For amateur radio operators and scanner enthusiasts around the world, please join the Colorado Astronomy Net on the Rocky Mountain Radio League'sK1DUN repeater on 449.450 MHz or other digital and analog repeaters, Allstar nodes, Echolinks, DMR and internet links connected to the SKYHUBLINK system. The net meets on Tuesday nights at 7 P.M. Mountain Time (US) (Wednesday at 0200 GMT). Connecting to the SkyHubLink system has expanded our coverage in the U.S., Canada and internationally. All Amateur radio operators worldwide are welcome. Anyone may listen to the net. The RMRL provides a "Live Audio Feed" using Broadcastify.
Obtain your Amateur Radio (Ham) License or your General Radio Operator's License (GROL)! Visit the South Metro VE Team website for more information. The South Metro VE Team provides test sessions by appointment only. Check the website for current information.

Planetary Reports generated by "TheSkyX" software. These reports provide predicted data for the planets for the first of each month for the current year. The rise and set times for the Sun and the Moon for each day of the month as well as meteor shower radiants are also included in the reports. These reports have been optimized for the Denver, Colorado location, however, the times will be approximate for other locations on Earth.
(Times are Mountain Daylight Time (MDT) unless otherwise noted. Times will vary slightly depending on your location.)
"Venus lingers after sunset. Saturn reaches opposition Sept. 8 and Neptune reaches opposition on the 20th. Jupiter dominates Taurus and Mars improves as it passes into Gemini. Mercury makes its best morning appearance in the Northern Hemisphere and the last week of September could offer a naked-eye comet." Astronomy Magazine, September 2024, p. 28.
Is at greatest western elongation (18°) on the 4th. Mercury is in superior conjunction on the 30th. Mercury rises at 5:05 a.m. on the 1st. Mercury is visible about 30 minutes before sunrise during the first two weeks of the month. After conjunction, Mercury returns to the evening sky setting about 6:48 p.m. by month's end. Mercury moves from the constellation of Leo into Virgo shining at magnitude 0.5 on the 1st.
Sets about 8:31 p.m. on the 1st and about 7:59 p.m. by month's end. Look for Venus low to the west about 30 minutes after sunset. Venus moves from the constellation of Virgo into Libra shining at magnitude -3.9 on the 15th.
Rises at 12:39 a.m. on the 1st and about 11:55 p.m. by month's end. Look for Mars to the south before sunrise. Mars moves from the constellation of Taurus into Gemini shining at magnitude 0.6.
Rises at 12:06 a.m. on the 1st and about 10:13 p.m. by month's end. Look for Jupiter to the south before sunrise. Jupiter is in the constellation of Taurus shining at magnitude -2.3.
Is at opposition on the 8th. Saturn rises at 7:48 p.m. on the 1st and about 5:45 p.m. by month's end. Saturn is at its best for the year. Follow Saturn across the sky all night long. Saturn is in the constellation of Aquarius shining at magnitude 0.6.
Is at opposition on the 20th. Neptune rises at 8:14 p.m. on the 1st and about 6:14 p.m. by the month's end. Neptune is at its best for the year. Follow Neptune across the sky all night long. Neptune is in the constellation of Pisces shining at magnitude 7.7.
Rises at 4:44 p.m. on the 1st and about 3:00 p.m. by month's end. Ceres is visible in the evening sky to the south and southwest. Ceres is in the constellation of Sagittarius shining at magnitude 8.7.
Rises at 5:45 p.m. on the 1st and about 3:46 p.m. by month's end. Pluto is visible to the south and southwest late evening and early morning sky. Pluto is in the constellation of Capricornus shining at magnitude 15.2.
As always, good luck at spotting Neptune, Ceres and Pluto, a large telescope and dark skies will be needed.

"There are no meteor showers during September. However, a pre-dawn glow caused by millions of tiny dust particles filling our inner solar system can be observed on clear moonless nights from very dark locations. This zodiacal light shines with similar or a bit fainter brilliance than the Milky Way and is located along the ecliptic, which is angled steeply to the horizon this month, improving your chances of seeing it.
The zodiacal light is a faint cone-shaped glow with a broad base in Leo that narrows higher in the sky through Cancer and Gemini. With a New Moon on the 2nd, the first two weeks of September are the most favorable time this month to view this elusive phenomenon. Any glow from cities to your east will limit the view." Astronomy Magazine, September 2024, p. 29.

Meteor Scatter (or Meteor burst communications) - "is a radio propagation mode that exploits the ionized trails of meteors during atmospheric entry to establish brief communications paths between radio stations up to 2,250 kilometres (1,400 mi) apart." Tune your shortwave or your HF amateur radio to 54.310 MHz SSB and see if you can hear any pings. Try other frequencies as well... 6m FT8 digital - 50.313 Mhz & 50.276 Mhz, JP-65 digital mode and the carrier frequencies of the lower VHF bands for TV channels 2, 3 & 4.
Comet13P/Olbers passes through the constellation of Coma Berenices, Bootes and Virgo, about 15° above the northwest horizon shining around 9th magnitude soon after sunset. A 4-inch scope, dark skies and a clear northwest horizon will be needed to see this comet before it disappears.

In this section I will post meteor, fireball, etc sightings that have been published on the American Meteor Society's web site. I want to make this an active section of the web pages and newsletter and would like to publish the links to member sightings. If you have any published sightings, please provide me with the links and I will post them here for all to enjoy.
I have created a web page containing images taken and submitted by subscribers (or special images) to the email newsletter, check-ins to the Colorado Astronomy Net and readers of the online newsletter. Any one wishing to submit their own images to the gallery, please let me know. The images must be taken by the submitter and be astronomy related. Please include a description and your information so that I can give proper credit to your work.

"Earth's Moon is the brightest and largest object in our night sky. The Moon makes Earth a more livable planet by moderating our home planet's wobble on its axis, leading to a relatively stable climate. It also causes tides, creating a rhythm that has guided humans for thousands of years.
The Moon was likely formed after a Mars-sized body collided with Earth several billion years ago.
Earth's only natural satellite is simply called "the Moon" because people didn't know other moons existed until Galileo Galilei discovered four moons orbiting Jupiter in 1610. In Latin, the Moon was called Luna, which is the main adjective for all things Moon-related: lunar." NASA Science
