SS: NASA announced comet Catalina a few days ago.. today.. as the sungrazer comet rounds the sun near Regulus, seems like a good day for me to post skymaps for this comet. today 25 august 2015 it is near Circinus on the path to the Mayan Hunab Ku.. next month from about the 8 – 16 September 2015 the comet Catalina wil pass between the stars Zeta Lup1 and Alpha Lupi of the Lupus the Wolf that is being pierced by the Spear of Centaurus. and on the 24th of September 2014 comet Catalina will pass between Kappa Centaurus and Eta Centaurus which is the Spear of Centaurus

SS: it has been suggested that the comet Catalina may brighten and if it brightens may put on a show during the christmas holidays.. the real show will be when it passes nearly over the star Arcturus on new years 2016! the crescent moon will just arrive at this time so we will have to see if any good images are produced.

How to Catch a Glimpse of a New Year’s Comet On New Year’s Day morning, Jan. 1, the comet will pass a mere 0.5 degrees – about the width of the moon – to the west of Arcturus. So if you head outdoors 60-90 minutes before dawn, let Arcturus serve as your guidepost (one ‘moon-width’ away) to find the faint, fuzzy patch of Comet Catalina. Of course, for optimal viewing, it’s recommended that you observe away from streetlights and city skyglow.  

If you miss Comet Catalina, don’t despair. You can still be treated to an alternate planetary extravaganza in the morning sky where Venus gleams in the southeast. Just before dawn on New Year’s Day, Saturn will be about 8 degrees to the lower left of Venus; by Jan. 4 the pair will appear even closer together. On Jan. 6 and 7, the waning crescent moon slips by the planetary pair. And on the morning of Jan. 8, Venus and Saturn are separated by a mere 0.4 degrees (less than one moon-width).

The celestial dance continues through January so that near month’s end, the five planets known as the ‘ancients’ span the sky from the southeast to the southwest in the morning twilight. In order (across the southern sky) these are Mercury, Venus, Saturn, Mars and Jupiter.

Comet Catalina Emerges Explanation: Comet Catalina is ready for its close-up. The giant snowball from the outer Solar System, known formally as C/2013 US10 (Catalina), rounded the Sun last month and is now headed for its closest approach to Earth in January. With the glow of the Moon now also out of the way, morning observers in Earth’s northern hemisphere are getting their best ever view of the new comet. And Comet Catalina is not disappointing. Although not as bright as early predictions, the comet is sporting both dust (lower left) and ion (upper right) tails, making it an impressive object for binoculars and long-exposure cameras. The featured image was taken last week from the Canary Islands, off the northwest coast of Africa. Sky enthusiasts around the world will surely be tracking the comet over the next few months to see how it evolves.

Comet Meets Moon and Morning Star Explanation: A crescent Moon and brilliant Venus met in predawn skies on December 7, a beautiful conjunction of planet Earth’s two brightest celestial beacons after the Sun. Harder to see but also on the scene was Comet Catalina (C/2013 US10). The fainter comet clearly sporting two tails, lunar night side, bright sunlit lunar crescent, and brilliant morning star, are all recorded here by combining short and long exposures of the same field of view. Pointing down and right, Catalina’s dust tail tends to trail behind the comet’s orbit. Its ion tail, angled toward the top left of the frame, is blowing away from the Sun. Discovered in 2013, the new visitor from the Oort cloud was closest to the Sun on November 15 and is now outbound, headed for its closest approach to Earth in mid-January.

Explanation: Will Comet Catalina become visible to the unaided eye? Given the unpredictability of comets, no one can say for sure, but it seems like a good bet. The comet was discovered in 2013 by observations of the Catalina Sky Survey. Since then, Comet C/2013 US10 (Catalina) has steadily brightened and is currently brighter than 8th magnitude, making it visible with binoculars and long-duration camera images. As the comet further approaches the inner Solar System it will surely continue to intensify, possibly becoming a naked eye object sometime in October and peaking sometime in late November. The comet will reside primarily in the skies of the southern hemisphere until mid-December, at which time its highly inclined orbit will bring it quickly into northern skies. Featured above, Comet Catalina was imaged last week sporting a green coma and two growing tails.

Lupus (constellation) In ancient times, the constellation was considered an asterism within Centaurus, and was considered to have been an arbitrary animal, killed, or about to be killed, on behalf of, or for, Centaurus.

Centaurus The Greeks depicted the constellation as a centaur and gave it its current name. It was mentioned by Eudoxus in the 4th century BCE and Aratus in the 3rd century BCE. In the 2nd century AD, Claudius Ptolemy catalogued 37 stars in Centaurus. Large as it is now, in earlier times it was even larger, as the constellation Lupus was treated as an asterism within Centaurus, portrayed in illustrations as an unspecified animal either in the centaur’s grasp or impaled on its spear.[11] The Southern Cross, which is now regarded as a separate constellation, was treated by the ancients as a mere asterism formed of the stars composing the centaur’s legs. Additionally, what is now the minor constellation Circinus was treated as undefined stars under the centaur’s front hooves.

Arcturus The name of the star derives from Ancient Greek Αρκτοῦρος (Arktouros) and means “Guardian of the Bear”,[29] ultimately from ἄρκτος (arktos), “bear”[30] + οὖρος (ouros), “watcher, guardian”.[31] It has been known by this name since at least the time of Hesiod.[7] This is a reference to its being the brightest star in the constellation Boötes (of which it forms the left foot), which is next to the Greater and Lesser Bears, Ursa Major and Ursa Minor.
