Space Weather News for Nov. 16, 2013 http://spaceweather.com
COMET ISON UPDATE: Comet ISON is now ten times brighter than it was on Nov. 13-14 when an unexpected outburst propelled the sundiver into the realm of naked-eye visibility. Observers around the world confirm seeing the comet as a faint smudge low in the eastern sky before sunrise. Backyard telescopes reveal a riot of gaseous streamers trailing behind the comet's brightening (and possibly fragmenting) core. With almost two weeks to go before ISON plunges into the sun's atmosphere, it is already one of the most beautiful and active comets in years. Current images and observing tips may be found at http://spaceweather.com.
Patrick, the eastern horizon is pretty high from SPOC. Will you be able to see it before the sky gets too bright? On Sat, Nov 16, 2013 at 3:20 PM, Wiggins Patrick <paw@getbeehive.net> wrote:

Any luck, Patrick? My bed felt too good this morning and I actually slept-in until well after sun-up. It's been ages since I've slept so late. I have to get up at 4 AM tomorrow so I'll give the comet herd a look then. Too bad the moon is compromising imaging for a while. Hopefully ISON holds together after perihelion.

I can't say at this point. But I hope to find out in the morning.

I tried for ISON again from work, with a clearing in that direction, still no luck. ISON is practically right on top of Spica this morning and is lost in the bright star's glow.

Chuck - if that link doesn't work you're not missing much - just a green blob below Spica. I was convinced ISON would be invisible now, with the clouds and moon and being so low in the sky as it starts to lighten. I was pleasantly surprised to see it in the photos right where it should be. This makes me want to try to find a place with a clear view of a flat eastern horizon to see how it looks earlier in the morning. (Is there such a place within an hour or two of the Salt Lake valley?) The last time I saw it with my eyeball it was pretty vague. All this talk of 6x brightness, ISON wakes up, etc. makes me want to have another go before it plunges to the sun.

The coma is pretty bright from the photos I've seen lately, Dion, so even if the moon washes out the tail, that at least should be an easy pick. I've always had good luck imaging morning comets from Little Mountain. It's been a few years since I was last up there, and headlights from the road can be a problem, but the eastern horizon is nice and low. Kurt Fisher reports that the lights of Jeremy Ranch have contributed to a bit of glow in recent years. But it's nice and close and you might have to drive over an hour to better it. I'm keeping my fingers crossed that the comet holds together after perihelion, sporting a much longer, brighter tail. The moon will be out of the picture by then, as well.

It is reported the tail is 7 degrees now, the question is how much of it survives as it passes the sun.

Thought it was nearer to Regulus.

It's moving very fast right now, Erik. Perihelion is only a little over a week away, IIRC. With the moon in the sky, the optimum imaging window has passed until after perihelion, if it survives. Visual observing is still possible, though compromised by moonlight. It's also getting lower every morning. On Mon, Nov 18, 2013 at 9:02 AM, Erik Hansen <erikhansen@thebluezone.net>wrote:

Here are the finder charts I've been using for ISON & Lovejoy: http://media.skyandtelescope.com/documents/Comets_Ison_Lovejoy_LateNov.pdf
My understanding is it disappears for few days, I am waiting until it reemerges from the sun before I interrupt my dogs beauty sleep or is that mine.

Cloudy again here in Stansbury this morning. A friend who flies for Southwest said he looked for it from high above the clouds and artificial light pollution this morning but could not see it. patrick On 18 Nov 2013, at 06:09, Chuck Hards wrote:

ISON was practically right on top of Spica this morning. I'm not surprised that he couldn't see it, even at 30 or 40 thousand feet. It would have been lost in the star's glare, visually, with bright moonlight doing as much damage as strong light pollution.
