Primary system name. Gamma Leonis. Alternative system names. N/A. Gamma-2 Leonis. Alternative star names. gamma 1 Leo, gam01 Leo, γ1 Leo, γ1 Leonis, γ Leo A, Gamma Leonis A, gamma Leo A, gam Leo A, Algieba A, Al Gieba A, HD 89484, HIP 50583 A, TYC 1423-1349-1, SAO 81298, BD+20 2467 A, WDS J10200+1950 A, STF 1424 A. Gamma Leonis's wiki: Gamma Leonis (γ Leo, γ Leonis) is a binary star system in the constellation Leo. It has the traditional name Algieba or Al Gieba . Name origin and history The name Algieba originates from the Arabic الجبهة Al-Jabhah Gamma Leonis b is an extrasolar planet located 125.5 light years away in the constellation Leo, orbiting the giant star Gamma Leonis. On November 6, 2009, a planetary companion around primary star Gamma1 Leonis has been announced. Moreover radial velocity variations would also hint two strong signals at 8.5 and 1340 days. The former periodicity is likely due to stellar pulsation, whereas the latter could be indicative of the presence of an additional planetary companion with 2.14 Jupiter masses Gamma Leonis (γ Leo / γ Leonis) is a binary star system in the constellation Leo. It also has the traditional name Algieba or Al Gieba. Name origin and history. The name "Algieba" originates from the Arabic "Al-Jabhah", meaning "the forehead". -

Snake River Skies The Newsletter of the Magic Valley Astronomical Society www.mvastro.org Membership Meeting President’s Message Tim Frazier Saturday, April 14th 2018 April 2018 7:00pm at the Herrett Center for Arts & Science College of Southern Idaho. It really is beginning to feel like spring. The weather is more moderate and there will be, hopefully, clearer skies. (I write this with some trepidation as I don’t want to jinx Public Star Party Follows at the it in a manner similar to buying new equipment will ensure at least two weeks of Centennial Observatory cloudy weather.) Along with the season comes some great spring viewing. Leo is high overhead in the early evening with its compliment of galaxies as is Coma Club Officers Berenices and Virgo with that dense cluster of extragalactic objects. Tim Frazier, President One of my first forays into the Coma-Virgo cluster was in the early 1960’s with my [email protected] new 4 ¼ inch f/10 reflector and my first star chart, the epoch 1960 version of Norton’s Star Atlas. I figured from the maps I couldn’t miss seeing something since Robert Mayer, Vice President there were so many so closely packed. That became the real problem as they all [email protected] appeared as fuzzy spots and the maps were not detailed enough to distinguish one galaxy from another. I still have that atlas as it was a precious Christmas gift from Gary Leavitt, Secretary my grandparents but now I use better maps, larger scopes and GOTO to make sure [email protected] it is M84 or M86. -
Double and Multiple Star Measurements in the Northern Sky with a 10” Newtonian and a Fast CCD Camera in 2006 Through 2009
Vol. 6 No. 3 July 1, 2010 Journal of Double Star Observations Page 180 Double and Multiple Star Measurements in the Northern Sky with a 10” Newtonian and a Fast CCD Camera in 2006 through 2009 Rainer Anton Altenholz/Kiel, Germany e-mail: rainer.anton”at”ki.comcity.de Abstract: Using a 10” Newtonian and a fast CCD camera, recordings of double and multiple stars were made at high frame rates with a notebook computer. From superpositions of “lucky images”, measurements of 139 systems were obtained and compared with literature data. B/w and color images of some noteworthy systems are also presented. mented double stars, as will be described in the next Introduction section. Generally, I used a red filter to cope with By using the technique of “lucky imaging”, seeing chromatic aberration of the Barlow lens, as well as to effects can strongly be reduced, and not only the reso- reduce the atmospheric spectrum. For systems with lution of a given telescope can be pushed to its limits, pronounced color contrast, I also made recordings but also the accuracy of position measurements can be with near-IR, green and blue filters in order to pro- better than this by about one order of magnitude.

Gov Aker Telescope Operators Manual
Gov Aker Telescope Operators Manual Revised September 3, 2014 Craig Nance Director Mount Graham International Observatory Steward Observatory University of Arizona [email protected] Page 1 of 97 Governor Hunt Aker Governor Hunt Aker was born on Dec 24, 1917. “Gov Aker” served in the Army Air Corps during World War II. After the war he became an assistant football coach at Northern Arizona University and then was a teacher and coach at Safford High School during the 1950’s. He went on to become assistant superintendent of public instruction at the State capital in Phoenix. In 1964 he became the director of youth programs for the Secretary of the Interior. Later, starting in 1986 he served as the mayor of Safford and was a member of the Safford High School Scholarship and Educational Foundation. He passed away on June 30, 1993. His resting place is the Safford Cemetery. To those that knew him Gov Aker was known for his incredible dedication and commitment to Arizona, his sense of humor, his love of golf, and his love of the people he represented. Source: Various public records, including Congressional Record, 103rd Congress, Page S9053 Page 2 of 97 Introduction The Gov Aker telescope is a research-class telescope that is presently used primarily for public education. It is hoped that through this manual that the telescope enjoys a strong level of usage, as this is what benefits the telescope the most. Operators should not be hesitant to use the telescope, being mindful of a reasonable number of safety precautions that are highlighted in this manual. -

DOCUMENT RESUME ED 094 956 SE 016 611 AUTHOR Bolles, William H.; And Others TITLE Earth and Space Science. A Guide for Secondary Teachers. INSTITUTION Pennsylvania State Dept. of Education, Harrisburg. Bureau of Curriculum Services. PUB DATE 73 NOTE 200p. EDRS PRICE MF-$O.75 HC-$9.00 PLUS POSTAGE DESCRIPTORS Aerospace Education; *Astronomy; *Curriculum Guides; *Earth Science; Geology; Laboratory Experiments; Oceanology; Science Activities; Science Education; *Secondary School Science IDENTIFIERS Pennsylvania ABSTRACT Designed for use in Pennsylvania secondary school science classes, this guide is intended to provide fundamental information in each of the various disciplines of the earth sciences. Some of the material contained in the guide is intended as background material for teachers. Five units are presented: The Earth, The Oceans, The Space Environment, The Atmosphere, and The Exploration of Space. The course is organized so that students proceed from the familiar, everyday world to the atmosphere and the space environment. Teaching geology in the fall takes advantage of weather conditions which permit field study. The purpose of the Earth and Space Science course is to encourage student behaviors which will be indicative of a broad understanding of man1s physical environment of earth and space as well as an awareness of the consequences which could result from changes which man may effect.(PEB) BEST COPY AVAILABLE U S DEPARTMENT OF HEALTH.
