    OCTOBER 2 0 0 6 �������������� http://www.universetoday.com �������������� TAMMY PLOTNER WITH JEFF BARBOUR 283 SUNDAY, OCTOBER 1 In 1897, the world’s largest refractor (40”) debuted at the University of Chica- go’s Yerkes Observatory. Also today in 1958, NASA was established by an act of Congress. More? In 1962, the 300-foot radio telescope of the National Ra- dio Astronomy Observatory (NRAO) went live at Green Bank, West Virginia. It held place as the world’s second largest radio scope until it collapsed in 1988. Tonight let’s visit with an old lunar favorite. Easily seen in binoculars, the hexagonal walled plain of Albategnius ap- pears near the terminator about one-third the way north of the south limb. Look north of Albategnius for even larger and more ancient Hipparchus giving an almost “figure 8” view in binoculars. Between Hipparchus and Albategnius to the east are mid-sized craters Halley and Hind. Note the curious ALBATEGNIUS AND HIPPARCHUS ON THE relationship between impact crater Klein on Albategnius’ southwestern wall and TERMINATOR CREDIT: ROGER WARNER that of crater Horrocks on the northeastern wall of Hipparchus. Now let’s power up and “crater hop”... Just northwest of Hipparchus’ wall are the beginnings of the Sinus Medii area. Look for the deep imprint of Seeliger - named for a Dutch astronomer. Due north of Hipparchus is Rhaeticus, and here’s where things really get interesting. If the terminator has progressed far enough, you might spot tiny Blagg and Bruce to its west, the rough location of the Surveyor 4 and Surveyor 6 landing area.

  • MONTHLY OBSERVER's CHALLENGE Las Vegas
    MONTHLY OBSERVER’S CHALLENGE Las Vegas Astronomical Society Compiled by: Roger Ivester, Boiling Springs, North Carolina & Fred Rayworth, Las Vegas, Nevada With special assistance from: Rob Lambert, Las Vegas, Nevada SEPTEMBER 2016 Introduction The purpose of the Observer’s Challenge is to encourage the pursuit of visual observing. It’s open to everyone that’s interested, and if you’re able to contribute notes, and/or drawings, we’ll be happy to include them in our monthly summary. We also accept digital imaging. Visual astronomy depends on what’s seen through the eyepiece. Not only does it satisfy an innate curiosity, but it allows the visual observer to discover the beauty and the wonderment of the night sky. Before photography, all observations depended on what the astronomer saw in the eyepiece, and how they recorded their observations. This was done through notes and drawings, and that’s the tradition we’re stressing in the Observers Challenge. We’re not excluding those with an interest in astrophotography, either. Your images and notes are just as welcome. The hope is that you’ll read through these reports and become inspired to take more time at the eyepiece, study each object, and look for those subtle details that you might never have noticed before. NGC-7009 – The Saturn Nebula – Planetary Nebula In Aquarius The Saturn Nebula, which got its name from the distinctive shape as seen in some amateur instruments and images, is a planetary nebula in Aquarius. It’s also known by the more formal name of NGC-7009 and the even more obscure PK 37-34.1.

  • Central Coast Astronomy Virtual Star Party November 21St 7Pm Pacific
    Central Coast Astronomy Virtual Star Party November 21st 7pm Pacific Welcome to our Virtual Star Gazing session! We’ll be focusing on objects you can see with binoculars or a small telescope, so after our session, you can simply walk outside, look up, and understand what you’re looking at. CCAS President Aurora Lipper and astronomer Kent Wallace will bring you a virtual “tour of the night sky” where you can discover, learn, and ask questions as we go along! All you need is an internet connection. You can use an iPad, laptop, computer or cell phone. When 7pm on Saturday night rolls around, click the link on our website to join our class. CentralCoastAstronomy.org/stargaze Before our session starts: Step 1: Download your free map of the night sky: SkyMaps.com They have it available for Northern and Southern hemispheres. Step 2: Print out this document and use it to take notes during our time on Saturday. This document highlights the objects we will focus on in our session together. Celestial Objects: Moon: The moon is first quarter, which is really good for star gazing! Planets: Mars was at its closest approach to Earth just over a month ago and is still a great target for viewing and photographing with medium-size telescopes. Be patient and use tracking as you wait for the air to steady down. It’s worth the effort when you see the poles through an 8” scope!

To those whom I may fail to personally acknowledge here, I offer my apology, for there are uncountable numbers who have contributed either directly, or indirectly to this study.

I do. After a cliff-hanger experience in Germany - it can happen. Early on the morning of August 11th in Einsbach, Germany, our home away from home for the eclipse, the sun rose against a beautifully clear blue sky. It was like India in 1995 and Australia in February 1999. Not a cloud in the entire sky. After breakfast I made a call to Beth Yule, the tour agent for Amateur Astronomers Inc. (AAI) from New Jersey, for instructions as to where to join her group. I've known Beth and members of AAI since the eclipse expedition to the African Sahara Desert in 1973 and I was pleased that she invited us along, and also had a chance to meet eclipse chasing friends of old.

Capricornus (Sea Goat) Alpha 1 and Alpha 2 Capricorni: Located in the tail of the goat, this is a naked eye yellow double star (both are yellow), about 376” apart. Alpha 1 is a supergiant star about 500 light years away with a magnitude of 4.2 and Alpha 2 is a giant star about 109 light years away with a magnitude of 3.6 visual. Alpha 1 has a magnitude 9.2 companion about 45” away and Alpha 2 has a magnitude 11.0 companion about 6.6” away. Beta Capriconi: Located in the base of the tail of the goat is a white and blue double about 205” apart. The white component is magnitude 3.4 while the blue companion is magnitude 6.2 visual. This double is estimated to be 150 light years away. The white component is about 100 times brighter than our sun. This is a colorful double easily split by any telescope.
