Close Encounter of the Jovian Kind

Saturday, May 12, 2018


Okay, 409 million miles is not exactly "close," but it was for the gas giant planet Jupiter in relation to Earth for all of the year 2018 on Thursday, May 10. Jupiter previously reached opposition--being directly opposite of the sun--on May 8. Above, I positioned myself in the Bowman Meadows housing development near Boyson Road and Alburnett Road in Marion, Iowa at 12:22 am on May 10.
The captured image looks southeast, with Jupiter positioned in the center. The planet shone at magnitude -2.51. Light pollution from the city of Marion can be clearly seen at right, enhanced by the five second exposure. Other Nikon 7200 DSLR camera settings for the picture were: f/3.5, 720 ISO, 12mm focal length. A retreating bank of clouds, which delayed the shooting of this image for about 20 minutes, can be seen at background left. Air temperature was 55 degrees F.


A zoomed-in, 300mm focal length capture of the Jovian system (upper right) at 12:05 am, May 10. Image is a 1/10-second exposure at f/5.6, 640 ISO. The moon alignment around Jupiter this night was: Callisto (just left and below), and from right of the planet: Ganymede, Io and Europa.
