Winter Observing Notes

On leaving the planetarium, turn around and look northwards over the roof of the building. To your right is a group of stars like the outline of a saucepan standing up on it’s handle. This is the Plough (also called the Big Dipper) and is part of the constellation Ursa Major, the Great Bear. The top two stars are called the Pointers. Check with binoculars. Not all stars are white. The colour shows that Dubhe is cooler than Merak in the same way that red-hot is cooler than white-hot. 2. Use the Pointers to guide you to the left, to the next bright star. This is Polaris, the Pole (or North) Star. Note that it is not the brightest star in the sky, a common misconception. Below and to the right are two prominent but fainter stars. These are Kochab and Pherkad, the Guardians of the Pole. Look carefully and you will notice that Kochab is slightly orange when compared to Polaris. Check with binoculars. © Rob Peeling, CaDAS, 2007 version 2.0 Wynyard Planetarium & Observatory PUBLIC OBSERVING – Winter Polaris, Kochab and Pherkad mark the constellation Ursa Minor, the Little Bear. -

For the last several thousand years, mankind has been a little bull-headed when it comes to Taurus. It has the distinction of being one of the oldest recognized constellations in the night sky. According to some records, it's been in this form for 4000 years or longer. In ancient times, the appearance of the sun in the celestial bull - a plow animal - marked the vernal equinox, and the beginning of spring planting. Our constellation for the month is located on the edge of the winter Milky Way, and our targets include; three open clusters, one of the brightest supernova remnants in the night sky and a lesser known planetary nebula. -

2011 Peeling the Onion & Binocular Asterisms
The Eldorado Star Party 2011 Binocular and Telescope Observing Clubs by Blackie Bolduc San Antonio Astronomical Association Purpose and Rules Welcome to the Annual ESP Binocular and Telescope Clubs! Their purpose is to give you the opportunity to observe some Fall showcase objects under the pristine Southwest Texas skies, thus displaying them to their best advantage. Binocular Club. In response to many requests for “something different”, you are offered the opportunity to chase down some lovely asterisms. There is a listing of twenty-five objects, all observable with binoculars of modest dimension. While the location center of mass of each object is specified, some imagination on your part will be required in order to “see” the figure suggested. Most will pop out easily, but others may be elusive. If you get stumped, you can always consult the “cheat sheets” posted in the registration/warming tent on the observing field. You need only observe any 15, your choice. Telescope Club. Since most of the readily accessible objects have already been included in one or more of the annual listings since this Party got underway in 2004, it is time to try to spice up our challenges. This year we offer “Peeling the Onion”: beginning with a relatively easy to identify major object, then turning to a sub-object just a bit harder, and on to another sub-sub-object ... peeling them off one at a time. There are five major groups, with on “onion” at the head of each, and six to eleven “peels” in close order behind. Of a total of forty objects, you need only “find” 25, your choice. -

Tim writes: This famous triplet of galaxies is known as ‘The Leo Trio,’ a catchy name for a wildly unlikely group of three large galaxies: M65, M66, and NGC 3628. All three are interacting with each other, and are quite close to each other, at least as far as large galaxies go. M65 and 66 are about 160,000 light years apart, about the same as the distance between us and the Magellanic Clouds. Imagine the view of each other these two galaxies enjoy! NGC 3628 is a bit farther from the two, about 300,000 years. If we think our view of M31 is unbelievable, suitably positioned astronomers in these galaxies enjoy a vastly superior view of their neighbors! M66 has been deeply disrupted by the interactions with its two neighbors. -
Reddening-Free Q Indices to Identify Be Star Candidates

De Bs. As. (CIC-PBA) Abstract. Astronomical databases currently provide high-volume spec- troscopic and photometric data. While spectroscopic data is better suited to the analysis of many astronomical objects, photometric data is rela- tively easier to obtain due to shorter telescope usage time. Therefore, there is a growing need to use photometric information to automatically identify objects for further detailed studies, specially Hα emission line stars such as Be stars. Photometric color-color diagrams (CCDs) are commonly used to identify this kind of objects. However, their identifi- cation in CCDs is further complicated by the reddening effect caused by both the circumstellar and interstellar gas. This effect prevents the gen- eralization of candidate identification systems. Therefore, in this work we evaluate the use of neural networks to identify Be star candidates from a set of OB-type stars. The networks are trained using a labeled subset of the VPHAS+ and 2MASS databases, with filters u; g; r; Hα; i; J; H, and K. -
WIDC-A-Ras Directory of Astronomical Data Files
Tin Mo. '« i WIDC-A-RaS 78-05 National Space Science Data Center/ World Data Center A For Rockets and Satellites Directory of Astronomical Data Files September 1978 PREFACE This Directory of Astronomical Data Files has been prepared by the Data Task Force of the Interagency Coordination Committee for Astronomy (ICCA) in cooperation with the National Space Science Data Center (NSSDC). The purpose of the Directory is to provide a listing.which will enable a user to locate stellar and extragalactic data sources keyed along with sufficient descriptive information to permit him to assess the value of the files for his use as well as the status and availability of the com- pilations. An ad hoc committee of the Federal Council for Science and Technol- ogy, ICCA, was composed of representatives from each of the major Federal agencies funding astronomical research. Its charge to the Data Task Force was "to outline a sequence of steps that the Federal agencies might take to coordinate the archiving of astronomical data in order to maximize utility." Among the recommendations contained in its final report, the Task Force advocated that the Federal, agencies "prepare a directory of astronomical data centers and other sources for both machine-readable and non-machine-readable data, including type of data, description of file, method of access, person-in-charge, and location for distribution to agen- cies and the astronomical researchers they support." The ICCA subsequent- ly reappointed the Task Force with a revised charge to suggest appropriate steps to carry out its recommendations, including cost estimates and ac- ceptability to the astronomical community. -

November has always been challenged to give a special performance for residents of the northern latitudes. The temperature after sundown is a bit chilly and most of us have already searched the closets for our Winter clothes. Well, the November of 2013 will not disappoint. The very bright object in the southwest at sundown is the magnificent planet Venus. A combination of special circumstances allows Venus to reach a brightness of –4.6 magnitude. Venus has very thick clouds that are highly reflective of the sunlight. It has an average distance of The Helix Nebula (NGC 7293) by ACA Member Len Marek. Meade 14” 0.723 AU’s from the Sun.
