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

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.

Due to the size and composition of the debris from the periodic comet 2P/Encke, bright fireballs may be fairly common during the Southern and Northern Taurid meteor showers taking place in the first half of the month. The three-day-old crescent Moon poses no problem for viewing the peak of the Leonid meteor shower on the morning of November 17. Leonid meteors are debris from the periodic comet 55P/Tempel-Tuttle. Because of their high speed (71 kilometers or 44 miles per second), the Leonids produce a greater percentage of fireballs than most meteor showers.

The Moon is 15.7 days old and resides in Taurus on November 1 at 0:00 UT. Large tides will occur from November 13 through November 16. The smallest Full Moon of the year occurs on November 28. A penumbral lunar eclipse visible from western North America, Australia, the Pacific, and eastern Asia takes place on that date. Greatest eclipse occurs at 14:33 UT. Due to the nature of penumbral eclipses, the period of eclipse visibility is roughly 14:00 to 15:00 UT. The Moon reaches its greatest northern declination on November 2 (+21.0 degrees) and November 29 (+21.0 degrees) and its greatest southern declination on November 15 (-20.9 degrees). Longitudinal libration is at a maximum of +7.7 degrees on November 20 and a minimum of -7.5 degrees on November 8. Latitudinal libration is at a maximum of +6.8 degrees on November 7 and a minimum of -6.9 degrees on November 20. Browse http://www.lunar-occ...ota/iotandx.htm for information on lunar occultations. Visit http://saberdoesthes...7/05/saber-d... for tips on spotting extreme crescent Moons and http://www.curtrenz.com/moon06.html for Full Moon data. Times and dates for the lunar light rays predicted to occur in November are available at http://www.lunar-occ...o/rays/rays.htm

The Sun is located in Libra on November 1 at 0:00 UT. A total solar eclipse, the 45th of Saros 133, takes place on November 13 local time. The eclipse begins in the Northern Territory of Australia at 20:35 UT on November 14. Greatest eclipse occurs in the South Pacific at 22:11:48 UT. Totality lasts for 4 minutes and 2 seconds.

Brightness, apparent size, illumination, distance from the Earth in astronomical units, and location data for the planets and Pluto on November 1: Mercury (magnitude 0.1, 7.3", 51% illuminated, 0.92 a.u., Scorpius), Venus (magnitude -4.0, 13.3", 81% illuminated, 1.26 a.u., Virgo), Mars (magnitude 1.2, 4.6", 95% illuminated, 2.06 a.u., Ophiuchus), Jupiter (magnitude -2.7, 46.8", 100% illuminated, 4.21 a.u., Taurus), Saturn (magnitude 0.6, 15.4", 100% illuminated, 10.76 a.u., Virgo), Uranus (magnitude 5.8, 3.6", 100% illuminated, 19.23 a.u., Pisces), Neptune (magnitude 7.9, 2.3", 100% illuminated, 29.62 a.u., Aquarius), and Pluto (magnitude 14.1, 0.1", 100% illuminated, 32.83 a.u., Sagittarius).

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

At midmonth, Venus rises at 4:00 a.m. local time, Mars sets at 7:00 p.m. local time, Jupiter rises at 6:00 p.m. local time and transits at 1:00 a.m. local time, and Saturn rises at 5:00 a.m. local time for observers at latitude 40 degrees north.

Mercury reaches inferior conjunction on November 17. It reappears in the eastern sky at dawn by the end of the month when it rises 100 minutes before the Sun. During the last week in November, the speedy planet brightens from magnitude +1.6 to magnitude -0.3.

Venus rises approximately two minutes later each day. By month’s end, it rises 2.5 hours before the Sun. It has close encounters with the waning crescent Moon on November 11 and Spica on November 16 and a very close encounter with Saturn on November 27. Venus shines at magnitude -4.0 during the first half of the month.

During November, Mars moves eastward from Ophiuchus into Sagittarius. It passes less than a half a degree southwest of the bright globular cluster M22 (magnitude 5.1) on the evening of November 27. Mars shrinks to a minuscule 4.4 arc seconds in apparent size by month’s end.

Jupiter’s apparent diameter increases to 48.4 arc seconds and its magnitude to -2.8 this month. The gas giant’s retrograde or western motion carries the planet two degrees closer to the first-magnitude red giant star Aldebaran by the end of November. Jupiter is situated less than a degree from a gibbous Moon on the evenings of November 1 and November 28. Shadow transits by Io take place on the nights of November 7 and November 30 beginning at 10:11 p.m. EST and 10:22 p.m. EST respectively. Browse http://www.skyandtel...cts/planets/... to determine transits of the central meridian by the Great Red Spot. Data on the Galilean satellites is available at http://www.skyandtel...cts/javascri...

Saturn rises three hours before the Sun. Its rings span 35 arc seconds and their inclination angle increases to 18 degrees, the most in six years, by the end of the month. From November 23 to November 30, Saturn and a vastly brighter Venus lie within four degrees of each other. Saturn is located 0.8 degree east of Venus on the morning of November 26 and 0.7 degree north of Venus on the morning of November 27. For information on the satellites of Saturn, browse http://skytonight.co...cript/330850...

In the early part of the month, Uranus is located 1.5 degrees west-southwest of the sixth-magnitude star 44 Piscium. The separation increases to 2.1 degrees, by the end of November.

Neptune can be found 0.4 degrees south-southwest of the fifth-magnitude star 38 Aquarii. It resumes prograde (i.e., eastern) motion on November 9. Neptune’s largest moon Triton (magnitude 13.5) reaches northeastern elongation on November 4.

Finder charts for Uranus and Neptune can be found at http://media.skyandt...anus-Neptune... and page 50 of the September issue of Sky & Telescope.

The dwarf planet Pluto is not visible again until next year.

During November, asteroid 1 Ceres brightens from magnitude 8.0 to magnitude 7.3 as it travels on a northwestward course through the constellation of Gemini. The dwarf planet passes with three arc minutes of the third-magnitude star Eta Geminorum on November 4. Asteroid 4 Vesta is located in Taurus, some ten degrees west-southwest of 1 Ceres. A finder chart for the two minor planets appears on page 51 of the October issue of Sky & Telescope.

Comet C/2011 F1 (LINEAR) heads southeastward through Scorpius and Ophiuchus this month. On November 4, the tenth-magnitude comet passes just three arc minutes south of the fifth-magnitude star 16 Scorpii. It lies less than 0.5 degree north of the globular cluster M107 (magnitude 7.9) on November 15. See http://cometchasing.skyhound.com/ for additional information on comets visible this month.

Two stars with exoplanetary systems, Upsilon Andromedae (magnitude 4.1) and 51 Andromedae (magnitude 5.5), can be seen this month without optical aid.

The famous eclipsing variable star Algol (Beta Persei) is at a minimum, decreasing in magnitude from 2.1 to 3.4, on November 1, 4, 7, 10, 13, 16, 19, 21, 24, 27, and 30. Consult http://www.skyandtel...cts/variable... for the times of the eclipses. For more on Algol, see http://stars.astro.i.../sow/Algol.html and http://www.solstatio...ars2/algol3.htm
