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 is a bright evening star for a short period after sunset, beckoning skywatchers to view the oncoming string of planets. Saturn puts on a great show when it rises in the late evening. You can also grab a pair of binoculars to spy Uranus and Neptune... The real spectacle of the month is the conjunction of Jupiter and Mars in Taurus on the 14th, visible in the early-morning hours. It's one sight you won't want to miss." Astronomy Magazine, August 2024, p. 28.
Is stationary on the 4th. Mercury is in inferior conjunction on the 18th. Mercury is again stationary on the 27th. Mercury sets at 9:00 p.m. on the 1st. After conjunction, Mercury returns to the morning sky, rising about 5:05 a.m. by month's end. Look for Mercury low on the western horizon about 30 minutes after sunset during the first week of the month, and then to the east about 30 minutes before sunrise during the last week of the month. Mercury is in the constellation of Leo shining at magnitude 0.7 on the 31st.
Sets about 9:03 p.m. on the 1st and about 8:31 p.m. by month's end. Look for Venus low to the west about 30 minutes after sunset. Venus moves from the constellation of Leo into Virgo shining at magnitude -3.9 on the 15th.
Rises at 1:25 a.m. on the 1st and about 12:39 a.m. by month's end. Look for Mars to the southeast before sunrise. Mars in is conjunction with Jupiter on the 14th. Mars is in the constellation of Taurus shining at magnitude 0.8.
Rises at 1:50 a.m. on the 1st and about 12:06 a.m. by month's end. Look for Jupiter to the southeast before sunrise. Jupiter is in the constellation of Taurus shining at magnitude -2.2.
Rises at 9:55 p.m. on the 1st and about 7:48 p.m. by month's end. Look to the south-southwest to spot Saturn late evening/early morning before sunrise. Saturn is in the constellation of Aquarius shining at magnitude 0.7.
Rises at 12:46 a.m. on the 1st and about 10:42 p.m. by month's end. Look to the south to spot Uranus preceding Jupiter by about an hour or so. Uranus is in the constellation of Taurus shining at magnitude 5.8.
Rises at 10:17 p.m. on the 1st and about 8:14 p.m. by the month's end. Look for Neptune before sunrise to the south. Neptune trails Saturn by about a half hour. Neptune is in the constellation of Pisces shining at magnitude 7.7.
Is stationary on the 26th. Ceres rises at 6:52 p.m. on the 1st and about 4:44 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 8.2.
Rises at 7:49 p.m. on the 1st and about 5:45 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 15.1.
As always, good luck at spotting Neptune, Ceres and Pluto, a large telescope and dark skies will be needed.

The Northern Delta Aquarids [meteor shower] extends from July 16 to September 10. Maximum occurs on August 13. The hourly rates reach a high of 10.
The Perseids meteor shower is generally visible between July 23 and August 22. Maximum occurs during August 12/13. The hourly rate typically reaches 80, although some years have been as low as 4 and as high as 200. The meteors tend to be very fast, possess an average magnitude of 2.3 and leave persistent trains.
"The Perseid Meteor Shower is favorable this year. The First Quarter Moon sets around midnight, offering hours of viewing in a dark sky when we are on the leading hemisphere of Earth as we orbit the Sun. As we plow into the stream, we'll see higher-velocity - and therefore brighter - meteors.
The shower, a result of Comet 109P/Swift-Tuttle, is active from July 17 to Aug. 24 and peaks Aug. 12. Both the mornings of Aug. 11 and 12 should provide good rates; if poor weather is around, try Aug. 10 and 13 as well." Astronomy Magazine, August 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.
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.

M17 - Omega/Horseshoe Nebula Courtesy of Roy Murray (KI7PKL)
M17, aka The Horseshoe Nebula, aka The Omega Nebula is located in the southern sky, in the constellation of Sagittarius. That constellation is so far south that one may have to catch it as it passes between the treetops. But that part of the sky is full of treasures, and well worth the effort. This was taken in early July 2024, with approximately five hours of data in 1 minute exposures, using my new SkyWatcher HEQ-5 mount and an ASI294MC Pro cooled astronomy camera.
Attention!! I will be eliminating the JPL and Mars stories from this section in the future. I will still provide the links to the missions but not the articles themselves. I do appreciate everyone's support after 25+ years of publishing this newsletter. Thank you!
"Today, enormous stretches of space are crystal clear, but that wasn't always the case. During its infancy, the universe was filled with a "fog" that made it opaque, cloaking the first stars and galaxies. NASA's upcoming Nancy Grace Roman Space Telescope will probe the universe's subsequent transition to the brilliant starscape we see today — an era known as cosmic dawn.
"Something very fundamental about the nature of the universe changed during this time," said Michelle Thaller, an astrophysicist at NASA's Goddard Space Flight Center in Greenbelt, Maryland. "Thanks to Roman's large, sharp infrared view, we may finally figure out what happened during a critical cosmic turning point." "
Read the latest news and discoveries from JPL's dozens of active space missions exploring Earth, the solar system and worlds beyond.
"An international team of astronomers using NASA's James Webb Space Telescope has directly imaged an exoplanet roughly 12 light-years from Earth. The planet, Epsilon Indi Ab, is one of the coldest exoplanets observed to date.
Article & Images
The planet is several times the mass of Jupiter and orbits the K-type star Epsilon Indi A (Eps Ind A), which is around the age of our Sun, but slightly cooler. The team observed Epsilon Indi Ab using the coronagraph on Webb's MIRI (Mid-Infrared Instrument). Only a few tens of exoplanets have been directly imaged previously by space- and ground-based observatories."
"During its 61st close flyby of Jupiter on May 12, 2024, NASA's Juno spacecraft captured this color-enhanced view of the giant planet's northern hemisphere. It provides a detailed view of chaotic clouds and cyclonic storms in an area known to scientists as a folded filamentary region. In these regions, the zonal jets that create the familiar banded patterns in Jupiter's clouds break down, leading to turbulent patterns and cloud structures that rapidly evolve over the course of only a few days."
"Using observations by NASA's TESS (Transiting Exoplanet Survey Satellite) and many other facilities, two international teams of astronomers have discovered a planet between the sizes of Earth and Venus only 40 light-years away. Multiple factors make it a candidate well-suited for further study using NASA's James Webb Space Telescope.
TESS stares at a large swath of the sky for about a month at a time, tracking the brightness changes of tens of thousands of stars at intervals ranging from 20 seconds to 30 minutes. Capturing transits — brief, regular dimmings of stars caused by the passage of orbiting worlds — is one of the mission's primary goals."

