TAO Public Stargaze

October 18, 2014

Gates open at 7:30 PM

 

We plan an evening exploring the world's greatest nature park. The moon will be almost 'new', rising after midnight. Mars should be visible for a few minutes before setting, but Saturn will be far in the west, difficult to find.

Date Saturn sets:
Sept. 19 2107h
Oct. 19 1919h
Nov. 18 1732h

Where are we? See our map.

 

We'll welcome Roane State faculty member Katheryne Nix and her girl's youth group. This will be a great night for the kits at TAO. 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.

We're continuing to have good skies with the Milky Way bright overhead and lots of deep-sky objects to be seen.

Telescope making/mirror grinding is an activity of study for astronomy labs, plus a hands-on activity for everyone (students, amateur astronomers and visitors). Here is a December photo:

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 home. 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 Civic Center on third Wednesday evenings at 1900 h (7:00 PM).

Astronomers from the Oak Ridge Isochronous Observation Network (ORION) and the Smokey Mountain Astronomical Society (SMAS) groups participate in most TAO 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.

Solar Photos

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

This (below) is an earlier photo of (multiple science fair award winner) Katie Sloop, together with the visiting Dinkins family, learning radio astronomy at TAO.


 

We had a welcome to guests followed by a classroom presentation at 1930 h on our 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 Yajit Jain, Carlos del-Castillo-Negrete, and Scotty Chung. 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.


Radio Astronomy is one focus ofour classroom and activities. Here is an image of a poster showing how we are using the Itty Bitty Telescope (IBT) as part of the SARA-NRAO Radio Navigator's Group (click for full size, and we are happy to share the poster).

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

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

 

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.

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
