    New comet: c/2012 k5 (linear)

    Because I don't like to highlight objects in "Eyes on the Sky" videos I have not seen myself, I generally don't include things like comets where I have not viewed them to determine how easy they are to see. This comet has brightened up quite a bit over the last few weeks, and has even zipped right through the Big Dipper stars, then gone on through a fairly star poor region of sky. That said, the magnitude information I have found ranges all over the map, from That's a pretty significant difference - a large enough one, in fact, that if I were to suggest it could be seen in a "XYZ" sized scope, it may not be due to it's actual brightness overall.

    It may be close to Well, it's about to re-enter an area with well-known stars, but as you may have guessed from some of my other blog posts: It's cloudy here! So, rather than make a video and hope that everyone can see it, I'm making this blog post instead so you can find some information to search for it if your skies are clear.

    It will be conveniently situated near some bright stars in Auriga this coming week, so it's a great time to get out there and have a look, if you have the opportunity based on your local weather. The best map I've found for finding it this week is at AstroBob's site.

    He lists the magnitude quite high - around that 8. If it is there, it should be a great site in most any small telescope. If it's dimmer, it will be more of a fuzzball, and harder to see in binoculars. Either way, give it a shot, especially on the nights of the 1st through the 4th. Google can now appeal, but in doing so will need to argue against a variety of defenses, including the reasons specified by the ITC.

    According to Bloomberg, Google is disappointed about the decision and is considering its next step. This blog includes what to see in the night and daytime skies, thoughts on telescopes, binoculars, and other astronomy observing accessories and equipment, plus my own occasional notes on objects I've seen and observed. Oh, and the random theater or other "my take on life" post. In other words, there is always something interesting.

I spent a few hours last night checking out the comet and taking some photos. The comet is moving fast against the stars which makes imaging it a bit of a challenge.

    The trick is to filter out all of the star trails and just stack the comet, and then combine that with an RGB picture of the star field.

    Without the extra processing to remove the trailing stars, the image looks like this. This comet can be seen with a low powered telescope, binoculars, or even a DSLR camera.

Welcome to the Comet Report which is a monthly or seasonal article on the observations of comets by the amateur astronomy community and comet hunters from around the world!

    This comet is now being reported at visual magnitudes as high as 5. Download the report for further details! It is in Draco where the comet approached the passage of perigee time of closest distance to Earthmaximum visual brightness, and passage of perihelion time of closet distance to the Sun in a two — week period 31 March — 14 April.

    To get continuous catchup on the major comets for click on the following links from skylive! I am releasing a Powerpoint and pdf version of the report, but there is a wonderful animated gif using the JPL Solar System small body browser of the two comets approaching and departing Earth over the time period of 1 March to 1 April. This animated gif does not exist in the pdf version only a snapshot! I hope everyone enjoys it and I have a backlog of and reports that I plan to publish as good reference reports to study in learning more about comets and comet sciences!

    It has been a long time since the last Professor Comet Report, but there is a new one on what is available to see in the Late Summer skies of and what is coming for the rest of this year! There will be more information to come with a more thorough comet report hopefully in the next 1 - 2 weeks!

    Read over and enjoy! The tail has a fan shape with one end being the dust tail and other the ion tail that is very narrow, but stretches over a length of the sky great than the width of a perigee Moon.

    It is currently moving parallel with the 'crooked arm' of the Big Dipper heading in a westward direction while residing in the northern region of Canes Venatici until early - mid May! Currently the comet can be found on the meridian between pm and midnight CDT.

    Right now the comet originally predicted to be around mid-9th magnitude with observations placing it between 9 to 9. However, myself and two other astronomers at the George Observatory last Saturday night observed in both a 10" and 18" newtonian telescopes and it appears much brighter against the Houston light dome.

    I would say it is currently at 7th magnitude, but its original light curve would not place it at a maximum brightness of Magnitude 6. However, it could fade out if this is just an outburst even though it is a couple of months away from reaching perihelion. There peak brightness will occur during the month of July for comet Jacques and will continue to be brighter than 6th magnitude through at least September when it is between Hydra and Monoceros moving SW until it is lost to observers in the northern hemisphere by the first week of November.

    Comet Oukaimeden will peak at 5th magnitude during the month of September while speeding across the constellations of the Spring Sky very quickly from the central region of Monoceros at the beginning of that month heading eastward towards the eastern tail end of Hydra to the far ESE of Corvus before month's end.

