November 2023 Astronomy Events

November 2023 Astronomy Events

AstroTelescopium Team |

November celestial activity begins with a Jupiter opposition on the 3rd and Asteroid 18 Melpomene opposition on the 5th. Shortly after, the Northern Taurid meteor shower peaks on the 12th. This occurs a day before the third opposition of the month with Uranus.

At 15 meteors per hour, the Leonids meteor shower peaks on the 18th. On this same day, the Pleiades star cluster is well placed in the night sky reaching its highest point.

Finally, the month wraps up with the Full Beaver Moon on the 27th and a day later the Hyades star cluster is well placed for observation.

8 Astronomical Events in November 2023:

For easy navigation, click an event listed above to go directly to that section of the article. Below, we will explore each of these events in greater detail.

 

First, a few technical terms to know:

Magnitude - Magnitude is the measure of an object's brightness. The lower the number the brighter the object. Conversely, the higher the number the fainter the object (ex. a magnitude -7.2 object is brighter than a magnitude +3.6 object). Without optical assistance, the naked eye can see a celestial object as dim as roughly magnitude +6.0.

Right Ascension - Right ascension is the celestial equivalent of geographic longitude. It is measured from the Sun's position during March Equinox at 00h00m00s (h=hours, m=minutes, s=seconds). This measurement increases towards the east until it completes a full circle at 24h00m00s.

Declination - Declination is the celestial equivalent of geographic latitude. It is measured northward or southward of the celestial equator as degrees (°), minutes(') and seconds ("). For example, the celestial equator has a declination of 0°0'0", the north celestial pole has a declination of +90°0'0" and the south celestial pole has a declination of -90°0'0".

AU (astronomical unit) - AU is a unit of length that measures the distance from the Earth to the Sun.

Angular Size - Angular size refers to a celestial object's apparent size as seen from an observer on Earth. It is measured in arcminutes(') and arcseconds(").

 

 

Astronomy events to mark on your November 2023 calendar:

 

November 3rd - Jupiter at opposition

Jupiter

On Friday, November 3rd, Jupiter will be at opposition and will reach its highest point in the sky around midnight local time.

A celestial object "at opposition" refers to its 180° position opposite to the Sun. During this alignment Jupiter will rise at around sunset, and set at around sunrise.

Jupiter will be at a distance of 3.98 AU, shining at magnitude -2.9 in the Aries constellation. It will measure 48.4 arcsec in diameter. A small aperture telescope or a pair of binoculars will help you observe our solar system's largest planet.

Jupiter at opposition

  • Magnitude: -2.9
  • Right ascension: 02h32m50s
  • Declination: 13°31'N
  • Constellation: Aries
  • Angular size: 48.4"

 

November 5th - Asteroid 18 Melpomene at opposition

Melpomene

On Sunday, November 5th, Asteroid 18 Melpomene will be at opposition and will reach its highest point in the sky around midnight local time.

A celestial object "at opposition" refers to its 180° position opposite to the Sun. During this alignment Melpomene will rise at around sunset, and set at around sunrise.

Melpomene will be at a distance of .863 AU, shining at magnitude +8.0 in the Eridanus constellation. A moderate aperture telescope or a pair of binoculars should be used to help you properly observe this planet.

Melpomene at opposition

  • Magnitude: +8.0
  • Right ascension: 03h07m40s
  • Declination: 4°05'S
  • Constellation: Eridanus

 

November 12th - Northern Taurid meteor shower peak

Taurids

The Northern Taurid meteor shower is active from October 13th to December 2nd. It reaches its peak on Sunday, November 12th. Its radiant point, the area from which the shower appears to emanate, is positioned in the Taurus constellation around right ascension 05h50m and declination 22°N.

According to the American Meteor Society, this meteor shower's ZHR will be approximately 5 meteors per hour. ZHR is an abbreviation for Zenithal Hourly Rate and is defined as the hourly rate at which a meteor shower produces with a clear, dark sky, and with the radiant at the zenith (highest point directly above the observer).

