Meteors galore on 2020's first weekend
"The Quadrantid meteor shower peaks before dawn January 4, when the Moon conveniently lies below the horizon. This image shows a sporadic meteor caught above a lake in the Sierra Nevada a couple of days after the 2014 Quadrantids. The random meteor was streaking through the constellation Cassiopeia the Queen." Sky This Week - Astronomy website

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.

(All times are local unless otherwise noted.)

Planetary Highlights for January

"As 2020 opens, Venus lights up the south-western sky starting soon after sunset. It undergoes a rare close conjunction with Neptune during January's final week, when the two worlds appear within the same fields of view. But Neptune and its outer solar system sibling, Uranus, remain relatively easy evening targets all month. Most of the other planets inhabit the pre-dawn sky. Mars rises first and climbs clear of the southeastern horizon by the time twilight begins, while Jupiter and Saturn reappear in late January." Astronomy Magazine, January 2020, P. 36.

Mercury

Is in superior conjunction on the 10th. Mercury rises at 7:06 a.m. on the 1st. After the 10th, Mercury returns to the evening sky, but is not visible until the last week of the month, low on the western horizon soon after sunset. Mercury sets around 6:32 p.m. by month's end. Mercury moves from the constellation of Sagittarius into Aquarius this month shining at magnitude -1.0 on the 31st.

Venus

Sets at 7:31 p.m. on the 1st and about 8:40 p.m. by month's end. Look for Venus soon after sunset to the southwest. On the evening of the 27th, Venus passes within 0.08° of Neptune. Both planets can be spotted in the same field of view with a modest telescope. Venus moves from the constellation of Capricornus into Aquarius shining at magnitude -4.0 on the 15th.

Earth Is at perihelion (91.4 million miles from the Sun) on the 5th.
Mars

Rises at 4:08 a.m. on the 1st and about 3:49 a.m. by month's end. Look to the southeast about an hour before sunrise to spot Mars. Mars moves from the constellation of Libra into Ophiuchus shining at magnitude 1.5.

Jupiter

Rises at 7:06 p.m. on the 1st and about 5:30 a.m. by month's end. Having passed conjunction late last month, Jupiter is not visible until the last week of January. Jupiter is in the constellation of Sagittarius shining at magnitude -1.9 on the 31st.

Saturn

Is in conjunction with the Sun on the 13th. Saturn sets at 5:34 p.m. on the 1st. Saturn rises around 6:14 a.m. by month's end. Saturn is lost in both the evening and morning twilight glow for most of the month. Saturn is barely visible during the last few days of the month just minutes before sunrise, but may be too low to spot. Saturn is in the constellation of Sagittarius shining at magnitude 0.6 on the 31st.

Uranus

Is stationary on the 11th. Uranus sets at 2:03 a.m. on the 1st and about 12:02 a.m. by month's end. By the time the Sun sets and the skies darken, Uranus is high in the south and can be seen through a good pair of binoculars. Uranus is in the constellation of Aries shining at magnitude 5.8.

Neptune

Sets at 10:07 p.m. on the 1st and about 8:09 p.m. by month's end. Look for Neptune to the southwest early in the evening. Neptune is in the constellation of Aquarius shining at magnitude 7.9.

Dwarf Planets

Ceres

Is in conjunction with the Sun on the 13th. Ceres is not visible this month as it is lost in the evening and morning twilight glow of the Sun. Ceres is in the constellation of Sagittarius shining at magnitude 9.0.

Pluto

Is in conjunction with the Sun on the 13th. Pluto s not visible this month as it is lost in the evening and morning twilight glow of the Sun. Pluto is in the constellation of Sagittarius shining at magnitude 14.4.

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

Astronomical Events

Meteor Showers

  • The Quadrantids - This shower is generally visible between December 28 and January 7, with a very sharp maximum of 45 to 200 meteors per hour occurring during January 3 and 4. The meteors tend to be bluish and possess an average magnitude of about 2.8.

