Comet ISON Disintegrates

We held out hope that Comet ISON not only made it around the Sun intact but that it would offer a spectacular December view.  Much to everyone's dismay it now appears that Comet ISON has finally met the end.

The Comet was once thought to be lost on Thanksgiving Day as it passed very close to the Sun only to come into view gain and brighten as it went.  This left hope that the comet might be able to make a showing for eager observers throughout the world.  As of this morning, it now looks like the comet has gone complete dim and may have completely disintegrated.

My attempt at observing the comet early the morning of November 30th and December 1st were both uneventful and given that reports currently put the comet beyond naked-eye magnitude (6.5+) it is unlikely that much of this comet remains.

The view from the SOHO satellite shows it passing through a jet of material ejected from the Sun and beginning to fade substantially after that.  The image below is courtesy of NASA/ESA/SOHO.  As you can see in the upper right corner of the picture, the fuzzy smudge is what remains of Comet ISON.


In the event that something changes, I'll be sure to send out another update with that new information.  Beyond that, this will be the final update on Comet ISON.

It should be noted that if you have a set of binoculars or telescope there are still a few comets strolling through that are still visible.  The main one being Comet Lovejoy which is still visible with  off the handle of The Big Dipper (Ursa Major) near the top of the constellation Bootes starting at around 3:00 AM.  Comet Lovejoy should be visible approximately 1 degree lower in the sky than the star Nekkar which is the top star in Bootes.

Below is a sky chart which may provide helpful information on locating Comet Lovejoy the morning of December 2nd at the time it rises.


Comet ISON Viewing for December 1st

Viewing of Comet ISON should begin to be possible for U.S. observers beginning tomorrow morning.  See below for chart images that may provide additional help in locating the comet.

You'll be looking for a fairly bright object in the Eastern sky right before dawn.  From experience, I recommend being outside with a very clear view to the Eastern horizon about 15 minutes before the comet is ready to come above the horizon.  The first thing you'll probably see is the Sun lighting up airplane contrails as it gets closer to rising.  Don't mistake these for comet tails!  Comet ISON (even though it's traveling away from the Sun) will look like it's pointed at the sun (tail shooting up into the sky toward the zenith.

For the midwest (and probably transferable to the rest of the U.S.) you should expect the comet rise time to be around 6:40 AM local time.  Since it will cross the horizon at that time, I would expect it to become visible sometime between 6:55 AM and 7:10 AM local time.  Comet ISON should be about 7 degrees above the horizon at around 7:20 AM local time.  Keep in mind, this may vary due to any number of factors of your locale but should be close.  If you've not seen the comet by around 7:25 AM local time, there's a good chance it's not going to be visible as the Sun's brightness will drown out the ability to see ISON.

I have added two images from Stellarium which show the sky configuration at 6:39 AM and 7:20 AM respectively.  I have also added the latest pictures of the Moon, Jupiter, Mars and a sunrise to the album for November 29th.

Comet ISON Morning Observing and Lovejoy Update

See below for November 30th observing information:

Comet ISON has made it around the Sun at least partially intact!  This is great news for those who are looking for an opportunity to see this comet.  The current magnitude is almost -1 which means it should be easily visible to the naked eye as it comes back around the Sun to be visible once again in the morning skies.

On November 30th, you may be able to see the comet if you're up early enough.  The comet is set to rise starting at 6:55 AM CST in the Northeast sky (see graphic for coordinate information) and may be visible up to just before the Sun rises at 7:26 AM CST.


It is not yet known how long the comet will remain viable.  There were some concerns that it might not even make it through the approach.  Especially (as can be seen in my previous post of SOHO images) since the comet showed some active disintegration and disappeared for a bit on it's way around the Sun.  There is an expectation that better information about the comet, and how stable it really is, will be coming out over the next few days as more observations are able to take place.

In the mean time, I took the liberty of doing a little bit of astrophotography this evening with my Nikon D80, 70-300mm telephoto lens and a tripod.  While this is certainly not an ideal setup, it still manages to capture a few shorter exposure shots well enough.  I had two goals with this outing, the first was to see if there was any way to snag comet ISON this evening after sunset since the Sun set prior to the comet.  Alas, this was a bunk effort not only due to the bright sunset but because of low clouds in the Western sky.  Even so, those clouds made for some very nice sunset photos (see gallery).

