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

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.

Two Comets to Fly By Mercury

science.nasa.gov

Nov. 15, 2013:
“This is a unique coincidence,” says Ron Vervack an astronomer at the Johns Hopkins University Applied Physics Lab and a member of the science team for NASA’s MESSENGER spacecraft, “and a golden opportunity to study two comets passing close to the sun.”

On Nov. 18th Comet Encke will pass within 0.025 AU of Mercury, followed a day later by Comet ISON at 0.24 AU (1 AU is the distance between the sun and Earth, 150 million km).   The MESSENGER spacecraft, which is orbiting Mercury, will turn its sensors toward the passing comets for a point-blank investigation of both.

The double flyby is exciting, says Vervack, but “it makes things a little crazy. We have to rush to complete our observations of Comet Encke, then do it all over again for Comet ISON. Everything is happening at more or less the same time.”

MESSENGER was designed to study Mercury, not comets, “but it is a capable spacecraft with a versatile instrument package,” he adds. “We hope to get some great data.” Onboard spectrometers will analyze the chemical makeup of the two comets while MESSENGER’s cameras snap pictures of atmospheres, jets and tails.

Comet ISON is already a media favorite. Astronomers have been tracking it since Sept. 2012 when it was discovered on a trajectory that would take it perilously close to the sun.  On Nov. 28th of 2013, Thanksgiving Day in the USA, Comet ISON will pass through the sun’s atmosphere little more than a million kilometers above the sun’s fiery surface.  If the icy comet survives, it could emerge as a beautiful naked-eye object for observers in the northern hemisphere.  MESSENGER’s glimpse of Comet ISON as it plunges inward could give astronomers the data they need to predict the comet’s fate.

Comet Encke is less well known, but no less interesting.  For one thing, it is the source of the Taurid meteor shower, a slow display of midnight fireballs that occurs every year in early- to mid-November. Comet Encke dips inside the orbit of Mercury every 3.3 years, so it is regularly exposed to solar activity.  In 2007, NASA’s STEREO spacecraft watched as a solar storm ripped off Encke’s tail–which promptly grew back: movie.

“We’ll be catching Comet Encke just days before its closest approach to the sun (0.3 AU),” Vervack  says, “so we get to see it at its most active.”

Ironically, the fact that MESSENGER is designed to study a rocky planet could prove advantageous for the icy comets.  MESSENGER’s x-ray spectrometer, in particular, could detect signs of ‘comet dirt’.

“We hope to obtain the first definitive detections of x-ray emissions from silicon, magnesium and aluminum,” he explains. “If you think of a comet as a dirty snowball, these are elements that make up the dirt.  Close to the sun is where we expect the dirt to be vaporized.”

In total, Vervack expects MESSENGER to gather 15 hours’ worth of data on Comet Encke and another 25 hours on Comet ISON.  With that kind of observing time, discoveries are a distinct possibility.

Vervack says the first images will be beamed back and released to the public within days of the flybys.  “There are no guarantees,” he cautions, “but I can’t wait to see the pictures.”
