Recently, there have been reports of a hallo or ring around the moon.
No, it’s not a hole in the ozone layer or divine intervention. It happens as moon light refracts when it passes through ice crystals and clouds in the upper atmosphere. A ring with a bright spot on it is called a moon dog.
Here are some events for March stargazers. Most are listed in the Hamilton Amateur Astronomers calendar.
Mercury can be seen in the west during evening twilight but difficult to see by mid-month. The best time to see Mercury is March 1-9. Normally it’s lost in the glare of the sun but you can see it near the western horizon about an hour after sunset.
Venus is also in the western evening sky setting mid-evening. Mars rises in the east during evening twilight and is visible all night. Jupiter is in the south western sky and sets in the northwest by mid-evening.
Saturn rises in the east after mid-evening and is easily seen throughout the night. Uranus is low in the south west during evening twilight and difficult to see by mid-month. Neptune can’t be seen at all this month as it’s lost behind the glare of the sun.
March 5 – Tonight is the best time all year to see Mars. Mars is nearest the Earth, which happens every 26 months. During the first two weeks of this month, Mars will be at its brightest for the entire year.
March 7 – The moon is below Mars
March 8 – The full moon this month is called the worm moon.