The second goal was to see if I could capture Comet Lovejoy.  This comet has gone from naked eye visibility in mid-November to binocular, telescope and photo visibility at this point running around the 7-8th magnitude for right now (it's only going to get dimmer from here).  I pointed my camera at roughly the spot where I expected it should be and started snapping a couple pictures.  Unfortunately, my electronics weren't working well tonight and I wasn't able to look up the exact position of the comet and get better pictures while zoomed in.  But, to my surprise, I DID snag some faint shots of it without any zoom.  While these shots are very clearly not very good, the accomplishment is that something was obtained.  One other thing to note is that aircraft were everywhere tonight and interfered with several of the shots that I kept.

Happy comet viewing everyone!  Keep checking in for updates, I will post more as I have them.

Comet ISON C/2012 S1 Thanksgiving Comet

See full article for images and after Thanksgiving sky location for Comet ISON.

Finally, the heavens clear and the Sun appears.  Too bad for me it's a day or two late to capture final pictures of Comet ISON before it passed out of visual range.  Right now the comet is on it's way around the Sun and is too close to be visible until after Thanksgiving.  Fortunately for you, I've found a few pictures of ISON to share which dwarf anything I'm currently capable of providing on my own.

Including current pictures of the comet's approach to the Sun via the SOHO satellite

And the the most spectacular shot I've seen to date.  This has so much stunning detail it looks like a painting.  Taken by Damian Peach ( on November 15th 2013.  This picture was captured using the following settings and equipment: 0.11m F5.6 STL-11k camera. LRGB: L: 5x2mins. RGB: 1x2mins.


November 29th, 2013

Viewing the day after Thanksgiving will still be a formidable challenge because (assuming the comet survives the trip around the Sun) ISON will still be very close to the Sun angularly.  You'll want to look very close to the horizon where the Sun set after sunset about 4:45 PM to 5:00 PM local time.  At this time the Sun will only be a few degrees below the horizon and ISON will only be a few degrees above it.  This also means that you'll need an extremely good Western vantage point.

The picture below provides a rough idea of where the comet will be with respect to the Sun.  The blue line represents the horizon line.  Keep in mind this picture does not take into consideration horizon obstructions such as buildings and trees or any atmospheric problems such as the sky being too bright or overcast.


December 1st, 2013

By Sunday, the comet will be a little bit further away from the Sun and should provide an easier sight.  While the comet will continue to be an early evening object (which is great for anyone who's not a night owl) it should be a naked eye sight through the first several weeks in December, depending on brightness, maybe longer.  You will still find it best for observing the comet if you find a clear sight with a vantage point that gives you an unobstructed view of the Western horizon.  Continue to look for it in the very early evening sky right after sunset.

Happy Thanksgiving and happy viewing!  Keep an eye out for updates on this as the comet swings around the Sun.

Comet ISON Late November Update

Unfortunately for me, Comet ISON has been extremely elusive. Inclimate weather has been passing through the midwest leaving only a few days where observing might have been possible, albeit with low temperatures. I made one serious attempt to capture a glimpse of the comet and photograph it using my 6" refractor but unfortunately the outting was riddled with technical problems and yielded nothing more than very cold hands.

However, the comet still holds serious promise…

As you can see by the chart included below (courtesy of Skymania), the comet is getting closer and closer to the horizon for it's Thanksgiving rendesvous with the closest approach to the Sun that it will make. While the comet is ellusive, if you get the opportunity to be up an hour to 30 minutes before dawn with clear skies over the next several days you may be able to catch a glimpse of it with the naked-eye near where sunrise will occur.  You should look for a fuzzy, bright, tail pointing straight up towards the zenith.


This comet is special in a couple of ways.  The first is that it came from the Ort cloud, a group of comets and various debris left over from the formation of the solar system.  This area is 2,500 times further away from the Sun than Pluto which means it started traveling toward the Sun over a million years ago!  This also means that it won't be back anytime soon, probably ever.  Now, assuming the comet makes it around the Sun over Thanksgiving, which is not certain right now, there is expected to be some spectacular viewing of it between Thanksgiving and Christmas as ISON begins its very long journey out of the solar system.

Keep an eye out for pictures and updates on the comet.  I'll be posting relevant information and pictures as I take them.
