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.

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.

"From our point of view, the Moon and the Pleiades (M45) often "miss" each other in the sky, as shown here. But we are now in a sequence of monthly Pleiades occultations, with one visible from the U.S. this month." Astronomy Magazine, February 2025, p. 28. - Alan Dyer

Calendar of All Astronomical Events 2025

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.

(Times are Mountain Daylight Time (MDT/MST) unless otherwise noted. Times will vary slightly depending on your location.)

Planetary Highlights for January

"We're quickly losing sight of Saturn, but Venus, Jupiter, and Mars dominate the sky. Uranus and Neptune are easy binocular objects. Mars is still at its best, having reached opposition last month. Jupiter has many satellite transits visible in small telescopes. And early in the month, the Moon passes in front of the Pleiades, visible from the western U.S." Astronomy Magazine, February 2025, p. 28.

Mercury

Is in superior conjunction on the 9th. Mercury rises at 7:02 a.m. on the 1st. After conjunction, Mercury returns to the evening sky. Mercury sets about 7:13 p.m. by month's end. Mercury is visible about 30 minutes after sunset just above the western horizon during the last week of February. Mercury moves from the constellation of Capricornus into Pisces shining at magnitude -1.1 on the 28th.

Venus

Is at greatest brilliancy (magnitude -4.9) on the 14th. Venus is stationary on the 27th. Venus sets about 9:07 p.m. on the 1st and about 8:27 p.m. by month's end. Look for Venus to the west about 30 minutes after sunset. Venus is in the constellation of Pisces shining at magnitude -4.9 on the 15th.

Earth

N/A.

Mars

Is stationary on the 24th. Mars rises at 3:01 p.m. on the 1st and about 12:59 p.m. by month's end. Look for Mars to the southeast in the evening. Follow Mars across the sky almost all night long. Mars is the constellation of Gemini shining at magnitude -0.7.

Jupiter

Is stationary on the 4th. Jupiter sets at 3:12 a.m. on the 1st and about 1:27 a.m. by month's end. Jupiter is easy to spot to the south in the evening sky. Follow Jupiter across the sky for the rest of the evening and into the early morning hours. Jupiter is in the constellation of Taurus shining at magnitude -2.4.

Saturn

Sets at 8:07 p.m. on the 1st and about 6:34 p.m. by month's end. By the time the Sun sets, Saturn is low to the west. Saturn is in the constellation of Aquarius shining at magnitude 1.1.

Uranus

Sets at 1:44 a.m. on the 1st and about 11:52 p.m. by month's end. Look for Uranus to the south soon after sunset. Uranus moves from the constellation Aries into Taurus shining at magnitude 5.7.

Neptune

Sets at 9:01 p.m. on the 1st and about 7:15 p.m. by the month's end. Look for Neptune to the west following Saturn by less than an hour all month. Neptune is in the constellation of Pisces shining at magnitude 7.8.

Dwarf Planets

Ceres

Is in conjunction with the Sun on the 14th. Ceres sets at 5:43 p.m. on the 1st. After conjunction, Ceres returns to the morning sky, rising about 6:48 a.m. by month's end. Ceres is lost in the evening and morning twilight glow all month and is not visible. Ceres moves from the constellation of Capricornus into Aquarius shining at magnitude 9.0.

Pluto

Rises at 6:50 a.m. on the 1st and about 5:03 a.m. by month's end. Pluto is lost in the morning and twilight glow for most month. 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

  • "FEBRUARY HAS NO major meteor showers. Sporadic meteors can be seen at any time, so it's worth keeping watch for the occasional bright streak while observing the wonders of the night sky.

    As we approach the vernal equinox, the zodiacal light makes an evening appearance on moonless nights. The most favorable time is the second half of the month, when the Moon is in the morning sky. Pick a dark location with a clear view west. Right after dusk, as the sky darkens, watch for a cone-shaped glow, similar to the Milky Way. Whereas twilight is a low, diminishing glow to the west, the zodiacal light is a steeply angled cone aligned with the ecliptic in the east, extending up through Taurus. It lasts over an hour and is caused by sunlight reflecting off billions of meteoritic particles." Astronomy Magazine, February 2025, p. 29.

    Meteor Shower Radiant Report

    For more information about Meteor Showers, visit Gary Kronk's Meteor Showers Online web page.

    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 29P/Schwassmann-Wachmann 1 may still have an outburst in brightness from around magnitude 15 to 10.5 this month, but will be a challenge for most observers. The comet is passing just south of Regulus in the constellation of Leo.

  • Comet C/2024 G3 (ATLAS) is visible in the southern hemisphere in the constellation of Piscis Austrinus, shining around magnitude 4.9, making it a just visible to the naked eye observer under dark sky conditions.

    For more information about Comets, visit Gary Kronk's Cometography.com webpage.

  • Eclipses

    Solar Eclipses

  • No solar eclipse activity this month.

    Lunar Eclipses

  • No lunar eclipse activity this month.

  • Observational Opportunities

  • Look for Saturn, Neptune, Venus, Uranus and Jupiter and Mars in the evening from the west to south.
  • Look for Mercury in the early evening to the west late in the month.

  • Asteroids

    (From west to east)
    • Eunomia is in the constellation of Taurus.
    • Vesta is in the constellation of Virgo.

    • Information about the Minor Planets can be found at the Minor Planet Observer website.
    Ocultations

    IOTA Logo

  • Information on various occultations can be found by clicking the IOTA logo.

  • The Moon occults the Pleiades (M45) (Electra) on the 5th/6th. The occultation is observable from the western third of the U.S. See the other predictions/paths for several other stars in the Pleiades: Maia, Alcyone, Atlas.

    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.