    All three of these comets will be morning objects at there peak brightness in the few hours before the end of nautical twilight! It will still be visible for all of this month, but it will be about After that it will be more difficult to observe it as it moves further towards to the setting sun and by July 1 to see in night time skies look towards due west as the Sickle of Leo is beginning to set by 9 pm the comet will have an altitude of 20deg 21min above the horizon to the WNW.

    It will be visible again around 6 am in early September low in the sky due E and just east of the head of Hydra!

    Another possible comet I am now watching over in the forecasts for visibility is there is a small possibility of this comet reaching 5th magnitude in November of this year while it is moving eastward towards Leo and undergoing retrograde motion at the back end of the constellation through May !

    Also check out a new meteor shower predicted the weekend around the start of TSP It is spewing out a tail of debris that will move upwards towards the northern ecliptic hemisphere and the Earth will pass through this debris trail at it's eastern end.

    In the Transient Sky – December 2012

    The material will likely come from the comet's anti - tail with meteoroids reaching sizes above 1 mm. It could produce a heavy meteor shower with a ZHR predicted between - Meaning lots of meteors, but the radiant which is the point at which all meteors diverge from signifying the direction of the comet's path will lie in the constellation of Camelopardalis at a declination of 79 degrees making this a circumpolar meteor shower!

    Based on the data collected so far the prediction is that there will be no build up to this meteor shower it will occur the morning of 24 May starting from am CST through sunrise. After that nothing else! This is expected to be a one night, once in a lifetime major meteor shower, hopefully!

    Photometry result computed with FoCAs, which processes images based upon the. LOG file of Astrometrica, by means of Multibox method:. I attempted to yield the magnitude of the comet enclosed by infinite box, however, only finding an excessively unreliable result of around 5 mag, which may well be attributed to severe contamination of the tail.

    As I could not broach any good method to eliminate the signal from the tail, I simply gave up the fitting. I also attempted to do some simple morphological analysis of the comet, by running the IDL routines written by myself, whereby we can learn that activity around P. Judging from images taken by other observer a day ahead when the earth passes across the orbital plane of the comet, a tail used to appear in this position angle yet quickly vanished as the geometrical conditions changes.

    The image was stacked in median algorithm. The majority of frames were influenced by clouds more or less.

    As one may be aware of the plot of the lightcurve, it seems that the intrinsic variation has been presented. However, since I have not yet seen reports from other observers, it may reflect sky background variation between the spell when the comet was photographed. It would be a very interesting phenomenon to be verified. Nevertheless I will keep on the monitoring work of this comet, weather permitting. Feel free to e-mail me with any doubts or questions.

    It spends most of the month against the stars of eastern Sagittarius before approaching Capricornus at the end of the month. The Moon passes near Mars on the evening of the 14th. Jupiter — Jupiter reaches opposition on December 2nd. At that time it is at its brightest magnitude It spends the month slowly retrograding just north of the stars of the Hyades cluster in Taurus. At the start of the month it rises in the northeast at sundown. By the end of the month, it is well up in the eastern sky by nightfall.

    On Christmas night, the Moon and Jupiter will make a beautiful pair. Saturn — Saturn is an early morning object rising around am at the start of the month.

    By the end of the month, Saturn rises 2 hours earlier. The Moon passes close to Saturn on the mornings of the 10th. Venus — Venus rises around am on the 1st and am on the 31st. At magnitude The Moon passes to the south of Venus on the morning of the 11th. Venus will become more and more difficult to observe over the coming months as it approaches conjunction with the Sun. Mercury — Mercury is the last of the morning planets to rise.

    On the 1st it is magnitude It is still observable peaking above the southeast horizon just before day break through the middle of the month. The year is usually split in 2 with January through June having low rates with few major showers while July through December have high rates with many major showers. Meteor activity is still near an annual maximum this month.

    Sporadic meteors are not part of any known meteor shower. They represent the background flux of meteors. Except for the few days per year when a major shower is active, most meteors that are observed are Sporadics.

    This is especially true for meteors observed during the evening. During December mornings, 10 or so Sporadic meteors can be observed per hour from a dark moonless sky. From a dark, moon-less sky, the Geminids have been known to consistently produce rates of over meteors per hour at their peak.

    Unlike most showers that can only be observed in the early hours of the morning, the Geminids can be seen in good numbers as early as 10 pm and are great anytime after midnight. The Geminids will appear to radiate from the constellation of Gemini near the bright star Castor. According to analysis of meteor video data by Sirko Molau, the Geminids are active for almost an entire month between the dates of November 23 and December Though high rates are only possible within a few days of the peak.

    Most meteor showers are produced by comets with orbits that extend out to the orbit of Jupiter or beyond. The Geminids are different.