The parent body responsible for creating the Northern Taurid shower is comet 2P/Encke.

Tips for viewing meteor showers:

  • Do not direct your gaze solely at the radiant point. The closer a meteor is in proximity to its radiant point, the more difficult it is to see because of its shorter trail.
  • Position yourself in a dark, secluded location away from light pollution and bright city lights.
  • Allow for up to 30 minutes for your eyes to properly adjust to the dark environment.
  • Make sure to dress appropriately for the weather.
  • Bring a comfortable lawn chair in which you can recline or a blanket to lie back on.
  • Try to observe as wide an area of the sky as possible. The broader your view of the sky, the greater the chance of catching a glimpse of a meteor whizzing by.

 

November 13th - Uranus at opposition

Uranus

On Monday, November 13th, Uranus will be at opposition and reach its highest point in the sky around midnight local time.

A celestial object "at opposition" refers to its 180° position opposite to the Sun. During this alignment Uranus will rise at around sunset, and set at around sunrise.

Uranus will be at a distance of 18.63 AU, shining at magnitude +5.6 in the Aries constellation. It will measure 3.8 arcsec in diameter. A small aperture telescope or a pair of binoculars will help you observe the largest planet in the solar system.

Uranus at opposition

  • Magnitude: +5.6
  • Right ascension: 03h13m30s
  • Declination: 17°37'N
  • Constellation: Aries
  • Angular size: 3.8"

 

November 18th - Leonid meteor shower peak

Leonids

The Leonid meteor shower is active from November 3rd to December 2nd. It reaches its peak on Saturday, November 18th. Its radiant point, the area from which the shower appears to emanate, is positioned in the Leo constellation around right ascension 10h00m and declination 22°N.

According to the American Meteor Society, this meteor shower's ZHR will be approximately 15 meteors per hour. ZHR is an abbreviation for Zenithal Hourly Rate and is defined as the hourly rate at which a meteor shower produces with a clear, dark sky, and with the radiant at the zenith (highest point directly above the observer).

The parent body responsible for creating the Leonid shower is comet 55P/Tempel-Tuttle.

 

November 18th - The Pleiades cluster is well placed

M45

The Pleiades cluster, also known as M45, will reach its highest point in the sky at around midnight local time on Saturday, November 18th.

This open star cluster is visible to the naked eye. However, the use of a small aperture telescope or a pair of binoculars will provide the best views.

M45 is the nearest Messier object and lies approximately 444 light-years from Earth.

Pleiades cluster on 11/18

  • Magnitude: +1.3
  • Right ascension: 03h47m30s
  • Declination: 24°06'N
  • Constellation: Taurus

 

November 27th - Full Moon | Beavers Moon

Hunters Moon

On Monday, November 27th, the Moon will reach the full phase of its 29.5 day lunar cycle rising at around dusk and setting at around dawn. This astronomical event occurs each time the Moon's ecliptic longitude appears 180° away from the Sun's ecliptic longitude.

According to the Farmers' Almanac, traditionally the Full Moon that occurs during this time of year is referred to as the Beavers Moon. It is believed that the name originates from the observation of beavers taking shelter at this time.

Full Beavers Moon

  • Right ascension: 04h07m30s
  • Declination: 24°20'N
  • Constellation: Taurus
  • Angular size: 31'23"

November 28th - The Hyades cluster is well placed

Hyades cluster

On Tuesday, November 28th, the Hyades cluster will reach its highest point in the sky at around midnight local time.

Shining at magnitude +1.0, Hyades is visible with the naked eye. With a small aperture telescope or a pair of binoculars you will better observe this open star cluster.

The Hyades cluster, sometimes referred to as Caldwell 41, is located approximately 153 light-years from Earth.

Hyades cluster on 11/28

  • Magnitude: +1.0
  • Right ascension: 04h27m00s
