ison on the 22/11

[JJDOBBER79]

Hi all,
Just read an article stating that ison will be 10 times brighter than it has been recently on the 22nd. Apparently doable in binos. Surely I have a chance with my 6" dob, from the dark. what does everyone think?

This is an image from Starry Night showing Ison from your location on the 22nd of Nov 2013 at 1720hrs UT (or 3:20am EST). I have not taken DST into account as we are exempt in QLD.

Ison is going to be a tough target to veiw on the 22nd. If it is sporting a decent tail you might be able to see that portion of the comet just before the Sun rises.

I have not been able to view Ison using 7x50 binos from my urban location yet. Time is running out, so if the skies are clear I will have to drive to darker skies with the scope.

Hey Stu, have a look at this. Maybe this weekend would be better?

If the skies are clear, I will be going for a drive to see it this weekend. I've got to bag this one before it becomes a Northern Hemisphere object.

Jas, ISON had an outburst last night and is now an easy binocular object.
All you need now is clear skies at 4am.

The cloud could clear by 4am. I will be getting up to have a look. I will poßt if I find it.

Hi Jas,

As Glen says, now's a good time to see ISON.

See my post here on the IIS fb page today (copied & pasted):

*HEADS UP !!!! Comet ISON is now in outburst.*

Reports are coming in saying it's now an easy catch in 10x50 binoculars (looking stellar). From a good dark site, it has been seen with the unaided eye using averted vision. Magnitude estimates are currently ranging from 6.5 to 6.1 & I'm now hearing 5.5. Ian Musgrave states that's a full magnitude jump in brightness just over this 24 hour period.

The image shown here, taken this morning by Tom Harradine from Brisbane, shows the sudden jump in brightness just within one week.

Southerners, hurry up and see it as we won't have long.
It has just two weeks to go for its November 28th perihelion. As it's now rapidly approaching the sun (the closer to the sun, the quicker they travel), means it's currently amongst astronomical twilight and low on the horizon, but fortunately these factors aren't hindering the views.

Check out Astroblogger, Ian Musgrave's blog to help you spot ISON.

Experienced comet observer, Jacob Cerny reports that strong outbursts are exceptionally rare with dynamically new comets and the one which is right now underway with comet ISON is very strong, being one of strongest outbursts recorded for this class of objects.

Sky & Telescope Magazine's John Bortle says, "Time will tell if this event is a result of a single massive release of new volatiles; the nucleus having fractured; or perhaps even a dramatic permanent, sustainable, uptick in the comet's overall brightness."

How close will comet ISON get to the the sun and will it survive?

Universe Today (Oct. 9th) says, "...researchers place the size of ISON’s nucleus in the range of 0.5 to 2 kilometres, comfortably above the 0.2 kilometre “shred limit” for its relative perihelion distance." And further adds: "ISON will pass inside the Roche limit of the Sun, which is a distance of 2.4 million kilometres (for fluid bodies) and will be subject to temperatures approaching 5,000 degrees Fahrenheit on closest approach."

Image Details: 16 exposures of 30sec through a 200mm lens and Canon DSLR this morning.

Wishing you all clear skies for some happy Comet viewing and imaging.

How far south can you be and still see it?

[cometcatcher]

Pre-perihelion anywhere south is fine. Post perihelion assuming it survives, northern hemisphere only.

Thanks for all the info. Ive been getting up early everyday to try and see it but cloud every morning. I will keep trying but time is running out. :mad2:
