Program:

"Voyager"

by

Evan Zorn

Evan's program was originally scheduled for July 2, but due to technological problems, it has been rescheduled for August 6.

Meetings are open to the public and guests are welcome.

The earliest written records were astronomical observations. The history of astronomy since then has been a complex interplay of philosophy and science. From ancient history to more recent times, read on to explore the history of astronomy.

Hi All,

Please see the email below from Tamara Green, president of the Astronomy Club of Tulsa, in regards to the Astronomy Day at Woolaroc on Aug. 18th. Looks like it will run from noonish to about 10 pm. I know at least one of you who said they could help, but I hope a few more of us will sign up. I plan on being there at least for part of the day and maybe for the whole time. If you would, please let Ms. Green and I know if you would be willing to help so that we can come up with a game plan for the day. Also, if you have any ideas for some activities to do during the day, please let us know.

Thanks, Karen Cruce, President, BASDear Ms. Cruce:

My name is Tamara Green, and I am the President of the Astronomy Club of Tulsa.

Jan Tucker with Woolaroc recently contacted me about our club doing an "Astronomy Day" at Woolaroc sometime this summer. Our club chose Saturday, August 18.

She said we could also invite your club to participate with us.

We plan to arrive at Woolaroc on that day at either Noon or 1:00 PM and have some astronomy-related activities during the day, followed by a talk on astronomy equipment in their Events Center at 6:30 PM. Then at 7:00 PM, even though the sun will still be up, guests could view the 1st Quarter Moon, which rises at 2:23 PM. When it gets darker after sundown, there will be Venus and Jupiter.

They want us to start breaking down at 9:00 PM, and be off the property by 10:00 PM.

Does this sound like something the Bartlesville club would be interested in participating in? If so, you all are welcome to come up with some daytime activities for the event as well! We would love to have you guys participate with us if you can!

If you need to contact me, my email address is astrotulsa.pres@gmail.com, and my phone number is (918) 851-1213.

I look forward to hearing from you!

Clear Skies!

Tamara Green

President

Hello BAS Members --

With so many people interested in AstroPhotography in the group, we have thought of having a "Astro Picture of the Month" competition each month at our meetings.

Entry Rules:

Send one picture of the night sky/ object of the current month with a description of the picture and the equipment used to take this.

Mail it to bvilleastro@gmail.com.

Astronomers have conducted the best, galaxy-scale test of general relativity yet, and it rules out some (but not all) theories of modified gravity.

Skyweek

July 27 - Full Moon. The Moon will be located on the opposite side of the Earth as the Sun and its face will be will be fully illuminated. This phase occurs at 20:22 UTC. This full moon was known by early Native American tribes as the Full Buck Moon because the male buck deer would begin to grow their new antlers at this time of year. This moon has also been known as the Full Thunder Moon and the Full Hay Moon.

July 27 - Total Lunar Eclipse. A total lunar eclipse occurs when the Moon passes completely through the Earth's dark shadow, or umbra. During this type of eclipse, the Moon will gradually get darker and then take on a rusty or blood red color. The eclipse will be visible throughout most of Europe, Africa, western and central Asia, the Indian Ocean, and Western Australia. (NASA Map and Eclipse Information)

July 27 - Mars at Opposition. The red planet will be at its closest approach to Earth and its face will be fully illuminated by the Sun. It will be brighter than any other time of the year and will be visible all night long. This is the best time to view and photograph Mars. A medium-sized telescope will allow you to see some of the dark details on the planet's orange surface.

July 28, 29 - Delta Aquarids Meteor Shower. The Delta Aquarids is an average shower that can produce up to 20 meteors per hour at its peak. It is produced by debris left behind by comets Marsden and Kracht. The shower runs annually from July 12 to August 23. It peaks this year on the night of July 28 and morning of July 29. The nearly full moon will be a problem this year, blocking out all but the brightest meteors. But if you are patient, you should still be able to catch a few good ones. Best viewing will be from a dark location after midnight. Meteors will radiate from the constellation Aquarius, but can appear anywhere in the sky.

August 11 - New Moon. The Moon will located on the same side of the Earth as the Sun and will not be visible in the night sky. This phase occurs at 09:58 UTC. This is the best time of the month to observe faint objects such as galaxies and star clusters because there is no moonlight to interfere.

August 11 - Partial Solar Eclipse. A partial solar eclipse occurs when the Moon covers only a part of the Sun, sometimes resembling a bite taken out of a cookie. A partial solar eclipse can only be safely observed with a special solar filter or by looking at the Sun's reflection. The partial eclipse will be visible in parts of northeast Canada, Greenland, extreme northern Europe, and northern and eastern Asia. It will be best seen in northern Russia with 68% coverage. (NASA Map and Eclipse Information)

August 12, 13 - Perseids Meteor Shower. The Perseids is one of the best meteor showers to observe, producing up to 60 meteors per hour at its peak. It is produced by comet Swift-Tuttle, which was discovered in 1862. The Perseids are famous for producing a large number of bright meteors. The shower runs annually from July 17 to August 24. It peaks this year on the night of August 12 and the morning of August 13. The thin crescent moon will set early in the evening leaving dark skies for what should be an excellent show. Best viewing will be from a dark location after midnight. Meteors will radiate from the constellation Perseus, but can appear anywhere in the sky.

August 17 - Venus at Greatest Eastern Elongation. The planet Venus reaches greatest eastern elongation of 45.9 degrees from the Sun. This is the best time to view Venus since it will be at its highest point above the horizon in the evening sky. Look for the bright planet in the western sky after sunset.

August 26 - Full Moon. The Moon will be located on the opposite side of the Earth as the Sun and its face will be will be fully illuminated. This phase occurs at 11:57 UTC. This full moon was known by early Native American tribes as the Full Sturgeon Moon because the large sturgeon fish of the Great Lakes and other major lakes were more easily caught at this time of year. This moon has also been known as the Green Corn Moon and the Grain Moon.

August 26 - Mercury at Greatest Western Elongation. The planet Mercury reaches greatest western elongation of 18.3 degrees from the Sun. This is the best time to view Mercury since it will be at its highest point above the horizon in the morning sky. Look for the planet low in the eastern sky just before sunrise.

September 7 - Neptune at Opposition. The blue giant planet will be at its closest approach to Earth and its face will be fully illuminated by the Sun. It will be brighter than any other time of the year and will be visible all night long. This is the best time to view and photograph Neptune. Due to its extreme distance from Earth, it will only appear as a tiny blue dot in all but the most powerful telescopes.

September 9 - New Moon. The Moon will located on the same side of the Earth as the Sun and will not be visible in the night sky. This phase occurs at 18:01 UTC. This is the best time of the month to observe faint objects such as galaxies and star clusters because there is no moonlight to interfere.

September 23 - September Equinox. The September equinox occurs at 01:54 UTC. The Sun will shine directly on the equator and there will be nearly equal amounts of day and night throughout the world. This is also the first day of fall (autumnal equinox) in the Northern Hemisphere and the first day of spring (vernal equinox) in the Southern Hemisphere.

September 25 - Full Moon. The Moon will be located on the opposite side of the Earth as the Sun and its face will be will be fully illuminated. This phase occurs at 02:53 UTC. This full moon was known by early Native American tribes as the Full Corn Moon because the corn is harvested around this time of year. This moon is also known as the Harvest Moon. The Harvest Moon is the full moon that occurs closest to the September equinox each year.
