Super \u201cFlower\u201d Moon<\/a><\/p>\n

I put the new Canon EF 100-400mm lens<\/a> on my Canon EOS REbel SL1 camera last evening to attempt to photograph the full moon at perigee. So called a “super” moon, it only appears slightly larger to the naked eye, but is around thirty thousand miles closer than when at apogee.<\/p>\n

From EarthSky<\/a>:<\/p>\n

This year\u2019s farthest apogee comes on March 24, 2020 (252,707 miles or 406,692 km), and the closest perigee occurs some 2 weeks later, on April 7 (221,772 miles or 356,907 km). That\u2019s a difference of about 30,000 miles (50,000 km). Meanwhile, the moon\u2019s mean distance (semi-major axis) from Earth is 238,855 miles (384,400 km).<\/p><\/blockquote>\n

There is good Lunar information at the above link with a nice photo comparison of the difference in apparent size from perigee to apogee. There is also a graphical illustration showing the lunar elliptical orbit compared to a circular orbit about the earth.<\/p>\n

I took the above image at 8:28 PM AZ time last evening from the courtyard in front of our little house. The camera was set to Tv (shutter priority) with an exposure of i\/4000 sec. The focal length was set to 400mm and the ISO was set to 6400. The lens aperture at this setting is F5.6. I also took this photo of the moon last Tuesday while it was in its waxing gibbous phase.<\/p>\n

The moniker “Flower Moon” is based on the fact<\/a> that there are flowers in bloom at this time of year. We certainly have a lot of them opening almost daily in April\/May.<\/p>\n

Update: I found out that it was also possible to resolve the planet Venus as a crescent using the new lens.<\/p>\n
