What’s in the Sky this Month

November

  • 1st First Full Moon in the month.
  • 1st Mars is now moving away from Earth but is still a good object in the telescope. At Mag. -1.2 it is very bright in the early evening sky at Dist. 95,232,771km. Tilt of North pole towards Earth is -24.2244 degrees.

  • 1st Jupiter followed by Saturn are both evening objects during November. They are both moving away from Earth, Jupiter at mag. -2.2, dist. 798,503.513km, tilt of North Pole towards Earth is -1.1761 degrees.  Saturn at mag. 0.6 Dist. 1,521,711,351km. Tilt of Saturn’s North pole towards Earth is 22.5572 degrees.
  • 1st Venus is a morning object rising at 04:54hr AEDT, mag. -4.0, Dist. 190,299,434km. 81.44% illuminated.
  • 1st Mercury is a morning object rising at 05:48hr AEDT just before the Sun. Mag. 1.5, dist. 112,345,702km. Tilt of North Pole towards earth is 1.5058 degrees.
  • 14th Lunar Perigee 22:45hr AEDT, Dist. 357,841.6km.
  • 18th Leonids Meteor shower peak predawn.

Leonids (LEO)Active: November 6—30; Maximum: November 18,  Pre-dawn  ZHR ~ 10; V = 71 km/s.

The last perihelion passage of the Leonid’s parent comet, 55P/Temple-Tuttle, in 1998 is almost two decades ago now. With the knowledge of the dust ejection and trail evolution, variable activity has been modelled and observed in several years. The Leonids occur during a waxing young moon and so the shower will be good viewing this year.  Credit:IMO. Radiant lower middle of image.

  • 27th Monocerotids Meteor Shower Peak in the evening.

Monocerotids (019 MON) Active: November 27–December 20; Maximum: December 9 ; ZHR = 3; V∞ = 42 km/s.
This minor shower’s details need further improvement by observational data. In most years,
visual data give a maximum ZHR = 3, while the general ZHR level is about 2.

December’s new Moon period creates perfect conditions for either potential maximum timing, as the radiant area is available virtually all night for much of the globe. Credit IMO.  Radiant of shower below Betelgeuse.

 

  • 27th Luna at Apogee 11:28hr AEDT 405,892.5 km.
  • 30th Blue Moon, second Full Moon in the Month and Penumbral Eclipse of the Moon.

Penumbra entered 18:31AEDT (below horizon in Ballarat), Penumbra exit 22:55AEDT. Moon rise Ballarat  20:28AEDT.
