Comet 37P/Forbes was magnitude 14.9 and 145 million miles from Earth in this image. It has a tail to the upper right of the coma in this image. The comet is low in the southeast during morning twilight. 37P will be at perihelion on May 4 on its 6.43 year orbit when it will be 149 million miles from the Sun. 37P may reach magnitude 13.5 this summer and will pass 90 million miles from the Earth August 18.

About Mike Olason

I started imaging comets in 1994 with an ST-5 CCD Camera and an 11" SC Telescope. Since then the CCD cameras have changed (ST-7, ST-402ME and STF-8300M), but I am still using the 11" SC Telescope. Naturally I have used a lot of smaller telescopes to obtain larger fields of view. I live south of Denver at an elevation of 6150 feet which allows me to image comets down to almost magnitude 21 on a perfect night. Unfortunately ChemTrails have turned Denver cloudy and dry. I use the camera software CCDOps to process my images. All I do to each image is dark subtraction and flat field, stack images as required to show faint comets, contrast/bright adjust the final image and maybe use a median filter to reduce the image noise. The result is an image that reflects reality and will never win any picture of the day award. If you would like to use my images for a project or ask a question send me an email to "moicylander@centurylink.net".
