In this GIF Comet 64P/Swift-Gehrels is magnitude 18.5 and 121 million miles from Earth. Comet 64p will make its close approach to Earth October 28 when it will be 41 million miles from Earth at a predicted magnitude of 10. 64P will reach perihelion in its 9.41 year orbit November 3 when it will be 129 million miles from the Sun. Comet 64P will only be 4.5 degrees from the center of the background Andromeda Galaxy M31 during the week of it's close appraoch to Earth.

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 "".
