Next BAS Monthly Meeting:
Monday, June 2 at 7:00 p.m. at the library in meeting room C (not Bartlesville High School as originally posted)
Our presentation will be "Moonwatch and the Early Days of the Bartlesville Astronomical Society"
By Ron Carman
The Bartlesville Astronomical Society has a long and rich history, which began as a consequence of a Cold War citizen defense project called “Operation Moonwatch”, a program that encouraged thousands of U.S. citizens to watch the night skies for Soviet bombers and satellites. In 1958 Bartlesville established its own Moonwatch station, which the Examiner-Enterprise described as “the result of the perseverance for more than a year of 12 or 14 College High School and Central High School students”. Our special speaker tonight is one of those very students! He will describe their efforts out in the cow pasture, watching the night skies for anything suspicious, which ultimately led to the creation of the Bartlesville Astronomical Society!
Club members will be sent a link to the Zoom meeting. Here is a link to the Join page on our website! If you are not a Club member but would like to attend, please email bvilleastro@gmail.com and ask to have the Zoom link sent to you!
BAS meetings feature presentations on a variety of astronomy and space science topics. Meetings are usually on the first Monday evening of each month and are open to the public. Guests are always welcome. More event details are listed on our calendar.

Have you ever found a hairline crescent Moon as young as 24 hours from new? You get a chance Tuesday after sunset. Mars fades, Jupiter says goodbye, and a globular cluster waits for you in the Keystone.

The discovery of a barred spiral galaxy in a universe just a couple billion years old suggests that galaxies formed and evolved much more quickly than current theories suggest.

Astronomers have watched clouds move in Titan's atmosphere and even observed the chemistry of Saturn's moon in action.

The story of Messier object No. 40 not only makes for a great yarn, but it also demonstrates the haphazard nature of scientific progress.

Mysterious threads dangle in the Milky Way center, and a pulsar has punched through one of them — providing fresh perspective on the threads' origins.

Titan shadow transits are rare, occurring only about every 15 years. Don't miss the chance to see one this observing season.

Astronomers who tracked a roaming magnetar for over a decade found that it didn’t originate from a supernova, making its origins an open question.

The sub-Neptune TOI-421b is made of much the same stuff as its star — matching predictions, but bucking the trend among other similarly sized planets.

Small relatives of the much-larger Kalliope, a metallic main-belt asteroid shed light on their mutual origin early in solar system history.

A new look at the galaxies swarming around the Andromeda Galaxy shows that their asymmetric arrangement is rare — and difficult to explain.

While you won't see a trace of this exoplanet or alien life, it's easy to spot the red dwarf star that warms its surface.

Astronomy Calendar of Celestial Events
(Source: http://www.seasky.org/astronomy/astronomy-calendar-current.html)
May 27 - 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 03:04 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.
May 31 - Venus at Greatest Western 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 morning sky. Look for the bright planet in the eastern sky before sunrise.
June 11 - 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 07:45 UTC. This full moon was known by early Native American tribes as the Strawberry Moon because it signaled the time of year to gather ripening fruit. It also coincides with the peak of the strawberry harvesting season. This moon has also been known as the Rose Moon and the Honey Moon.
June 21 - June Solstice. The June solstice occurs at 02:40 UTC. The North Pole of the earth will be tilted toward the Sun, which will have reached its northernmost position in the sky and will be directly over the Tropic of Cancer at 23.44 degrees north latitude. This is the first day of summer (summer solstice) in the Northern Hemisphere and the first day of winter (winter solstice) in the Southern Hemisphere.
June 25 - 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 10:33 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.
July 4 - Mercury at Greatest Eastern Elongation. The planet Mercury reaches greatest eastern elongation of 25.9 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 evening sky. Look for the planet low in the western sky just after sunset.
July 10 - 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 20:38 UTC. This full moon was known by early Native American tribes as the 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 Thunder Moon and the Hay Moon.
July 24 - 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 19:13 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.
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 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 Aquarius, but can appear anywhere in the sky.
August 9 - 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 07:56 UTC. This full moon was known by early Native American tribes as the 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 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 waning gibbous moon will block out all but the brightest meteors this year. But if you are patient, you may still be able to catch quite a few good ones. 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 19 - Mercury at Greatest Western Elongation. The planet Mercury reaches greatest western elongation of 18.6 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.
August 23 - 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 06:08 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.
