More Comet Wirtanen

Wednesday, December 19, 2018



Clouds were quickly encroaching the view when I was able to get this capture of the 8.8 magnitude Comet 46P/Wirtanen (arrow) at 9:52 pm CST, Saturday, December 15, 2018. Minutes later and then throughout most of the night the sky was cloudy. Above the comet is the Pleiades star cluster, and at lower left is the 0.84 magnitude star Aldebaran in the constellation Taurus. This image, captured from my back deck in Cedar Rapids, Iowa, is a 5 second exposure at f/5.6, ISO 8000 and 52mm focal length.


One day later and Comet Wirtanen was at its closest approach to Earth. The comet (arrow) is 53 degrees above the horizon in the southeast sky. This image was captured from Bowman Woods Park in Cedar Rapids, Iowa at 7:47 pm CST, Sunday, December 16, 2018. The image is a stack of four frames--3 sky and one ground--with each sky image a five second exposure at f/3.5, ISO 2500 and 18mm focal length. The constellation Orion can be seen just above the horizon. Air temperature was 31 degrees F.


Zoomed in version of the comet (arrow) at 7:58 pm. Four image stack. Each frame is a five second exposure at f/5.6, ISO 6400, 55mm focal length. The Pleiades star cluster is prominently seen at upper right. Nikon D7200 DSLR camera.

Comet Can't Evade Camera

Saturday, December 15, 2018


On the night of Friday, December 14, 2018, Comet 46/PWirtanen was a fuzzy 4th magnitude blob. From my light polluted vantage point in Cedar Rapids, Iowa viewing it with the naked eye would be challenging, and as it turned out I could not make it out. But more surprising was the fact that I also couldn't locate it with my pair of binoculars. Apparently it resembled too closely nearby stars. So my last chance was the camera--(and viola')--there it appeared! The image posted here was captured at 9:26 pm CST from Bowman Woods Park looking SSE. Air temperature was 25 degrees F. The comet, located just over 7 million miles from Earth, was 62 degrees above the horizon at this moment. Image is a 5-second exposure at f/4, ISO 10,000 and 70mm focal length. Nikon D7200 DSLR. The identical image shown below contains visual information about the image.

Mississippi River Skies

Thursday, November 1, 2018


Overcast skies over the Mississippi River near McGregor, Iowa did not dull the beauty of the autumn setting as these two posted captures from Point Ann attest.
