C/2008 Q3 Garrad's amazing journey

Comet C/2008 Q3 Garrad near Centaurus A (NGC 5128), click to embiggen

Comet C/2008 Q3 Garrad is in outburst. This comet should be very faint, around magnitude 12-13 (and is still listed as such in the MPC ephemeris), but is currently around magnitude 8. Well within the reach of modest telescopes and, if you have good eyesight and are in a dark sky location, 7x50 and 10x50 binoculars. Due to a variety of factors (like cloud and an inconvenient Moon), I haven't been able to see Q3 Garrad in binoculars yet.

Which is disappointing, as the comet has been traversing some really beautiful territory. It has been near the stunning globular cluster Omega Centauri, globular cluster NGC 6362 and the galaxy Centaurus A recently. However, I was able to use the Global-Rent-a-Scope system to image C/2008 Q3 Garrad near NGC 6362 and Centaurus A.

Comet C/2008 Q3 Garrad and globular cluster NGC 6362. Click to embiggen.

Sadly, the Rent-a-scope system was clouded out when I wanted to image Omega Centauri. The images you see were taken with the widefield G12 using a 90 second 1x1 binned exposure with luminance filtering. I also took a RBG colour series of the Centaurus A encounter, but I have been unable to assemble the images into something worth while yet (anyone who has experience with Global Rent a Scopes RBG images and Image J, please contact me).

The comet is now in a quieter part of the sky, However, it will come within 3 degrees of globular cluster M68 between 21-23 June. If you would like to look for it it, there is a spotters map to the left, click to embiggen and print, and a PDF format binocular map is here.

Other images of C/2008 Garrad are here, here, and a stunning colour picture of the comet near Centaurus A by Rob Kau is here and another here.

Comet C/2009 P1 Garrad, September 20 and 22


Left Image: Comet 2009 P1 Garrad on 20/9/2011. Right Image: Comet Garrad on the 22/09/11. Click to embiggen. Comet C/2009 P1 Garrad imaged using the Global-Rent-a-Scope GRAS-05 instrument.

The left image was done from 120sec luminance RGB filers at 1x binning, the right luminance 120 sec 2x binning and RGB 60 secs with 2x binning. Images stretched with FITS-Liberator, aligned and cropped in ImageJ then luminance and RGB channels assembled in the GIMP, with a little contrast enhancement.

Not as good as Rolando Ligustri's image using the same exposure and binning on the GRAS-11 instrument. I still have a lot to learn about colour image processing.

The Sky This Week - Thursday October 27 to Thursday November 3

The First Quarter Moon is Thursday November 3. Venus is easily visible in the western evening twilight with Mercury below it. The Moon joins Venus and Mercury on the 28th. Jupiter now dominates the evening sky and is at opposition on the 29th. Mars is visible in the morning sky nearing the star Regulus . Comet C/2009 P1 Garrad is visible in binoculars in the north-western sky.

Morning sky looking north-east as seen from Adelaide at 5:30 am local daylight saving time on Sunday October 30 showing Mars and the brighter stars. Similar views will be seen elsewhere at the equivalent local time. Click to embiggen.

The First Quarter Moon is Thursday November 3.

Jupiter is at opposition, when it is biggest and brightest as seen from Earth, on Saturday the 29th. Jupiter is visible all night long now.

In the morning Jupiter low is above the north-western horizon.

In the evening Jupiter is readily visible in the north-eastern sky, from about 7 pm local time on. Now is a good time to begin telescopic observation of this massive world, or follow its moons in binoculars. For good telescopic observation Jupiter is best from 10 pm - 1 am. Although it is biggest and brightest on the 20th, Jupiter will be excellent viewing for a couple of months now.

Mars is low in the north-eastern morning sky, in the constellation of Leo. Mars comes closer to the bright star Regulus over the week.

Comet 45P Honda is in the morning sky, but will be very hard to see in the twilight sky without a decent telescope.

