for the last ten years or more, have some fairly sophisticated, automated telescopic technology, around the world, funded by multiple countries, surveying and monitoring the sky for rogue objects likely to come near.

So, if we were going to be hit today, we would have known about it yesterday.

Jeez!

2017 Autumnal (Fall) Equinox In New Hampshire Will Be On Friday, September 22, 4:02pm (Eastern).

Sunrise & Sunset Times for Concord, New Hampshire around the September Equinox.
(From Time-and-Date).

Note that daylight is NOT exactly 12 hours!
If anything we get closer to 12 hours 3 days later.
There is a reason for that. It is our latitude above the equator.
If we were closer to the equator it would have been closer to 12 hours.
See this explanation in Time-and-Date.
