An Open Invitation

For amateur radio operators and scanner enthusiasts around the world, please join the Colorado Astronomy Net on the Rocky Mountain Radio League's K1DUN 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.

The Colorado Astronomy Net is now on YouTube!!
All are welcome to join us Tuesday evenings!

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. All others interested in Amateur Radio, check out the Amateur Radio Relay League website to find out more information about becoming an Amateur Radio operator.

Astronomy Calendar 2026: All Major Celestial Events of the Year

The Planets & Dwarf Planets

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.

Note: Due to DST beginning for most of the U.S. this month, times on the 1st are MST, times at the end of the month are MDT.

Planetary Highlights for April

"Exciting planetary action takes place this month. Venus and Uranus vie for attention and lie close to each other in late April. Jupiter offers a lot to observe through a telescope, particularly events involving its Galilean moons. The rest of the action takes place just before dawn, with Mars, Mercury, and Saturn making an appearance in late April. And remember to take time out to watch the Lyríd meteor shower, with no Moon to interfere." Astronomy Magazine, April 2026, p.28.

Mercury

Is at greatest western elongation (28°) on the 3rd. Mercury rises at 5:46 a.m. on the 1st and about 5:33 a.m. by month's end. Mercury is visible in the eastern sky about 30 minutes before sunrise. Mercury moves from the constellation of Aquarius into Pisces shining at magnitude 0.4 on the 1st.

Venus

Sets about 9:06 p.m. on the 1st and about 10:16 p.m. by month's end. Look for Venus to the west about an 30 minutes after sunset. Venus moves from the constellation of Aries into Taurus shining at magnitude -3.9.

Earth

N/A.

Mars

Rises at 6:07 a.m. on the 1st and about 5:03 a.m. by month's end. Look for Mars low to the east in the morning about 30 minutes before sunrise. Mars moves from the constellation of Aquarius into Pisces shining at magnitude 1.2.

Jupiter

Sets at 2:55 a.m. on the 1st and about 1:09 a.m. by month's end. By the time the Sun sets, Jupiter is high in the southern sky and dominates the rest of the night until it sets in the early morning hours before dawn. Jupiter is in the constellation of Gemini shining at magnitude -2.1.

Saturn

Rises at 6:41 a.m. on the 1st and about 4:51 a.m. by month's end. Look for Saturn towards the east in the morning sky, before sunrise. Saturn moves from the constellation of Pisces into Cetus shining at magnitude 0.9.

Uranus

Sets about 11:16 p.m. on the 1st and about 9:26 p.m. by month's end. Look for Uranus to the southwest in the evening. Uranus is in the constellation Taurus shining at magnitude 5.8.

Neptune

Rises at 6:29 a.m. on the 1st and about 4:33 a.m. by month's end. Look for Neptune towards the east in the morning sky, before sunrise. Neptune is in the constellation of Pisces shining at magnitude 7.8.

Dwarf Planets

Ceres

Sets at 10:16 p.m. on the 1st and about 8:19 p.m. by month's end. Ceres can be spotted low to the west once the skies darken after sunset. Ceres moves from the constellation of Cetus into Aries shining at magnitude 8.9.

Pluto

Rises at 4:12 a.m. on the 1st and about 2:15 a.m. by month's end. Pluto can be spotted to the southeast before sunrise. Pluto is in the constellation of Capricornus shining at magnitude 15.3.

As always, good luck at spotting Neptune, Ceres and Pluto, a large telescope and dark skies will be needed.

Astronomical Events

Meteor Showers

  • The Lyrids meteor showers are typically visible between April 16 and 25. Maximum occurs during April 21-22. Although the maximum rate is about 10, there have been instances during the last 200 years when rates were near or over 100 per hour. The average magnitude of the meteors is near 2.4 and the speed is described as rapid. About 15% of the meteors leave persistent trains.

    For more information about Meteor Showers, visit the Meteor Showers Online web page.

    Meteor Shower Radiant Report

    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.

    Meteor Rx How-To by Terry Bullett (WØASP)

  • Comets

  • Comet C/2024 E1 (Wierzchoś) continues its ascent for northern hemisphere observers, passing between Taurus and Orion in the evening sky soon after sunset. Dimming to 10th magnitude, it will be difficult to spot to the west even under optimal conditions.

  • Comet 10/P Temple (Temple 2) is brightening to about 9th magnitude passing through the Scutum Star Cloud, near the globular cluster NGC 6712.

  • Comet C/2025 R3 (PanSTARRS) is crossing the square of Pegasus around mid-month, in binocular view, but do it quickly before it disappears a week later.

  • For information, orbital elements and ephemerides on observable comets, visit Observable Comets.

    For more information about Comets, check out Gary Kronk's 6-volume series of books on Cometography.

  • Eclipses

    Solar Eclipses

    No solar eclipse activity this month.

    Lunar Eclipses

  • No lunar eclipse activity this month.

  • Observational Opportunities

  • Look for Venus, Ceres and Uranus to the southwest.
  • Look for Jupiter in the evening and early morning to the south.
  • Look for Neptune, Saturn, Pluto, Mars and Mercury in the early morning to the east.

  • Asteroids

    (From west to east)
    • Iris is in the constellation of Leo.
    • Massalia is in the constellation of Virgo.

    Member Meteor Sightings

    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.
