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 KIØGO 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: Times are Mountain Time (MDT) unless otherwise noted. Times will vary slightly depending on your location.

Planetary Highlights for October

"Saturn reaches opposition this month, putting on a fine show. Mercury is briefly visible early in October, while Venus remains low after sunset. Neptune lingers near Saturn, and Uranus is well placed between the Pleiades and Aldebaran. Mars makes a magnificent transit of the Beehive Cluster, not to be missed. Jupiter dominates the morning sky and undergoes a lunar occultation." Astronomy Magazine, October 2026, p.28.

Mercury

Is at greatest eastern elongation (25°) on the 12th. Mercury is stationary on the 24th. Mercury sets at 7:29 p.m. on the 1st and about 5:08 p.m. by month's end. Mercury is visible in the western sky about 30 minutes after sunset during the first three weeks of October. Mercury moves from the constellation of Virgo into Libra shining at magnitude 0.1 on the 15th. Sets at 7:49 p.m. on the 1st and about 7:29 p.m. by month's end. Mercury is visible in the western sky about 30 minutes after sunset after the first week of September. Mercury moves from the constellation of Leo into Virgo shining at magnitude -0.1 on the 30th.

Venus

Is stationary on the 2nd. Venus is in inferior conjunction on the 23rd. Venus sets about 7:20 p.m. on the 1st. After conjunction, Venus returns to the morning sky, rising about 5:32 a.m. by month's end. Look for Venus to the west about 30 minutes after sunset during the first half of the month. Venus is in the constellation of Virgo shining at magnitude -4.8 on the 1st.

Earth

ends for most of the U.S. at 2 a.m. local time November 1, 2026.

Mars

Rises at 1:21 a.m. on the 1st and about 11:42 p.m. by month's end. Look for Mars to the south in the morning before sunrise. Mars transits the Beehive cluster (M44) on the morning of the 11th well before dawn. Mars moves from the constellation of Cancer into Leo shining at magnitude 1.0.

Jupiter

Rises at 2:53 a.m. on the 1st and about 12:15 a.m. by month's end. Jupiter is visible to the southeast in the morning sky before sunrise. Jupiter is occulted by the Moon on the 6th. This occultation is visible in the eastern U.S. beginning around 4:20 a.m. EDT. Jupiter is in the constellation of Leo shining at magnitude -1.9.

Saturn

Is at opposition on the 4th, rising as the Sun sets. Saturn rises at 6:54 p.m. on the 1st and about 3:46 p.m. by month's end. Saturn is at its best viewing for the year this month. Look for Saturn towards the east in the evening sky after sunset and follow it across the sky all night. Saturn is in the constellation of Cetus shining at magnitude 0.3.

Uranus

Rises at 9:13 p.m. on the 1st and about 6:09 p.m. by month's end. Look for Uranus to the east in the evening and follow it too across the sky all night. Uranus is in the constellation Taurus shining at magnitude 5.6.

Neptune

Rises at 6:27 p.m. on the 1st and about 3:24 p.m. by month's end. Neptune is still near its best viewing this month. Just past opposition last month, Neptune precedes Saturn by about a half hour. Follow Neptune across the sky all month too. Neptune is in the constellation of Pisces shining at magnitude 7.7.

Dwarf Planets

Ceres

Rises at 00:01 a.m. on the 1st and about 9:24 p.m. by month's end. Ceres can be spotted low to the south in the late evening/morning sky before sunrise. Ceres is in the constellation of Gemini shining at magnitude 8.5.

Pluto

Is stationary on the 16th. Pluto Sets at 1:22 a.m. on the 1st and about 10:17 p.m. by month's end. Pluto can be spotted to the south/southwest in the early evening. 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.

Astronomical Events

Meteor Showers

  • The Draconids - This shower is associated with periodic comet Giacobini-Zinner. The duration may extend from October 6 to 10, though the point of maximum is very sharply defined within a 4-hour interval on October 9, but the annual maximum hourly rates are not consistent. The radiant rarely produces any recognizable shower except during years especially close to the parent comet's perihelion passage. The meteors are slow and tend to be relatively faint. They are generally yellow.

  • The Orionids - The duration of this meteor shower extends from October 15 to 29, with maximum occurring on (the morning of) October 21. The maximum hourly rate is usually about 20 and the meteors are described as fast.


  • The Southern Taurids - This meteor shower is active from September 10 to November 20. Maximum occurs on the morning of October 10. Maximum hourly rate is 5 meteors per hour. The meteors are described as bright and move more slowly than typical meteors, making them prime subjects for imaging and viewing.

    Meteor Shower Radiant Report

    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.

  • Comets

  • Comet 161P/Hartley-IRAS is shining around 9th to 10th magnitude passing through the constellation of Aquarius. Get away from city lights to see this comet, glowing green from the inner coma. This comet is moving fast, 15" of arc per minute, so viewers will see it move within your field of view in just a few minutes of observation.

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

    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.