JMARS is an acronym that stands for Java Mission-planning and Analysis for Remote Sensing. It is a geospatial information system (GIS) developed by ASU's Mars Space Flight Facility to provide mission planning and data-analysis tools to NASA's orbiters, instrument team members, students of all ages, and the general public.
"The lofting and transport of dust particles, which can be electrically charged and thus mobilized, pose a potential hazard to future lunar exploration. Dust particles can cover the surfaces of optical instruments, damage space suits, and degrade solar panels, as well as pose health risks if inhaled by astronauts.
While there is strong evidence that the lofting and transport of charged dust may occur on all airless bodies across our solar system and can dramatically reshape their surfaces, no missions have yet explored this phenomenon away from the lunar surface. On small bodies such as asteroids, Martian moons, and dormant comets, due to their low gravity, lofted dust particles are expected to be transported on a global scale or even escape from their parent bodies."
"The Sun will be at peak activity this year, providing a rare opportunity to study how solar storms and radiation could affect future astronauts on the Red Planet.
In the months ahead, two of NASA's Mars spacecraft will have an unprecedented opportunity to study how solar flares — giant explosions on the Sun's surface — could affect robots and future astronauts on the Red Planet.
That's because the Sun is entering a period of peak activity called solar maximum, something that occurs roughly every 11 years. During solar maximum, the Sun is especially prone to throwing fiery tantrums in a variety of forms — including solar flares and coronal mass ejections — that launch radiation deep into space. When a series of these solar events erupts, it's called a solar storm."
"The six-wheeled geologist found a fascinating rock that has some indications it may have hosted microbial life billions of years ago, but further research is needed.
A vein-filled rock is catching the eye of the science team of NASA's Perseverance rover. Nicknamed "Cheyava Falls" by the team, the arrowhead-shaped rock contains fascinating traits that may bear on the question of whether Mars was home to microscopic life in the distant past.
Analysis by instruments aboard the rover indicates the rock possesses qualities that fit the definition of a possible indicator of ancient life. The rock exhibits chemical signatures and structures that could possibly have been formed by life billions of years ago when the area being explored by the rover contained running water. Other explanations for the observed features are being considered by the science team, and future research steps will be required to determine whether ancient life is a valid explanation."
"Among several recent findings, the rover has found rocks made of pure sulfur — a first on the Red Planet.
Scientists were stunned on May 30 when a rock that NASA's Curiosity Mars rover drove over cracked open to reveal something never seen before on the Red Planet: yellow sulfur crystals.
Since October 2023, the rover has been exploring a region of Mars rich with sulfates, a kind of salt that contains sulfur and forms as water evaporates. But where past detections have been of sulfur-based minerals — in other words, a mix of sulfur and other materials — the rock Curiosity recently cracked open is made of elemental, or pure, sulfur. It isn't clear what relationship, if any, the elemental sulfur has to other sulfur-based minerals in the area."
"There's good news from NASA's Cloudspotting on Mars project! That's the project that invites you to help identify exotic clouds high in the Martian atmosphere.
Thanks to your help, the Cloudspotting on Mars project reached a huge milestone. Another full Mars year, Mars Year 30 (Oct 2009 — Sep 2011), has been completed! That's the second full Mars year of observations that has been analyzed since the project began.
A new project from the Cloudspotting on Mars team has started its beta testing phase! In this new project, you'll pick out cloud shapes in data from NASA's Mars Atmosphere and Volatile Evolution (MAVEN) Mission. If you're willing to help beta test this project and provide feedback before it launches, please send an email to the team. We'll let everyone know when this project officially launches, of course!
Congratulations to the Cloudspotting on Mars team and all the volunteers who have helped spot Martian clouds!"
"The 23-year-old orbiter is taking images that offer horizon-wide views of the Red Planet similar to what astronauts aboard the International Space Station see over Earth.
NASA's longest-lived Mars robot is about to mark a new milestone on June 30: 100,000 trips around the Red Planet since launching 23 years ago. During that time, the 2001 Mars Odyssey orbiter has been mapping minerals and ice across the Martian surface, identifying landing sites for future missions, and relaying data to Earth from NASA's rovers and landers.
Scientists recently used the orbiter's camera to take a stunning new image of Olympus Mons, the tallest volcano in the solar system. The image is part of a continuing effort by the Odyssey team to provide high-altitude views of the planet's horizon. (The first of these views was published in late 2023.) Similar to the perspective of Earth astronauts get aboard the International Space Station, the view enables scientists to learn more about clouds and airborne dust at Mars."
