Is there any hope of detecting what’s left of Comet ISON after the sun proved too much for its delicate constitution? German amateur astronomer Uwe Pilz suggest there remains a possibility that a photographic search might turn up a vestige of the comet when Earth crosses its orbital plane on January 16, 2014.

Comet ISON is located high in the northern sky near the familiar "W" or "M" or Cassiopeia during the time of orbital crossing. Stellarium

On and around that date, we’ll be staring straight across the sheet of debris left in the comet’s path. Whatever bits of dust and grit it left behind will be “visually compressed” and perhaps detectable in time exposure photos using wide-field telescopes. To understand why ISON would appear brighter, consider the bright band of the Milky Way. It stands apart from the helter-skelter scatter of stars for the same reason; when we look in its direction, we peer into the galaxy’s flattened disk where the stars are most concentrated. They stack up to create a brighter band slicing across the sky. Similarly, dust shed by Comet ISON will be “stacked up” from Earth’s perspective on the 16th.

Geminid meteor shower set to peak, but moon might curtail viewing

Dec. 9, 2013 at 6:26 PM ET

Geminid

SkyandTelescope.com
This chart shows the radiant point for the Geminid meteor shower.

This week marks the peak of what is usually considered the most satisfying of all annual meteor displays: the Geminid meteor shower.

As was the case with last month’s Leonid meteor shower, however, prospective skywatchers should be aware that once again, observers will face a major obstacle in their attempt to see this year’s Geminid performance, namely, the moon.

Unfortunately, as luck would have it, the moon will turn full on Dec. 17, and as such, will seriously hamper viewing the peak of the Geminids, predicted to occur in the overnight hours of this Friday to Saturday. Bright moonlight will flood the sky through much of that night, playing havoc with any serious attempts to observe the usually spectacular meteor shower. [See amazing photos of the 2012 Geminid meteor shower]

The Geminids are already around, having been active only in a very weak and scattered form since about Dec. 7. Geminid activity is expected to be on an upswing in the nights to come, leading up to their peak on Friday night.

Historically, this shower has a reputation for being rich both in slow, bright, meteors as well as rather faint meteors, with relatively few of medium brightness. Many Geminid meteor shower streaks appear yellowish in hue. Every once in a while, a Geminid fireball will blaze forth, bright enough to be quite spectacular and more than capable of attracting attention even in bright moonlight.

“If you have not yet seen a mighty Geminid fireball arcing gracefully across an expanse of sky, then you have not seen a meteor,” astronomers David Levy and Stephen Edberg wrote in their book, “Observe Meteors,” published by the Astronomical League.

Dark sky opportunities
The best times to look for streaking Geminids this year will be during the predawn hours several mornings before the night of full moon when the constellation Gemini will be standing high in the northwest sky.

l times in this chart are a.m. and are local standard times. “MS” is the time of moonset. “Dawn” is the time when morning (astronomical) twilight begins. “Win” is the available window of dark sky composed of the number of minutes between the time of moonset and the start of twilight.

In fact, three “windows” of dark skies will be available between moonset and the first light of dawn on the mornings of Dec. 13, 14 and 15. Generally speaking, there will be about two hours of completely dark skies available on the morning of Dec. 13. This window shrinks to only about an hour on the 14th, and to less than 10 minutes by the morning of the 15th.

Comet ISON brightens as it closes in on Thanksgiving’s solar climax

4 hours ago

Image: Composite sun image

NASA / SDO / ESA / SOHO / Helioviewer.org
A composite image, based on data from NASA’s Solar Dynamics Observatory and the Solar and Heliospheric Observatory, shows the sun and its coronal activity as well as Comet ISON approaching from the lower right.

For more than a year, Comet ISON has been taking skywatchers on a roller-coaster ride, but the most dramatic thrill is coming up on Thursday — and the prospects look good for a spectacular show.

Over the course of less than a day, the comet’s brightness “has increased by at least a factor of four, and indications are it may be closer to a factor of 10,” the NASA Comet ISON Observing Campaign reported on Wednesday.

