Astronomical Events November 2019
Meteor Shower
One of the most prolific meteor showers is the Leonids. Its radiant is in the constellation Leo which is located in the eastern section of the sky at dawn as shown in Figure 2a. Unlike the previous years where it produced hundreds of meteors, astronomers and experts do not predict many meteors this year. A zenithal hourly rate (ZHR) of about 15 meteors might occur in the late hours of November 17 until dawn of the following day. The Leonids Meteor Shower is created by bits of debris left behind by the repeat passages through the inner solar system of comet 55P/Tempel-Tuttle. Unfortunately, the waning gibbous Moon will interfere the observations of fainter meteors.

Stars and Constellations
During the nights of November, the splendid W formation of stars known as the constellation of Cassiopeia, the wife of King Cepheus and the mother of Andromeda in the Greek mythology, the constellations of Draco, the Dragon, Ursa Minor, the Little Bear, including the constellations of Perseus and Camelopardalis lies in the northern horizon as shown in Figures 1 & 1a. In addition, the Milky Way runs from the constellation Cygnus, the Swan in the west, to the constellation Gemini, the Twin in the east. The large figures of the constellations of Pisces, the Fish and Cetus, the Sea Monster spread across the equatorial region of the sky.

Planets Whereabout
On November 1 at 6:00 PM, catch a glimpse of Mercury and Venus before they set, located 6.5 and 9.3 degrees above the southwestern horizon with magnitudes 0.59 and -3.84, respectively, and lies among the background stars of constellation Libra, the Scales. Venus is visible throughout the month. Mercury remains observable in the southwestern horizon until the first week, and by the third week, it can be observe before sunrise in the eastern horizon.

Mars rises in the eastern sky and can be observe before sunrise, with a magnitude of 1.8 and lies among the background stars of the constellation Virgo, the Virgin. The Red planet is observable at dawn in the eastern sky throughout the month.

Jupiter and Saturn are located in the southwest-western sky after sunset and lies among the background stars of the constellation Sagittarius, the Archer, with magnitude -1.9 and 0.6, respectively, throughout the month.

Uranus and Neptune are both visible in the night sky throughout the month, with magnitudes 5.7 and 7.9, lies among the background stars of the constellation Aries, the Ram, and Aquarius, the Water Bearer, respectively. Observing these planets require familiarity with a star map and a telescope to be able to view their features.

Figure 3 shows how to compare apparent magnitudes of celestial bodies such as planets and stars.