Saturn is lost in the twilight glow.

Bright white Venusand Mercury are now readily visible in the evening western twilight sky from around half an hour after sunset for somewhat over an hour.

Mercury is visible below Venus at the beginning of the week, and becomes more prominent, and closer to Venus, as the week wears on. Both planets climb higher in the evening sky over the week. On the evening of Friday the 28th, the thin crescent Moon is close to the pair, making excellent viewing.

ALthough Jupiter is the most prominent now, there are lots of interesting things in the sky to view with a telescope. If you don't have a telescope, now is a good time to visit one of your local astronomical societies open nights or the local planetariums.

Comet C/2009 Garrad is visible in binoculars in the north-western sky, in the constellation of Ophiuchus.

Although it has brightened substantially, it is still only a fuzzy dot at magnitude 6.5. The best views will be under dark skies, where you might spy a short faint tail.

The best viewing is just before 9:00 pm, when the sky is dark enough to reveal the comet and it is not too close to the horizon. This will be the last week the comet will be easily visible, before it comes too close to the horizon for viewing. It will enter the morning sky in November.

Although it has brightened substantially, it is still only a fuzzy dot at magnitude 6.9. The best views will be under dark skies, where you might spy a short faint tail. The best viewing is around 8:00 pm, when the comet is almost due north and highest in the sky. Early in the week the comet will be hard to see due to Moonlight, but by the weekend the skies should be dark enough to pick it up easily.

The New Moon is Thursday October 27.

In the morning Jupiter low is above the north-western horizon.

In the evening Jupiter is readily visible in the north-eastern sky, from about 9 pm local time on. Now is a good time to begin telescopic observation of this massive world, or follow its moons in binoculars. For good telescopic observation Jupiter is best from 10 pm - 1 am.

Mars is low in the north-eastern morning sky, in the constellation of Leo. Mars nears the bright star Regulus over the week. On the morning of Saturday, October 22, Mars and the waning Moon are close together.

Comet 45P Honda is in the morning sky, but will be very hard to see in the twilight sky without a decent telescope.

Saturn is lost in the twilight glow.

Bright white Venus is now is now readily visible low in the evening western twilight sky from around half an hour after sunset for somewhat over an hour.

Mercury is visible below Venus at the beginning of the week, and becomes more prominent, and closer to Venus, as the week wears on. Both planets climb higher in the evening sky over the week.

There are lots of interesting things in the sky to view with a telescope.If you don't have a telescope, now is a good time to visit one of your local astronomical societies open nights or the local planetariums.

Comet C/2009 Garrad is visible in binoculars in the north-western sky, in the constellation of Ophiuchus.

Although it has brightened substantially, it is still only a fuzzy dot at magnitude 6.5. The best views will be under dark skies, where you might spy a short faint tail.

The best viewing is around 9:00 pm, when the sky is dark enough to reveal the comet, even thought it is coming closer to the horizon. By the end of the week the window for observing the comet is narrower.

A chart showing C/2009 P1's location is here.

The location of the Orionid meteor radiant (yellow cross) as seen looking north-east at 3:00 am October 23 local daylight saving time from Adelaide. Similar views will be seen at equivalent local times elsewhere.

The Orionid Meteor shower peaks on October 22 at 13h UTC, (around midnight AEDST) in Australia, the radiant for the Orionids rises around 1 am on October 23, with the best meteor viewing being between 3:00 am and 4:00 am. You can expect to see roughly a meteor every 5 minutes or so under dark skies.

As the name suggest, the meteors will seem to originate just below Orion. Allow several minutes for your eyes to adjust to the darkness and be patent, it may take ages for a meteor to turn up, then you may see a few in a row.

You can use the Meteor Flux Estimator to predict the number of meteors you might see at your location. Choose 8 Orionids, and make sure the date is 2011 and you have DST on if you are in daylight saving zones.
