Operation: ISON Barycentrism for Comet ISON enthusiasts

[Dark Neptune]

Hi,Vincent
Yes,in fact I sincerely hope more money being spent on research than today's situation--more and more spent on military hardware research to kill people and enhanced killing techniques like neutron bombs,drones,germwarfare,chemical weapons etc.For example--to the arguments of drainage systems on mars by marsians;its quickly resolved by a few space probes that there is no marsians.
In fact,arguments in the scientific areas lead to more advancement;more experiments;people building /thinking out more advanced equipment to test their ideas and hence REAL progress.In fact,I think,if we dont have all these wars,we would have landed on mars and living on the moon.sigh. In the meantime,lets enjoy the day and night sky.Thanks.

Hello once again superiorstream,

I am very much on the same frequency as you on that pacifist view.

How has the Sun been these past few days? Any notable observations?

[Dark Neptune]

yeah, how about we wait for the comet to swing by, observe put all the data together n see what we can learn from that

Hello bornfree, and welcome to the O:IB thread!

Yes, of course! That is part of the O:IB plan indeed. In the meantime, you can continue to digest the contents of O:IB in this thread and post your inquiries about it, as we await for November 28 2013.

Cheers!

Hi,Dark Neptune
Well,the sun had been quiet and at its minimum;which occurs 15 days late.Now its mini-cycle is 8 1/2 months--lets see how long the next one last or is it a complete break-away from this pattern.Anyway,expect at least a slight up in activities in the coming days--or it may give us a surprise with a hugh outburst in the next cycle.Well the sun is always unpredictible and interesting.Thanks.

Hello superiorstream,

Thank you for the update! Anything other future interesting solar activity, hope you can share it with us here. There can be solar activities that may indirectly help us to better expect what we could possibly see when comet ISON approaches near the Sun.

This is a great site for up-to-date images of Comet ISON. (And the occasional C/2013 R1 Lovejoy and 2P/Encke.) Enjoy people. ^_^

Expect good news from the spacecrafts currently orbiting Mars 2 weeks later on ISON. And also, ignore the article title's misuse of the term "sundiving comet". Should have been sungrazing comet instead.

"NASA’s Interstellar Boundary Explorer (IBEX), a $169 million spacecraft has discovered what many scientists surmised; the sun has a comet-like tail." - SPACE, July 11, 2013

And reportedly, by looking straight down the heliotail, its structure formed with fast and slow winds that shaped like a four-leaf clover, was slightly rotating and not centered to the Sun.

Back in the 20th century, there was a “Comet of the Century” known as Comet C/1965 S1 Ikeya-Seki, and the image of this sungrazing comet was successfully captured when it was very near the Sun.



The above image was taken from the Norikura Solar Observatory’s coronagraph, which used an occulator to block the direct light from the Sun for observing Comet C/1965 S1 Ikeya-Seki.

Reportedly, this photo of Comet C/1965 S1 Ikeya-Seki was taken by F. Moriyama and T. Hirayama (Tokyo Astronomical Observatory, Mitaka, Japan) at the Norikura Corona Station on 1965 October 21 before 12pm local time in Japan. They used a 12-cm coronagraph and Fuji Panchroprocess plates behind a Mazda VG1B color filter. This was a 4-second exposure.

"A coronagraph is a telescopic attachment designed to block out the direct light from a star so that nearby objects – which otherwise would be hidden in the star's bright glare – can be resolved." - Excerpt from Wikipedia on "Coronagraph"

[Vincent_WF]

The image illustrated below is an artist's concept of the heliospheric current sheet, and this field was observed to extend throughout the Sun's equatorial plane in the heliosphere.



Apparently, the spiral field of the heliospheric current sheet rotates cyclonically with the Sun in tandem with the direction of the planetary orbits.

Lately there were reports that the luminosity of Comet ISON did not increased as it was hoped, and therefore suggested this comet might be another spectacular dud like Comet Kohoutek, which fell far short of expectations.

While Comet Kohoutek has a cyclonic trajectory around the Sun that had move more in tandem with the heliospheric current sheet of the Sun, Comet ISON has an anti-cyclonic trajectory. These can be verified with the JPL browser.

And being a sungrazing comet that would be more than ten times nearer to the Sun at perihelion as compared with Comet Kohoutek, the magnitude of force with effects of inverse square laws at close proximity would thus subject the coma of Comet ISON to tremendous pressure with its anti-cyclonic trajectory. And therefore it is not unrealistic to expect this comet to spectacularly flare up when it gets near the Sun.

Of course this is merely a two cents worth speculation with the comparison of some significant differences of the two comets.

Hi Vincent. Thanks for sharing your views. So much science can be done with just one comet!
