Next Observing Event: Stargazing at the Library, Wednesday, July 2, 8:15 p.m., weather permitting.
The Moon will be a little less than first quarter. At that phase, the terminator will create some dramatic shadows that will highlight the craters and mountains. As it gets darker, Mars will be high in the southwest and Mercury will be low in the west. In addition, Arcturus will be high in the southeast and Vega will be rising in the northeast.
Next BAS Monthly Meeting:
Monday, July 7 at 7:00 p.m. at the library in meeting room C
Our presentation will be on Northern Lights, which have been seen in Bartlesville
Speaker: Denise Gregg
Denise will discuss how Northern Lights come to be, with case studies from the Northern Lights that were visible in Oklahoma in May and October 2024. She will also discuss other phenomena that can appear along with Northern Lights. Photographs demonstrating the different colors of Northern Lights will accompany explanations of what we know about what causes differnet colors. In addition, the program will include two videos showing over eight hours total of Northern lights photography, condensed into about two minutes.
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!

Astronomy Calendar of Celestial Events
(Source: http://www.seasky.org/astronomy/astronomy-calendar-current.html)
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.
Next Month's BAS Meeting: August 4, Monday. Presenter: TBA
