[meteorite-list] Big Sun-diving Comet Discovered: Comet C/2012 S1 (ISON)
Space Weather News for Sept. 25, 2012 http://spaceweather.com SUNDIVING COMET: Astronomers are paying close attention to a newly-discovered comet, C/2012 S1 (ISON), which is heading for a remarkably close encounter with the sun. Fierce solar heat could turn Comet ISON into a bright naked-eye object in Nov. 2013.

Hi Ron/List, Given the length of the current arc (270 days), and the consistency of the photometry over that time, I will go out on a limb and say that this will almost certainly become the brightest comet that has ever been seen -- by a significant margin -- by most people alive today. What's particularly amazing is how close this comet will come to Mars around October 1st next year -- less than 7 million miles! Hopefully NASA/JPL will have plans in the works to schedule instrument pointing and imaging of the comet using the suite of sensors both on and in orbit around the Red Planet. For Mars, this will be a northern hemisphere comet -- certainly visible from both rovers. --Rob -Original Message- From: meteorite-list-boun...@meteoritecentral.com [mailto:meteorite-list-boun...@meteoritecentral.com] On Behalf Of Ron Baalke Sent: Tuesday, September 25, 2012 8:57 AM To: Meteorite Mailing List Subject: [meteorite-list] Big Sun-diving Comet Discovered: Comet C/2012 S1(ISON) Space Weather News for Sept. 25, 2012 http://spaceweather.com SUNDIVING COMET: Astronomers are paying close attention to a newly-discovered comet, C/2012 S1 (ISON), which is heading for a remarkably close encounter with the sun.

Given it might be as bright or brighter than the full Moon, what size will it appear, comparatively speaking?? -- * Stuart McDaniel Lawndale, NC IMCA#9052 http://spacerocks.weebly.com http://www.facebook.com/Stuart.McDaniel.No.1 * Matson wrote: = Hi Ron/List, Given the length of the current arc (270 days), and the consistency of the photometry over that time, I will go out on a limb and say that this will almost certainly become the brightest comet that has ever been seen -- by a significant margin -- by most people alive today.

Re: [meteorite-list] Big Sun-diving Comet Discovered: Comet C/2012 S1(ISON)
Some early estimates are that close to perihelion, the comet's tail could span more than 90 degrees as seen from earth. Haven't read any estimates yet on the expected angular size of the coma surrounding the nucleus. Probably no way to predict since the composition and size of the nucleus are not known. --Rob -Original Message- From: actionshoot...@carolina.rr.com [mailto:actionshoot...@carolina.rr.com] Sent: Tuesday, September 25, 2012 11:02 AM To: Ron Baalke; Meteorite Mailing List; Matson, Robert D.

Wow...looking forward to that if predictions are true.

Re: [meteorite-list] Big Sun-diving Comet Discovered: Comet C/2012 S1(ISON)
There is always the possibility of an unexpected outburst. Just a few years back, we saw that with comet Holmes (2007 or 2008?). That comet provided a lot of great observing for weeks before it faded and nobody saw that outburst coming. Under moderately bright urban skies, Holmes achieved naked eye visibility. This new comet could put on a similar show. -- - Web - http://www.galactic-stone.com Facebook - http://www.facebook.com/galacticstone Twitter - http://twitter.com/GalacticStone Pinterest - http://pinterest.com/galacticstone RSS - http://www.galactic-stone.com/rss/126516 - On 9/25/12, Matson, Robert D. robert.d.mat...@saic.com wrote: Some early estimates are that close to perihelion, the comet's tail could span more than 90 degrees as seen from earth.

Yes, this COULD be a real beauty but let's not forget we've been fooled before. Definitely worth keeping an eye on but let's not get our hopes TOO high just yet. After all they CAN and are often unpredictable. Regards!