When we last checked in with what was once called the “comet of the century,” ISON was heading toward the sun at the same time that a solar storm was pushing outward. Karl Battams, an astrophysicist at the Naval Research Laboratory who’s part of the observing campaign, was almost gleeful over the prospect that the cosmic storm cloud would interact with the comet’s tail.

However, it turned out that the cloud of electrically charged particles, also known as a coronal mass ejection, had no significant effect. “The source of the cloud is a farside active region, which is not directly facing the comet,” SpaceWeather.com’s Tony Phillips reported.

A series of images from the SOHO spacecraft shows Comet ISON approaching the sun as a solar storm sweeps outward.

Even if the outburst had swept directly over ISON, that alone wouldn’t have caused the comet to break up. However, some observers wondered whether the comet’s nucleus or tail is being disrupted. So far, the images from the Solar and Heliospheric Observatory’s LASCO C3 detector suggest that ISON is keeping it together. Mostly.

Battams reported that the comet had brightened to around magnitude +0.5, which is as bright as the star Betelgeuse in the “shoulder” of the constellation Orion. What’s more, ISON appears to be behaving like a classic sungrazing comet. That is, it’s behaving like Comet Lovejoy (C/2011 W3), which weathered its whirl around the sun and dazzled the Southern Hemiphere two years ago.

“We cannot comment on whether the nucleus is intact or not, but our analyses indicate that its rate of brightening is directly in line with that we have experienced with other sungrazing comets,” Battams wrote. “This has no implications on its chances of survival.”

Image: Finder chart

Sky & Telescope
Assuming that Comet ISON survives, here’s where to look for it in pre-dawn skies during December. The Sky & Telescope chart is drawn for skywatchers near 40 degrees latitude (Denver, New York, Madrid) but should serve for most northern temperate latitudes. The blue 10-degree scale is about the width of your fist held at arm’s length. Check SkyandTelescope.com for more charts and updates.

Battams and his colleagues on the observing campaign advised solar observatories to watch for the comet to get even brighter as it rounds the sun. They also advised casual observers not to try looking for ISON in the sky over the next couple of days, due to the risk of eye damage. (But if you’re set on trying, Sky & Telescope’s Alan McRobert provides an observing guide.)

The best bet is to monitor the comet’s passage online.

Cosmic encounter: Comet ISON expected to meet sun for Thanksgiving

euronews (in English) euronews (in English)

Published on Nov 26, 2013

A comet is heading for a close encounter with the sun later this month, and if it is not aporized or torn apart, it should be visible to the naked eye in December.

Comet ISON is expected to pass just about 621,000 miles (1 million km) from the sun’s surface on November 28.
Scientists are not sure how ISON will hold up. As it blasts around the sun, traveling at 234 miles per second (377 km per second) the comet will be heated to about 5,000 degreesFahrenheit (2,760 degrees C), hot enough to vaporize not just ice in the comet’s body,
but also rock and metal.

ISON STATUS: Much Anticipated Comet May Be In Trouble

Posted on: 2:47 pm, November 26, 2013, by

ison_comet

(CNN) — ISON, the most closely watched comet in recent years, may be falling apart as it nears its close encounter with the sun.

Comets are giant snowballs of frozen gases, rock and dust that can be several miles in diameter. When they get near the sun, they warm up and spew out some of the gas and dirt, creating a tail that can stretch for thousands of miles. Most comets are in the outer part of our solar system. When they get close enough for us to see them, scientists study them for clues about how our solar system formed.

When ISON was first discovered, hopes were high that it might become visible to the naked eye, meaning everyone might be able see it, not just those with good telescopes who took the trouble to find it. There was talk it might even rival some of the Great Comets like Halley’s or Hale-Bopp and spread a huge tail across the sky.

But some observers on Tuesday reported online that the comet is not nearly as bright as it has been in recent days and that it may be pouring out dust.

