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.

All these pictures (bar the first two) were taken by Devanee Guruge.

Alton photographer, John Bishop, a friend, who arrived and joined Devanee in taking pictures. So I had two tripods with cameras at the back.


It wasn’t packed but the folks that were there were very receptive and engaged. I had planned for about 90 minutes but we were still there, having a lot of fun, 2 hours later. They seemed to really like it — or at least that is what they claimed.

I had fun. But, I have never done a presentation where I have not had fun.

Our friend, Alton photographer, John Bishop, turned up — unexpectedly given that we thought we was going to be in Manchester visiting a friend that was in hospital. John set up his, professional grade Canon, and started taking pictures in tandem with Devanee — who relished the opportunity to use my Canon. I should get John’s pictures on Sunday.

Part II of this astronomy presentation is on Friday, November 20, 2014. You can come to that even if you didn’t come to last night. They are self-contained, though I will not go over the same material.

So that was that. I am glad that I did it.

Holly Brown, the librarian, always extremely nice, had displayed my astronomy books on a table etc. She was very happy, and that was good.

Click image IF you want to download a 3.2MB Adobe Acrobat PDF of the slides. I tried to keep the transitions to a minimum so that most of the images will appear in the PDF. But, I am so used to using animation that I did NOT succeed entirely — though, I think, this is the BEST I have ever done. So IF some slides don’t make sense or they look incomplete is because there are OVERLAY transitions [i.e., animations] that don’t make it to the PDF. Sorry.

This relates back to my ‘Comet ISON‘ presentation at the Gilman Library last November. It went well, was reasonably well attended and, most of all, well received. Holly Brown, the librarian, was very pleased.

Since then I have kind of become a de facto local ‘expert’ on all things to do with the skies. So when they received this telescope in the Summer she asked me to have a look at it and see if there was anything I could do to kind of kick it off.

These two presentations, which were supposed to have been in September & October, but are now in October & November are the outcome of those conversations.

I haven’t had the time to actually use this telescope. I have, however, told a number of kids to borrow it from the library.

Peering through telescopes is no longer my thing. Which is why we are down to just one telescope at home. With my eyesight and time constraints I am much better off looking at images on the computer. And ironically that is what professional astronomers do. But, I am all in favor of kids exploring the skies with a telescope. So I am very glad that we have this cute little telescope at the library.

Now I have to start thinking about putting together a presentation for October 17th. It should be fun. So much I could cover. The sky is the limit.

A couple of weeks ago I needed some flowers delivered to a patient at Dartmouth Hitchcock Medical Center (DHMC) in Lebanon.

I had no idea as to who could do this. So I just called up the DHMC switchboard and asked them. They must get quite a few of these calls since they gave me the answer right away.

They told me that they no longer had a florist ‘in house‘, but the florist that was there was the ‘Garden of Eden‘, in Lebanon, and that I should call them. They gave me their phone number, viz. 603-448-6000.

I checked them out on the Web. Seemed reasonable and decent. I called. Very helpful. Very nice. I placed an order.

It was delivered that afternoon. I gather it was a very impressive and pleasing arrangement. So I was glad. Money well spent.

So a call out for them.

If you need flowers sent to DHMC or Dartmouth College or thereabouts … call them.