    This year, meteor experts are predicting 2 meteors per minute during the short peak duration of several hours after the Moon sets around 1 a.m. local time on the 4th for North American observers.

    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 PANSTARRS (C/2017 T2) should glow around 9th magnitude this month as it passes between the constellations of Cassiopeia and Perseus. An 8-inch telescope should be able to pick out this dim object from the suburbs. The best time to observe the comet will start around mid-month. On the evenings of the 26/27 the comet passes about 1° north to the Double Cluster in Cassiopeia.

  • For information, orbital elements and ephemerides on observable comets, visit the Observable Comets page from the Harvard-Smithsonian Center for Astrophysics.

    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 Venus in the early evening sky soon after sunset.

    NASA's Juno Navigators Enable Jupiter Cyclone Discovery

    Full Article & Images

    "Jupiter's south pole has a new cyclone. The discovery of the massive Jovian tempest occurred on Nov. 3, 2019, during the most recent data-gathering flyby of Jupiter by NASA's Juno spacecraft. It was the 22nd flyby during which the solar-powered spacecraft collected science data on the gas giant, soaring only 2,175 miles (3,500 kilometers) above its cloud tops. The flyby also marked a victory for the mission team, whose innovative measures kept the solar-powered spacecraft clear of what could have been a mission-ending eclipse."

    JMARS

    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.

    Laboratory for Atmospheric and Space Physics

    "The Laboratory for Atmospheric and Space Physics (LASP) at the University of Colorado Boulder (CU) began in 1948, a decade before NASA. We are the world's only research institute to have sent instruments to all eight planets and Pluto.

    LASP combines all aspects of space exploration through our expertise in science, engineering, mission operations, and scientific data analysis. As part of CU, LASP also works to educate and train the next generation of space scientists, engineers and mission operators by integrating undergraduate and graduate students into working teams. Our students take their unique experiences with them into government or industry, or remain in academia to continue the cycle of exploration.

    LASP is an affiliate of CU-Boulder AeroSpace Ventures, a collaboration among aerospace-related departments, institutes, centers, government labs, and industry partners."

    LASP/MAVEN - December 12, 2019
    Brilliant Martian aurora sheds light on Mars' changing climate

    Full Article & Images

    "A type of Martian aurora first identified by NASA's MAVEN spacecraft in 2016 is actually the most common form of aurora occurring on the Red Planet, according to new results from the mission. The aurora is known as a proton aurora and can help scientists track water loss from Mars' atmosphere."

    Mars Odyssey Orbiter - August 23, 2019
    What's Mars Solar Conjunction, and Why Does It Matter?

    Full Article and Images

    "The daily chatter between antennas here on Earth and those on NASA spacecraft at Mars is about to get much quieter for a few weeks.

    That's because Mars and Earth will be on opposite sides of the Sun, a period known as Mars solar conjunction. The Sun expels hot, ionized gas from its corona, which extends far into space. During solar conjunction, this gas can interfere with radio signals when engineers try to communicate with spacecraft at Mars, corrupting commands and resulting in unexpected behavior from our deep space explorers."

    Journey to Mars - InSight - Revealing the Heart of Mars - November 6, 2019
    Common Questions about InSight's 'Mole'

    Full Article and Images

    "Q: Why can't you pick up the 'mole' and move it to another spot?

    A: The mole is part of the instrument called the Heat Flow and Physical Properties Package, or HP3, and was designed to be housed within HP3's support structure. The support structure of HP3 was outfitted with a knob, or "grapple point," that the robotic arm can grasp in order to move it from the lander's deck onto the Martian surface. Designed to be housed within the support structure, the mole itself has no grapple point and was not intended to be grasped or moved.

    Even if the mole could be moved, relocating it would be an unlikely solution. The team is confident that the probe has been unable to dig because the soil doesn't provide enough friction. Anywhere you move the mole near the lander would likely pose the same problem. The strategy of "pinning" -- pressing the robotic arm's scoop against the side of the mole -- compensates for that lack of friction and helped the mole progress downward in early October."
