Vol. 45, No. 12 The OBSERVER of the Twin City Amateur Astronomers December 2020 PRESIDENT’S NOTE The OBSERVER When December arrives, I like to reflect on is the monthly electronic newsletter of Twin the year behind and plan for the year ahead. City Amateur Astronomers, Inc., a registered There’s certainly plenty to reflect on, but right 501(c)(3) non-profit educational organiz- now reflection seems more like rehashing. This ation of amateur astronomers interested in year, I’m concentrating on looking ahead. I’ll set studying astronomy and sharing their hobby with the public. some goals for next year (I don’t really believe in “New Year’s” resolutions), and some of those goals will be relative to my astronomical TCAA OFFICERS & CHAIRPERSONS aspirations. I’ve found that having goals President, Director, & Property Manager improves my chances of making progress. Tim Stone 309-531-2401 Last year I had the goal of beginning my [email protected] journey in radio astronomy, a goal I achieved Vice President & Director/Membership Coord. and am very much enjoying. I’ve recorded President Tim Stone Tom Willmitch 309-846-2423 radiation from cold atomic hydrogen in our own galaxy, a signal that is still being used to [email protected] refine our understanding of the structure of the Milky Way and our position in it. It’s Treasurer & Director/Registered Agent fascinating to see the signal rise and fall as the earth’s rotation sweeps my antenna across Dave Osenga 309-287-0789 the plane of the Milky Way and see how the signal from different spiral arms is blue or [email protected] red shifted by their velocity relative to ours. It feels great to have set this goal and Assistant Property Manager/ALCor achieved it. Scott Wade 309-310-2464 Next year my goals include some more radio astronomy results, including creating [email protected] my own map of this hydrogen signal for the entire sky visible from here. I also have 5th Director spectroscopic, deep sky astrophotographic, and visual observing goals. If you know me, Sunil Chebolu 678-896-5967 you know I’m somewhat easily distracted, so I’ve written these goals out, and I’ll review [email protected] them every now and then to keep myself on track. Secretary/Historian/Editor What are your goals for 2021? Perhaps you’ve thought about completing your first Carl J. Wenning 309-830-4085 Astronomical League observing program, or there’s another program you’d like to [email protected] undertake. Perhaps it’s to get that telescope out and look at the moon through all its Technology Coordinator/Assistant Editor phases. Perhaps you want to learn more about stars, observe satellites, count sunspots, Sandullah Epsicokhan 309-828-0227 or any one of a plethora of accomplishments you want to feel good about in December [email protected] of 2021. Take some time to think about your astronomy goals this month. Write them Webmaster down. Plan how to achieve those goals and get to it! It’s not hard, won’t take a lot of time, Lee Green 309-454-7349 and you’ll find holding yourself to those goals will increase your love and appreciation for [email protected] this fantastic hobby of ours. AL Observing Club Coordinator If you decide to set astronomy goals for 2021, why don’t you share them with us. Lisa Wentzel unlisted number Send us a “In 2021 I plan to…” email, and we’ll put them in The OBSERVER. You might [email protected] just find someone else with similar goals, and you can “team up” for an even better experience in meeting those goals in 2021. I’ll start. Here are mine: The OBSERVER Carl J. Wenning, Editor Spectrographic: Measure red/blue shift in stellar winds; observe stellar spectral features to magnitude 10; measure Jupiter rotational red/blue shift; explore cross- Submission deadline two days before the end of each month. correlation signal processing Radio: Observe HI radio emission; create an all-sky HI emission map MEMBERSHIP DUES Astrophotography: High resolution photography with the 0.6m – Heart Nebula, Soul Individual Adult/Family $40 Full-time Student/Senior $25 Nebula, Double Cluster mosaic (Senior status equals ages 60+) Visual: Complete all four NCRAL mini-Messier marathons; complete the Stellar Evolution observing program from the Astronomical League.

