How many of these stars might you think have been found? Anyone ever see a star that has planets around it? (our own Sun, some may know of other stars) We can’t see the planets around other stars, but we can see the star. -
Catching up with Barnard's Star. Dave Eagle Within the Constellation Of
Catching Up with Barnard’s Star. Dave Eagle Within the constellation of Ophiuchus lies Barnard’s Star. It is a fairly faint red dwarf star of magnitude 9.53, six light years from Earth, so is fairly close to us. Its luminosity is 1/2,500th that of the Sun and 16% its mass. The diameter is estimated at about 140,000 miles, so it’s quite a small, faint star and well below naked eye visibility. So why is this star so well known? In 1916 Edward Barnard looked at a photographic plate of the area. When he compared this to a similar plate made in 1894, he noticed that one of the stars had moved between the time of the two plates being taken. Although all the stars in the sky in reality are all moving quite fast, from our remote vantage point on Earth most stars appear to appear virtually static during our lifetime as their apparent motion is extremely small. Barnard’s star, being so close and moving so fast, is one of the stars that bucks this trend. So fast indeed that it will subtend the apparent diameter equivalent to the Moon or Sun in about 176 years. So compared to other stars it is really shifting. The star is travelling at 103 miles per second and is approaching us at about 87 miles per second. In about 8,000 years it will become the closest star to us, at just under 4 light years and will have brightened to magnitude 8.6. Peter van de Camp caused great excitement in the 1960’s when he claimed to have discovered a planet (or more) around the star, due to wobbles superimposed on its movement. -

Snake River Skies The Newsletter of the Magic Valley Astronomical Society www.mvastro.org Membership Meeting President’s Message Saturday, August 13th 2016 7:00pm at the Herrett Center for Arts & Science College of Southern Idaho. Public Star Party Follows at the Colleagues, Centennial Observatory Club Officers It's that time of year: The City of Rocks Star Party. Set for Friday, Aug. 5th, and Saturday, Aug. 6th, the event is the gem of the MVAS year. As we've done every Robert Mayer, President year, we will hold solar viewing at the Smoky Mountain Campground, followed by a [email protected] potluck there at the campground. Again, MVAS will provide the main course and 208-312-1203 beverages. Paul McClain, Vice President After the potluck, the party moves over to the corral by the bunkhouse over at [email protected] Castle Rocks, with deep sky viewing beginning sometime after 9 p.m. This is a chance to dig into some of the darkest skies in the west. Gary Leavitt, Secretary [email protected] Some members have already reserved campsites, but for those who are thinking of 208-731-7476 dropping by at the last minute, we have room for you at the bunkhouse, and would love to have to come by. Jim Tubbs, Treasurer / ALCOR [email protected] The following Saturday will be the regular MVAS meeting. Please check E-mail or 208-404-2999 Facebook for updates on our guest speaker that day.

Pointers Is Dubhe Dubhe yellowish compared to Merak? 1 Merak THE PLOUGH Figure 1: Sketch of the northern sky in autumn. © Rob Peeling, CaDAS, 2007 version 1.2 Wynyard Planetarium & Observatory PUBLIC OBSERVING – Autumn North 1. On leaving the planetarium, turn around and look northwards over the roof of the building. Close to the horizon is a group of stars like the outline of a saucepan with the handle stretching to your left. This is the Plough (also called the Big Dipper) and is part of the constellation Ursa Major, the Great Bear. The two right-hand stars are called the Pointers. Can you tell that the higher of the two, Dubhe is slightly yellowish compared to the lower, Merak? 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 upwards 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 left 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. -

NASA Night Sky Network Ten years later Rosetta has now arrived at Comet 67P/Churyumov- Gerasimenko and just successfully made orbit today, 2014 August 6! Unfortunately, global events have foreshadowed this memorable event and news media have largely ignored this impressive space mission. AAC Member photo: The Rosetta comet mission may be the beginning of a story that will tell more about us -- both about our origins and evolution. (Hence, its name "rosetta" for the black basalt stone with inscriptions giving the first clues to deciphering Egyptian hieroglyphics.) Pictures received over past weeks are remarkable with the latest in the past 24 hours showing awesome and incredible detail including views that show the comet is a connected binary object rotating as a unit in 12 hours.

Double Star Measurements at the Southern Sky with a 50 Cm Reflector in 2016
Vol. 13 No. 4 October 1, 2017 Journal of Double Star Observations Page 495 Double Star Measurements at the Southern Sky with a 50 cm Reflector in 2016 Rainer Anton Altenholz/Kiel, Germany e-mail: rainer.anton”at”ki.comcity.de Abstract: A 50 cm Ritchey-Chrétien reflector was used for recordings of double stars with a CCD webcam, and measurements of 95 pairs were mostly obtained from “lucky images”, and in some cases by speckle interferometry. The image scale was calibrated with reference systems from the recently published Gaia catalogue of precise position data. For several pairs, deviations from currently assumed orbits were found. Some images of noteworthy systems are also pre- sented. “Chameleon” (PointGrey) with exposure times ranging Introduction from less than a millisecond to several tens of msec, Recordings of double star images were mostly eval- depending on the star brightness, on the filter being uated with “lucky imaging”: Seeing effects are effec- used, and on the seeing. Recordings were usually made tively reduced by using short exposure times, and selec- with a red or near infrared filter, in order to reduce ef- tion of only the best images for stacking, which results fects from chromatic aberrations of the Barlow lens, as in virtually diffraction limited images. In addition, well as from the seeing. Only the best frames, typically speckle interferometry was applied in some cases, as several tens and up to more than 100, were selected, large numbers of speckle images were found in several registered, and stacked. The pixel size of 3.75 µm recordings, caused by rather variable seeing conditions square results in a nominal resolution of 0.096 arcsec/ during this observing campaign. -
