Tamke-Allan Observatory invites people interested in astronomy to meet at 1930h on the first and 3rd Saturdays for celestial observing between 7:30 and 11 PM. Or sometimes later, depending on the sky.

JUNO arrived at Jupiter on July 4, 2016. Here's our exhibit at the American Museum of Science and Energy, Oak Ridge. Visit them!

Telescope making/mirror grinding is a hands-on activity for everyone (students, amateur astronomers and visitors).

 

Roy Morrow used James Nolan's camera to capture a beautiful image of the Dumbell Nebula (a planetary nebula from an exploded star). I took a photo of it with my cell phone and it looked like this:

The scope camera had a better image, but I took this one with my iPhone. One can see the remaining white dwarf star at the center of the Dumbell.

May 6 was a busy evening, as we entertained the students and parents at Linden School in Oak Ridge, at their new amphitheater. Saturn and Luna were excellent targets. What a nice group of people! We had 6 telescopes and several hundred observers.

In truth, there were 2 Saturns, but the first one had wheels and rolled away. The second had beautiful rings and a prominent moon, and delighted the crowd.

Recent (Nov. 2013) astrophotography by Shawn Harrison was displayed in real time on the TAO Mobile Solar Observatory rear-screen projector:


Along with decoding the "Enigma" poem by Galileo, we found this in the sky (telescope work at TAO on April 2 showing M1 through the 12" Meade by UJ and DR):

That's the photo of the Crab Nebula 6000 LY distant, at the start of history according to the young earth guys. That light has been traveling for 6000 years. How about the more distant objects? The light has been traveling a lot longer. The actual image is better since you're seeing a CCD image rendered on a monitor, covered by a filter, captured by a handheld iphone camera, resized, transmitted rendered in your monitor, etc.

We discussed whether Galileo could have seen the Crab Nebula in beautiful skies Italian without light pollution, about the year 1535. He saw and wrote extensively about Saturn. The answer is perhaps yes.

We looked at some astrophotos, including those by local people (e.g., as in the photo above, taken just before the hard drive filled up). Skies provided great visibility, but seeing near the horizon was bad because of the turbulence.

Bring telescopes, red flashlights, astronomy gadgets and cookies. The evening will offer opportunities for viewing and Luna (with craters), and Jupiter with 3-4 nearby moons.

Expect Stargazes on the first and third Saturday evenings of each month. Amateur astronomers bring telescopes and binoculars and offer views of astronomical objects, while visitors are invited to bring their telescopes, questions and cookies to share with the astronomers.

...............................................................

Here's a gazing ball image from 5/19. Note the heavy light pollution along the horizon and illumination of the classroom by the light trespass (click for full size image). This is a 11 PM photo and the light pollution prevents viewing around the horizon.


Tamke-Allan Observatory of Rockwood is a treasure of Roane County. It hosts free Public Stargazes on the first and third Saturday evenings of each month. These stargazes have opened the night skies, free of charge to everyone, for the past 10 years. Amateur astronomers bring telescopes and binoculars and offer views of astronomical objects, while visitors are invited to bring their questions and cameras and meet the astronomers. Kids are especially welcome.

Too much light causes glare – a hazard on our highways. Directing light downward where it is needed conserves energy and gives us a safer, more secure community. It also keeps our observatory open for education and research. When was the last time that you could see our beautiful milky way? We are losing our Roane County Heritage in the glare of unshielded lights.

Star Party Etiquette

* Bring a red flashlight and avoid using any white light after dark.
* Get to know the lighting controls for your vehicle and ensure as little white light as possible shines from your vehicle. If you cannot control the lights, choose to park as far away from the telescopes as practical.
* Carefully enter the observing location. Speeding into a parking area full of telescopes and observers is a recipe for an accident.

TAO Academic Associates are Colleges, Universities and other educational institutions that have both faculty and students that share research and scientific goals. The emphasis is not just scientific -- this is a humanistic endeavor that encourages both cultural exchange and critical thinking.

