Description
Comet 366P/Spacewatch was recently recovered as P/2018 F2 and its orbit showed that it was the observed comet P/2005 JN. So because it has been observed in the past it has been given the official designation of 366P. 366P made its close approach to Earth on April 7 when it was 131 million miles from Earth. It reaches perihelion on July 21 when it will be 212 million miles from the Sun in its 6.54 year orbit. In this image it is 132 million miles from Earth and magnitude 18.9, about as bright as it will get unless it decides to surprise us Earthlings.

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".