What's In This Issue? HRPO’s Great American Eclipse Event Summary (Page 2) President’s Message Secretary's Summary Outreach Report - FAE Light Pollution Committee Report Recent Forum Entries 20/20 Vision Campaign Messages from the HRPO Spooky Spectrum Observe The Moon Night Natural Sky Conference HRPO 20th Anniversary Observing Notes – Phoenix & Mythology Like this newsletter? See past issues back to 2009 at http://brastro.org/newsletters.html Newsletter of the Baton Rouge Astronomical Society October 2017 President’s Message The first Sidewalk Astronomy of the season was a success. We had a good time, and About 100 people (adult and children) attended. Ben Toman live streamed on the BRAS Facebook page. See his description in this newsletter. A copy of the proposed, revised By-Laws should be in your mail soon. Read through them, and any proposed changes need to be communicated to me before the November meeting. Wally Pursell (who wrote the original and changed by-laws) and I worked last year on getting the By-Laws updated to the current BRAS policies, and we hope the revised By-Laws will need no revisions for a long time. We need more Globe at Night observations – we are behind in the observations compared to last year at this time. We also need observations of variable stars to help in a school project by a new BRAS member, Shreya.

Stetson, Supervisor (Herzberg Institute of Astrophysics) Dr. Don A. VandenBerg, Supervisor (Department of Physics and Astronomy) Dr. Kim Venn, Departmental Member (Department of Physics and Astronomy) Dr. Jon Willis, Departmental Member (Department of Physics and Astronomy) ABSTRACT We have obtained broad-band NIR-photometry for six Galactic star clusters, M92, M15, M13, NGC1851, M71 and NGC6791, as observed with the WIRCam wide-field imager on the Canada-France-Hawaii Telescope; supplemented by images taken with HAWK-I on VLT. From the resultant (V − J)-V and (V − K)-V colour-magnitude diagrams, fiducial sequences spanning the range in metallicity, −2.4 ≤ [Fe/H] ≤ +0.3, have been defined which extend from the tip of the red-giant branch to ∼ 2.5 magnitudes below the main-sequence turnoff.

Mar. 13th, 2021 Field Tested Systems Time: 7:30 pm Where: Online (Zoom) See instructions for registering to participate in the meeting on Page 8. Speaker: Tom Field Table of Contents Preview of Mar. 2021 Talk 1 Recent Astronomy Highlights 2 Sighting by WISPR 2 Exploring the Sky 3 Sky Watchers 3 Perseverance Landing 3 Occultations 5 Calendar of Events 7 Image credit: Tom Field Abstract: Even if you wanted to touch a star, they’re all impossibly distant. Despite these great distances, astronomers have learned an enormous amount about stars. How? The most common method to study the stars is called spectroscopy, which is the science of analyzing the colorful rainbow spectrum produced by a prism-like device. Until recently, spectroscopy was too expensive and too complicated for all but a handful of amateurs. Today, though, new tools make spectroscopy accessible to almost all of us. You no longer need a PhD, dark skies, long Image Credit – NASA, JPL, University exposures, enormous aperture … or a big budget! With your current of Arizona telescope and FITS camera (or a simple web cam or even a DSLR Victoria Crater, near the equator of Mars, as imaged by the High without a telescope) you can now easily study the stars yourself. Wouldn’t Resolution Imaging Experiment you like to detect the atmosphere on Neptune or the red shift of a quasar (HiRISE) on the Mars right from your own backyard?! Reconnaissance Orbiter.

  • 2015 Clear Sky Nights by Art Rae
    2015 Clear Sky Nights by Art Rae Volume 41, No. 4 Windsor Centre - Here is my tally of clear night skies for 2015 from my location near River Canard, Ontario. This is an unofficial "look out the window" count of all the nights I saw what I considered a "clear sky". Seeing doesn't enter into it. But it gives an idea of what kind of observing year we had this past year. 2015 brought my total up to 93 clear nights, about 25% of the total nightly skies for the year. If you thought we didn't get a lot of clear skies you are probably right. In some recent years we've experi- enced as high as 120 clear nights others as low as 83. 2013 showed 119 open sky nights. Well maybe we will have a better chance in 2016. This year we get an ex- tra day to count.
