Edmund Halley, William Herschel, Harlow Shapley, and Edwin Hubble were born this month.

Wolfgang Schuler discovers Tycho’s Supernova on November 6, 1572. Cornelius Gemma independently discovers Tycho’s Supernova on November 9, 1572. Tycho Brahe observes Tycho’s Supernova on November 11, 1572. Nicolas-Claude Fabri de Peiresc makes the first telescopic observations of M42 (the Orion Nebula) on November 26, 1610. Jan Munck discovers Comet C/1743 X1 (the Great Comet of 1744) on November 29, 1743. Captain James Cook observes a transit of Mercury from New Zealand on November 9, 1769. The first photograph of a meteor was taken on November 26, 1885. The minor planet/comet 2060 Chiron or 95P/Chiron was discovered by Charles Kowal on November 1, 1977.

The peaks of the Southern and Northern Taurid meteor showers take place on November 5th and November 12th respectively. These streams form part of the complex associated with Comet 2P/Encke. Moonlight compromises the peaks of these two minor meteor showers. The Leonid meteor shower occurs on the morning of November 17th. Leonid meteors are debris from the periodic comet 55P/Tempel-Tuttle. Due to their high speed (71 kilometers or 44 miles per second), the fastest of any shower, the Leonids produce more fireballs than most meteor showers. Information on these meteor showers is available at https://www.imo.net/resources/calendar/

Information on Iridium flares and passes of the ISS, the Tiangong-1, the Tiangong-1, the X-37B, the HST, and other satellites can be found at http://www.heavens-above.com/

The Moon is 12.2 days old, is 86.9% illuminated, subtends 31.8 arc minutes, and resides in Aquarius on November 1st at 0:00 UT. Large tides will take place following Full Moon on November 4th. New Moon occurs on November 18th. The Moon reaches its greatest northern declination on November 8th (+19.5 degrees) and its greatest southern declination on November 22nd (-19.6 degrees). Longitudinal libration is at a maximum of +6.7 degrees on November 13th and a minimum of -7.6 degrees on November 29th. Latitudinal libration is at a maximum of +6.5 degrees on November 5th and a minimum of -6.6 degrees on November 18th. The Moon occults Aldebaran (magnitude +0.9) from most of North America on the night of November 5th and Regulus (magnitude +1.4) from southwestern North America during the day on November 11th (see http://www.lunar-occultations.com/iota/bstar/bstar.htm and page 51 of the November 2017 issue of Sky & Telescope). The waxing gibbous Moon occults Neptune from portions of Antarctica on November 27th.

The Sun is located in Libra on November 1 at 0:00 UT. It moves into Scorpius on November 23rd and Ophiuchus on November 30th.

Brightness, apparent size, illumination, distance from the Earth in astronomical units, and location data for the planets and Pluto on November 1: Mercury (-0.4, 4.9", 93% illuminated, 1.36 a.u., Libra), Venus (magnitude -3.9, 10.4", 96% illuminated, 1.61 a.u., Virgo), Mars (magnitude +1.8, 3.9", 97% illuminated, 2.41 a.u., Virgo), Jupiter (magnitude -1.7, 30.7", 100% illuminated, 6.43 a.u., Virgo), Saturn (magnitude +0.5, 15.5", 100% illuminated, 10.73 a.u., Ophiuchus), Uranus (magnitude +5.7, 3.7", 100% illuminated, 19.03 a.u. on November 16th, Pisces), Neptune (magnitude +7.9, 2.3", 100% illuminated, 29.63 a.u. on November 16th, Aquarius), and Pluto (magnitude +14.3, 0.1", 100% illuminated, 34.02 a.u. on November 16th, Sagittarius).

During the evening, Mercury and Saturn are in the southwest, Uranus is in the east, and Neptune is in the southeast. Uranus lies in the southwest and Neptune in the west at midnight. Venus and Jupiter are located in the east and Mars in southeast in the morning sky.

Venus, Mars, and Jupiter are all located in Libra on November 1st.

Mercury is well positioned in the evening sky in November. It departs Libra and enters Scorpius on November 5th and subsequently enters Sagittarius on November 27th. The smallest planet lies 2.2 degrees north of Antares on November 12th and is at its greatest heliocentric latitude south on November 18th. Mercury is 6.8 degrees south of the Moon on November 20th and is at greatest eastern elongation on November 24th. It passes three degrees south of Saturn on November 27th.

Venus rises approximately 90 minutes before sunrise and is situated about four degrees north of Spica on November 1st. Venus lies 16 degrees from the Sun on that date. By November 30th, its elongation is only 10 degrees. The most brilliant planet lies four degrees south of a very thin waning crescent Moon on November 17th.

On November 1st, Mars rises almost three hours before the Sun. The planet’s eastward motion carries it 1.8 degrees south of the binary star Porrima or Gamma Virginis (magnitude +2.8) on November 9th and 3.3 degrees north of Spica (magnitude +1.0) on November 28th. The Martian northern hemisphere summer begins on November 30th. Mars increases in angular size from 3.9 to 4.2 arc seconds this month.

Jupiter rises some two hours before the Sun by the end of November. It shines at its minimum brightness of magnitude -1.7 and subtends just 31arc seconds this month. Jupiter lies four degrees south of the waning crescent Moon on November 16th.

Saturn sinks into evening twilight as November progresses. It lies just 15 degrees above the horizon in the southwest an hour after the Sun sets on November 1st. M8 (the Lagoon Nebula) and M20 (the Trifid nebula) are about six degrees east of Saturn in early November. The Ringed Planet departs Ophiuchus and enters Sagittarius on November 19th. It is three degrees south of the waxing crescent Moon on the evening of November 20th.

Uranus continues to retrograde through Pisces this month. The ice giant planet lies 4.1 degrees north-northwest of the Moon on November 30th. Uranus can be found 2.3 degrees west of the fourth-magnitude star Omicron Piscium on November 1st and 3.2 degrees west of that star on November 30th.

Neptune is stationary in right ascension and resumes direct (eastward) motion on November 22nd. The eighth planet is occulted by the waxing gibbous Moon from parts of Antarctica on November 27th. Neptune is positioned 0.6 degree south of the fourth-magnitude star Lambda Aquarii this month. A finder chart is posted at http://bluewaterastronomy.info/resource ... t-2017.png

Asteroid 7 Iris shines at seventh magnitude as it travels southward through Aries this month. Iris lies two degrees east of Beta Arietis (magnitude +2.7) in early November, 0.4 degree east of the excellent binary star Gamma Arietis (magnitude +3.9) on November 12th, and 0.5 degree east of 4 Arietis (magnitude +5.9) on November 29th. Asteroid 44Nysa (magnitude +9.6) is at opposition on November 3rd. Other moderately bright asteroids reaching opposition this month include 532 Herculina (magnitude +10.4) on November 2nd, 48 Doris (magnitude +10.9) on November 8th, and 42 Isis (magnitude +10.4) on November 17th.

Comet C/2016 R2 (PanSTARRS) may reach tenth magnitude in brightness as it passes northwestward through Orion during November. The rather dim Oort Cloud comet is located one degree north-northwest of the second-magnitude star Delta Orionis (Mintaka), the westernmost star in the Belt of Orion, on November 1st and one degree north of Rho Orionis (magnitude +4.5) on November 21st.
