The weather sure hasn’t been cooperative for observing, though! First I have a pretty cool announcement. Thanks to the efforts of club member Walt Cooney, there are 5 newly named asteroids in the sky.

Multiple Star Systems Observed with Corot and Kepler
Multiple star systems observed with CoRoT and Kepler John Southworth Astrophysics Group, Keele University, Staffordshire, ST5 5BG, UK Abstract. The CoRoT and Kepler satellites were the first space platforms designed to perform high-precision photometry for a large number of stars. Multiple systems dis- play a wide variety of photometric variability, making them natural benefactors of these missions. I review the work arising from CoRoT and Kepler observations of multiple sys- tems, with particular emphasis on eclipsing binaries containing giant stars, pulsators, triple eclipses and/or low-mass stars. Many more results remain untapped in the data archives of these missions, and the future holds the promise of K2, TESS and PLATO. 1 Introduction The CoRoT and Kepler satellites represent the first generation of astronomical space missions capable of large-scale photometric surveys. The large quantity – and exquisite quality – of the data they pro- vided is in the process of revolutionising stellar and planetary astrophysics. In this review I highlight the immense variety of the scientific results from these concurrent missions, as well as the context provided by their precursors and implications for their successors. CoRoT was led by CNES and ESA, launched on 2006/12/27,and retired in June 2013 after an irre- trievable computer failure in November 2012. It performed 24 observing runs, each lasting between 21 and 152days, with a field of viewof 2×1.3◦ ×1.3◦, obtaining light curves of 163000 stars [42]. Kepler was a NASA mission, launched on 2009/03/07and suffering a critical pointing failure on 2013/05/11. It observed the same 105deg2 sky area for its full mission duration, obtaining high-precision light curves of approximately 191000 stars. -

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.

Received: 30 June 2020; Accepted: 24 August 2020; Published: 28 August 2020 Abstract: Gamma-ray emission from the bright radio source 3C 84, associated with the Perseus cluster, is ascribed to the radio galaxy NGC 1275 residing at the centre of the cluster. Study of the correlated X-ray/gamma-ray emission from this active galaxy, and investigation of the possible disk-jet connection, are hampered because the X-ray emission, particularly in the soft X-ray band (2–10 keV), is overwhelmed by the cluster emission. -
Sunday October 19, 2014
Sunday October 19, 2014 Decided to use the Little Thompson Observatory’s telescopes tonight. I couldn’t connect to the 24”. Had connection failure issues. So I used the 18” f/14.2 and the 6” f/6 telescopes tonight. The 40mm eyepiece in 18” is 162x. The 22mm eyepiece in 6” is 41.5x. 7:00 PM. 68 degrees. Sky is clear. Wind is calm. Getting dark. Seeing and transparency Good. NGC 6929 7:27 PM 162x – Under a dim field star is this lopsided, faint, tiny oval glow. Glow goes to 2 o’clock from this star a tiny bit. Glow uniformly lit. NGC 6852 7:32 PM 162x – A brighter white star with very faint circular halo glow around it. With O3 see the halo a bit better and brighter. Star still prominent. NGC 6843 7:35 PM 162x – 7 very dim stars form this asterism in a small, rough circular pattern. NGC 6858 7:37 PM 162x – An asterism of 9 very dim stars in a diamond shape. NGC 6773 7:39 PM 162x – 5 stars form a box of 3 magnitudes with brightest still dim. PK 38-25.1 7:45 PM 162x – A stellar PN. A brighter white star. With O3, see a tiny bit of halo around it. It is small and hard to see. Looks like an out of focus star. Pal 11 7:49 PM 162x – With AV and waiting, see 3-4 very faint stars once in a while. In between a nice asterism pattern where picture shows it should be and where these 3-4 stars pop in. -

A Basic Requirement for Studying the Heavens Is Determining Where In
Abasic requirement for studying the heavens is determining where in the sky things are. To specify sky positions, astronomers have developed several coordinate systems. Each uses a coordinate grid projected on to the celestial sphere, in analogy to the geographic coordinate system used on the surface of the Earth. The coordinate systems differ only in their choice of the fundamental plane, which divides the sky into two equal hemispheres along a great circle (the fundamental plane of the geographic system is the Earth's equator) . Each coordinate system is named for its choice of fundamental plane. The equatorial coordinate system is probably the most widely used celestial coordinate system. It is also the one most closely related to the geographic coordinate system, because they use the same fun damental plane and the same poles. The projection of the Earth's equator onto the celestial sphere is called the celestial equator. Similarly, projecting the geographic poles on to the celest ial sphere defines the north and south celestial poles. However, there is an important difference between the equatorial and geographic coordinate systems: the geographic system is fixed to the Earth; it rotates as the Earth does . The equatorial system is fixed to the stars, so it appears to rotate across the sky with the stars, but of course it's really the Earth rotating under the fixed sky. The latitudinal (latitude-like) angle of the equatorial system is called declination (Dec for short) . It measures the angle of an object above or below the celestial equator. The longitud inal angle is called the right ascension (RA for short). -