This could mean the comet’s core, or nucleus, has “completely disrupted, releasing an enormous volume of dust,” NASA’s Comet ISON Observing Campaign says in its November 25 online update.

SOLAR FLEET PICKS UP COMET ISON:

by Dr. Tony Phillips.

Because NASA’s twin STEREO probes are designed to observe the sun, they can see sundiving comets even when the glare becomes intense. Yesterday, Comet ISON joined Earth, Mercury, and Comet Encke in the field of view of STEREO-A’s Heliospheric Imager. Click on the image to view ISON’s grand entrance:

“The dark ‘clouds’ of stuff you see coming from the right are density enhancements in the solar wind, and these are what are causing all the ripples you see in comet Encke’s tail,” explains Karl Battams of NASA’s Comet ISON Observing Campaign. “I can pretty much promise you that we’re going to see ISON’s tail doing that in a couple of day’s time, but on a much larger scale!”

Battams points out another exciting development: Comet Encke and Comet ISON are converging for a photogenic close encounter. “No they’re not going to hit each other – in reality they are millions of miles apart – but as seen from the STEREO-A spacecraft, they are going to get very close!” he says. “We are probably a couple of days away from seeing two comets almost side-by-side in that camera, with long tails flowing behind them in the solar wind. To say that such an image will be unprecedented is rather an understatement.” Stay tuned for that.

Skywatchers excited as Comet ISON approaches its big day in the sun

Image: ISON view

J.C. Casado / GLORIA Project via Twitter
Comet ISON (center) and Mercury (lower left) shine in the skies over the Canary Islands’ Tiede Observatory in a photo captured at dawn on Nov. 21-22 by Juan Carlos Casado through the Instituto de Astrofisica de Canarias’ GLORIA Project.

As Comet ISON approaches its climactic Thanksgiving swing around the sun, astronomers are getting increasingly excited about the prospects for a memorable show when it comes around the other side.

“It’s looking pretty wonderful, to be honest,” Naval Research Laboratory astrophysicist Karl Battams, who’s part of the NASA Comet ISON Observing Campaign, told NBC News. “It’s behaving in terms of its brightness pretty much how we thought it would back in February.”

Comet ISON has been sparking stellar expectations ever since its discovery by Russian astronomers in September 2012. But unlike some comet fans, Battams has shied away from predicting it would turn into the “comet of the century.” Instead, he favors the saying attributed to veteran comet hunter David Levy: “Comets are like cats; they have tails, and they do precisely what they want.”

So far, Comet ISON appears to be doing what Battams and his colleagues want: It’s hanging together, and not breaking up as feared. Fresh imagery from NASA’s STEREO-A probe shows the comet in one piece — with Comet Encke’s tail waving in the solar wind as it approaches its own close encounter.

“There are some really, really nice tail dynamics going on,” Battams said.

False-color images from NASA’s STEREO mission show Comet Encke and Comet ISON in the sun-watching satellites’ field of view. Mercury and Earth are also in the picture.

Even as he gushes over the latest pictures, Battams is keeping that catlike unpredictability of comets in mind — particularly considering that ISON is due to come within only 700,000 miles (1.1 million kilometers) of the sun on Nov. 28. “My opinion this morning is, I’m starting to feel like it’s going to survive,” Battams said on Friday. “It might actually make it.”

If ISON does survive, “I’m feeling comfortable saying that we’re going to have a nice night-sky object in December,” he said.

How nice? “It was never going to be the ‘comet of the century,'” Battams said. “It’d have to be pretty good to out-comet Comet McNaught.”

Comet Lovejoy (formally designated C/2011 W3), which wowed Southern Hemisphere observers in 2011, might be a “good analog” if ISON lives up to Battams’ expectations. “It’s an educated guess,” he said.

ISON is on the verge of being too close to the sun for casual observers to make out in dawn’s skies, but seasoned skywatchers are still getting some good shots, as evidenced by the pictures submitted to SpaceWeather.com’s comet gallery.
