An Open Invitation
For amateur radio operators and scanner enthusiasts, when in the Denver metro area, please join the Colorado Astronomy Net on the Rocky Mountain Radio League's WØWYX 146.94 MHz and 449.825 MHz repeaters.
Due to hardware issues, links with the Allstar node, Echolink and the Cripple Creek repeater are down until further notice.
The net meets on Tuesday nights at 7 P.M. Mountain Time (US).
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 on the 1st Saturday of each month at our new Eagle Street Facility, The City of Centennial, 7272 South Eagle Street, Centennial, Colorado 80112-4244 at 9am.
** Check the website for current info during these COVID-19 times. **

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.
(All times are local unless otherwise noted.)
Planetary Highlights for November
Jupiter and Saturn are in conjunction and can be seen in the same field of view through a telescope. Don't miss this event on the Winter Solstice. Mars continues to dim as it moves away from Earth. Uranus is visible through binoculars in the constellation of Aries. Neptune is near 4th magnitude star HIP 114724 in the constellation of Aquarius and hopefully will be relatively easy to find with binoculars or a small telescope. Before sunrise, look for Venus in the east; however, Mercury is lost in the Sun's glare all month.
|
|
Mercury
Is in superior conjunction on the 19th. Mercury rises at 6:11 a.m. on the 1st and about 8:00 a.m. by month's end. Mercury is lost in the morning twilight glow all month. Mercury will return to the evening sky next month. Mercury moves from the constellation of Libra into Sagittarius shining at magnitude -0.8 on the 1st. |
|
Venus
Rises at 4:42 a.m. on the 1st and about 5:52 a.m. by month's end. Look for Venus in the east before sunrise. On the morning of the 12th, look for the crescent Moon suspended over the planet Venus. Venus moves from the constellation of Libra into Ophiuchus shining at magnitude -3.9 on the 15th. |
|
Earth
The Winter Solstice occurs at 5:02 a.m. EST on the 21st. |
|
Mars
Sets at 2:45 a.m. on the 1st and about 1:37 a.m. by month's end. Mars can be viewed all evening. The best time to observe Mars will be around 9-10 p.m. in the evenings when Mars is highest in the south. Mars is in the constellation of Pisces shining at magnitude -0.7 on the 15th. |
|
Jupiter
Sets at 9:28 p.m. on the 1st and about 6:26 p.m. by month's end. Look for Jupiter soon after sunset to the southwest. Jupiter and Saturn will be in conjunction on the 21st, passing within 0.1° south of Saturn. With a small telescope, Jupiter and Saturn will appear in the same field of view. Jupiter moves from the constellation of Sagittarius into Capricornus shining at magnitude -2.0. |
|
Saturn
Sets at 8:06 p.m. on the 1st and about 6:20 p.m. by month's end. Observe Saturn as is nears Jupiter for its conjunction on the 21st. Saturn moves from the constellation of Sagittarius into Capricornus shining at magnitude 0.6. |
|
Uranus
Sets at 4:26 a.m. on the 1st and around 2:21 a.m. by month's end. Uranus is visible in the evening almost night long. Look to the south-southeast soon after sunset to spot Uranus. Uranus is in the constellation of Aries shining at magnitude 5.7. |
|
Neptune
Sets at 12:19 a.m. on the 1st and about 10:15 p.m. by month's end. Neptune can be spotted to the south once the skies darken. Neptune is in the constellation of Aquarius shining at magnitude 7.9. |
|
Dwarf Planets |
|
Ceres
Sets at 10:46 p.m. on the 1st and around 9:30 p.m. by month's end. Ceres can be spotted to the southwest soon after sunset. Ceres is in the constellation of Aquarius shining at magnitude 9.1. |
|
Pluto
Sets at 7:36 p.m. on the 1st and around 5:39 p.m. by month's end. Pluto now precedes Jupiter and Saturn by a few minutes. Pluto is in the constellation of Sagittarius shining at magnitude 14.7.
As always, good luck at spotting Neptune, Ceres and Pluto, a large telescope and dark skies will be needed. |

Meteor Showers
The Geminids - This shower is active during the period December 6 to December 19. Upon reaching maximum activity during December 13 to 14, hourly rates are typically near 80. The meteors are described as rapid and yellowish, with about 4% displaying persistent trains. They possess an average magnitude of 2.4.
The Ursids - Occurring primarily between December 17 and 24, this meteor shower reaches maximum on December 22... The maximum hourly rate is usually between 10 and 15... Meteors belonging to this stream are typically faint.
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 88P/Howell is now passing through the constellation of Capricornus in the early evening. Comet Howell is shining about 9th or 10th magnitude about 15° above the southwest horizon, so look for the comet soon after local twilight as it will set fairly soon in the early evening.
For information, orbital elements and ephemerides on observable comets, visit the
Observable Comets page from the Harvard-Smithsonian Center for Astrophysics.
