NATIONAL ASTRONOMY DAY
Astronomy events to look out for over the coming months
• March 20 - March Equinox. The March equinox occurs at 16:57 UTC. The Sun will shine directly on the equator and there will be nearly equal amounts of day and night throughout the world. This is also the first day of spring (vernal equinox) in the Northern Hemisphere and the first day of fall (autumnal equinox) in the Southern Hemisphere.
• April 8 - Mars at Opposition. The red planet will be at its closest approach to Earth and its face will be fully illuminated by the Sun. This is the best time to view and photograph Mars. A medium-sized telescope will allow you to see some of the dark details on the planet’s orange surface. You may even be able to see one or both of the bright white polar ice caps.
• April 22, 23 - Lyrids Meteor Shower. The Lyrids is an average shower, usually producing about 20 meteors per hour at its peak. It is produced by dust particles left behind by comet C/1861 G1 Thatcher, which was discovered in 1861. The shower runs annually from April 16-25. It peaks this year on the night of the 22nd and morning of the 23rd. These meteors can sometimes produce bright dust trails that last for several seconds. The second quarter moon will be a slight problem this year, blocking the less bright meteors from view. Best viewing will be from a dark location after midnight. Meteors will radiate from the constellation Lyra, but can appear anywhere in the sky.
• April 29 - Annular Solar Eclipse. An annular solar eclipse occurs when the Moon is too far away from the Earth to completely cover the Sun. This results in a ring of light around the darkened Moon. The Sun’s corona is not visible during an annular eclipse. The path of the eclipse will begin off the coast of South Africa and move across Antarctica and into the east coast of Australia.
• May 5, 6 - Eta Aquarids Meteor Shower. The Eta Aquarids is an above average shower, capable of producing up to 60 meteors per hour at its peak. Most of the activity is seen in the Southern Hemisphere. In the Northern Hemisphere, the rate can reach about 30 meteors per hour. It is produced by dust particles left behind by comet Halley, which has known and observed since ancient times. The shower runs annually from April 19 to May 28. It peaks this year on the night of May 5 and the morning of the May 6. The first quarter moon will set just after midnight leaving fairly dark skies for what should be a good show. Best viewing will be from a dark location after midnight. Meteors will radiate from the constellation Aquarius, but can appear anywhere in the sky.
• May 10 - Astronomy Day Part 1. Astronomy Day is an annual event intended to provide a means of interaction between the general public and various astronomy enthusiasts, groups and professionals. The theme of Astronomy Day is “Bringing Astronomy to the People,” and on this day astronomy and stargazing clubs and other organizations around the world will plan special events. You can find out about special local events by contacting your local astronomy club or planetarium.
• May 10 - Saturn at Opposition. The ringed planet will be at its closest approach to Earth and its face will be fully illuminated by the Sun. This is the best time to view and photograph Saturn and its moons. A medium-sized or larger telescope will allow you to see Saturn’s rings and a few of its brightest moons.
• May 24 - Possible Meteor Storm. In the early morning hours of Saturday, May 24, the Earth will pass through the debris field left behind by a small comet known as P/209 LINEAR. Astronomers are predicting that this interaction may result in a brief but intense burst of meteor activity that could range from dozens to hundreds of meteors per hour. Nothing is certain, but many mathematical models are predicting that this could be the most intense meteor shower in more than a decade.
