ANOTHER Naked Eye Visible Comet Ahead Of Christmas 2018? C/2018 V1 (Machholz-Fujikawa-Iwamoto).

Comet C/2018 V1 ( Machholz-Fujikawa-Iwamoto )

Discovered: November 7, 2018 (yes, just last week).

Discoverers: One is Arizona (Donald E. Machholz, Jr.) & two in Japan (Shigehisa Fujikawa & Masayuki Iwamoto). You can find more here. Hence the name which credits all three.


C/2018 V1 is much more of a CLASSIC comet than our current ‘Christmas Comet of 2018‘, i.e., 46P/Wirtanen. That is why it has a ‘C/’ designation while the other is a ‘P/’. The ‘P/’ denotes that 46P/Wirtanen is a PERIODIC comet — one that swings around the sun on a regular basis (like a commuter). The ‘C/’, on the other hand, means that is a NON-PERIODIC. It means that this comet has not been previously seen in the last 200-years. Typically it means that it is a FIRST TIME visitor from far, far out in the Solar System, ideally from the Oort Cloud, the incubator of most comets at the very edge of our Solar System.

So, we are assuming it is a FRESH comet, with a lot of frozen matter that will sublimate as the comet gets closer and closer to the Sun. That is what makes it visible, gives it a tail and with luck makes it spectacular. Right now it is touch and go. Viewed through a powerful telescope you can already see a blue tail — that color indicating the presence of ionized Carbon Monoxide (CO+).

On Tuesday, November 27, 2018 it will be at its closest to Earth — 62 million miles. Comet ISON (C/2012 S1) that could have been the GREAT COMET of 2013 would have been 40 million miles. So, C/2018 V1 will be 22 million miles further out. BUT, unlike ISON it will make it around the Sun. That is a given. It is NOT a sungrazer. Actually it doesn’t get very close to the Sun! As you can see from the above diagram it does not even cross Mercury’s orbit.

Right now it is BORDERLINE — but shows more promise than 46P.

I will keep you posted. This was a BIG heads up.


Comet ISON IF it had rounded the Sun — rather than getting FRIED by it, because it went so close.

There will be a fair amount of interest this year since Chanukah/Hanukkah First Night, falls on Christmas Eve.

That is special. Only the 4th time it has fallen on Christmas Even since 1900.

Chanukah/Hanukkah First Night can also fall on Christmas Day, as it did in 2005 and will again in 2024.

But, given the 8-day span of Chanukah/Hanukkah this ‘Chrismukkah’ conjunction can happen any time Chanukah/Hanukkah falls December 18th and Christmas day.

This has happened 33 times since 1900 to 2016: 1902, 1905, 1908, 1910, 1913, 1916, 1921, 1924, 1927, 1932, 1935, 1940, 1943, 1946, 1951, 1954, 1959, 1962, 1965, 1970, 1973, 1978, 1981, 1984, 1989, 1992, 1997, 2000, 2003, 2005, 2008, 2011 & 2016.

It will happen 20 times between next year and 2099: 2019, 2022, 2024, 2027, 2030, 2035, 2038, 2046, 2049, 2054, 2057, 2065, 2068, 2073, 2076, 2084, 2087, 2092, 2095 & 2098.

You don’t have to wait long. Next one is in but 3 years! 2019.

So you can see why it, viz. Chanukah/Hanukkah First Night, can and will fall on Christmas Eve (as it will in 2016), Christmas Day (as it will on 2024) or on Boxing Day (as it will on 2032).

Comet ISON Doing GREAT As It Hurtles Towards Sun — 60 Miles/Second. It Should Round The Sun OK. That Would Be Great.

Comet ISON is looking good!

It might round the Sun, i.e., perihelion, tomorrow, basically intact.

That would be GREAT for us on Earth. We will get too see it on the way back.

lacsoc31127That is Comet ISON, at right,
streaking towards the ‘disc’ obscured Sun in the middle.

I am NOT an expert at reading LASCO images (given that I don’t do it often) but check out that small RINGED object on the opposite side, Southwest so to speak. I think that that is Saturn.

SOHO and STEREO are two of NASA’s space-based Solar observatory platforms.

They are a wonderful resource with always stunning images and data.

Make use of them on Wednesday, November 27 & Thursday,
November 28 (Thanksgiving) to watch Comet ISON streak by or
INTO the Sun
— in real time.

Here, embedded in the images, are the links you will need.

Enjoy.

My money is on Comet ISON surviving perihelion mainly intact. See if I am right.