Our Associate Groups:

ORION

ORION is a local science and engineering oriented group that supports astronomy public events, field trips and lectures on current related topics. Group activities are centered in Oak Ridge and at TAO. Orion members support the Tamke Allan Observatory family nights on the first and second Saturday of each month. Monthly meetings are held at the Oak Ridge Historic Grove Theater on third Wednesday evenings at 1900 h (7:00 PM).

Astronomers from the Oak Ridge Isochronous Observation Network (ORION) and Knoxville Observers participate in these events.. TAO serves as the center for astronomy classes, optical astronomy and radio astronomy observing as well as and public stargazes on the first and third Saturdays of each month.

Celestial events of September, 2016


This September 3 and 17,, take yourself and your family on a journey to the stars, departing from Tamke-Allan Observatory.

The Northern Milky Way — Early in the month, around 9 PM, the "Summer Triangle" of three bright stars Vega, Deneb and Altair will be nearly overhead. In the northernmost portion of the Summer Triangle, you'll see a bright portion of the northern Milky Way. Point a [telescope] there and you'll discover that the fuzzy outlines of the Milky Way will resolve into vast fields of stars to explore.
Planetary Nebulas in the Summer Triangle — Use a star chart and see how many of these planetary nebulas you can find in September: the famous Ring Nebula (M57) in the constellation Lyra; the Dumbbell Nebula (M27) in Vulpecula; and the "Blinking Planetary," NGC 6826 in Cygnus. Not far outside the western boundary of the Summer Triangle is a small, but intensely colorful planetary nebula, NGC 6572. All these can be seen in a 6" or larger telescope. Enhance your views of these distant clouds of dust and gas with an Oxygen-III filter.


The Galaxy Next Door — In early September, lurking low in the northeast sky is another galaxy, separate from our Milky Way — the Great Andromeda Galaxy (M31). From a very dark area without a lot of light pollution, the core of M31 is visible with the unaided eye as a slightly fuzzy spot in the sky. A pair of 7x50, 9x63 or larger binoculars will give you a much better view and any telescope will help reveal some of the neighboring galaxy's subtle dust lanes.
Dip into the Whirlpool — If you haven't tracked down "The Whirlpool Galaxy," M51, just off the handle of the easily recognizable Big Dipper asterism, do it now while you still can! It will be too low for most to get a good view after September and you'll need to wait until late winter or next spring to catch a good view of this truly picturesque galaxy. An 8" or larger telescope will help you see faint details of M51 more clearly.


A Brilliant Open Star Cluster — Off the western end of the constellation Cassiopeia is the beautiful Open Star Cluster M52. You can find it with 50mm or larger binoculars from a dark sky site, but the view is definitely better in a telescope. With an 8" or larger scope, and with the aid of an Orion UltraBlock or Oxygen-III eyepiece filter, you may even be able to catch views of faint nebulosity surrounding M52.


Don't Miss the Double Cluster — If you enjoyed observing M52, you'll love the popular favorite "Double Cluster in Perseus." Lying between constellations Cassiopeia and Perseus is a bright, fuzzy spot in the Milky Way, and a binocular will reveal two, bright open star clusters close to one another. For a real treat, use a telescope equipped with a wide-angle eyepiece to explore these sparkling clusters. In early September the "Double Cluster" appears low in northeastern skies around 9 PM, but it becomes a real showpiece later in the evening as it climbs higher in the sky.


The Globular Star Clusters of September — Off the western side of the constellation Pegasus, three globular star clusters almost line up in a row from north to south. These globular clusters are, from north to south, M15 in Pegasus, M2 in Aquarius and M30 in Capricorn. From a dark sky site you can easily find all of them in 50mm or larger binoculars.


A Thinly Veiled Challenge — A challenging object to see in September is the supernova remnant called the Veil Nebula, located in the constellation Cygnus which is nearly overhead as soon as it gets dark. With the help of a star chart, aim your telescope at the naked eye star 52 Cygni. One branch of the Veil crosses over this star and to the east are brighter segments of this roughly circular nebula. While the Veil Nebula can be seen in big binoculars by expert observers under very dark skies, you will likely need at least a 5" aperture telescope and an Orion Oxygen-III eyepiece filter if you are anywhere near city lights.

Here's a photo of our STEM teacher's group, learning "From Earth to the Stars with STEM" on Dec. 8:

Dark skies on a night in December revealed Aurora from TAO (note our weather station). Photo by Astronomy class student Robert Quinn.

The following sunset photo was taken on Astronomy Day, May 7, 2006.


Sometimes our POD actually glows. The source of the light is something that visitors are encouraged to discover.

Solar Photos

Here are photos from Heather Fries showing the sunset, and some of our visitors.

We had a welcome to guests followed by a classroom presentation at 1930 h on the Siemans competition projectt in using computer models to steer particle beams. This work has several applications in astronomy and materials research. Our presenters were Oak Ridge High School students Scotty Chung Yajit Jain, and Carlos del-Castillo-Negrete, and. These students are the 2010-11 Siemens Foundation Regional Finalists in the prestigious Siemens Competition in Math, Science & Technology. They are among 94 finalists selected from 2,033 student researchers from 36 states and are competing for Siemens awards that range from $1000 to $100,000. We had a hot grill and live music from the astro-country folk band outside

Maryville Scouts visited us on March 5

Scoutmaster Chris brought Troop 700 from Maryville and they filled the classroom. What a group -- with questions and a lot of interest in learning how to find Jupiter (and moons) with our 8" refractor. They were already a part of the TAO action since it was one of their Eagle Scouts who built our camping area in our woods. They brought us coffee and 3 types of strudle (!) and we shared our telescopes (Thanks Jan, DR, and George), Jim Long's Spagetti, 2 kinds of bread, cookies, chips, etc. It was a beautiful evening, after those clouds cleared.

Eye patches for Dark Adaptation
I used to wear an eye patch to dark adapt but later, decided to simply close an eye when needed. I was wrong.

Itt turns out that pirates were on the right track in wearing eye patches. I had thought that they should just have closed their eyes to dark-adapt to go below-decks but no -- blood transmits wavelengths (heavy curve) that bleach ocular rhodopsin (light curve)

Shiver me timbers and belay any discard-patch advisories. Wearing an eye patch for dark adaptation is a good idea.

Jan. 17 TAOrem launch

This was a success. Past and future students and amateur astronomers were invited. Launch of this remote sensing balloon occurred at 4 PM on 1/17/2015 from Tamke-Allan Observatory in East TN, USA, 35.8325 Lat, -84.618 Lon. Transmissions were 110baud ASCII, 8b, 2s, np on 433.97462 MHz upper sideband, with ID WA4ADG-1 as announced on http://arhab.org/hab_launch_list.php and tracked on http://www.roanestate.edu/obs
and on Twitter @TAOrem.

Our 2 launches of 2014 used instrumented weather balloons (monitoring position, temp, ionizing radiation, solar insolation, etc.), and attained about 100,000 foot altitude before bursting as expected.. The Jan 17 launch was more experimental, using a 1/3 filled non-expanding bladder -- we had constant-volume altitude stabilization at 30,000 feet. Flight duration was long as expected -- about 5 hours.

Our 15m radio astronomy sytem responds to changes in D-layer density. If the greyline(grey area on the map) is above TAO then we get terrestrial transmitter interference in our Skypipe Jupiter/Solar monitor receiver. Signals which travel inside the grayline region often experience significant improvements in propagation because of the loss of ionization in the D-region as the Sun sets. However, because the higher F-regions of the ionosphere remain strongly ionized for longer periods of time, signals with higher frequencies are able to travel to greater distances with less attenuation when they are within the grayline. The current solar position is shown in the yellow area. Click on the image for more informaton.

TAO proudly supports the NASA Night Sky Network through our associated astronomy clubs in Oak Ridge, Knoxville, and Soddy Daisy
