Supernova Suspect proves to be an Asteroid!
A clear moonless night on 1999
April 18th enabled me to image a few galaxies in the Virgo Cluster.
Starting my observations at 6 Com I first viewed M99 and M98
and then swept to the east and came across a fine pair of galaxies
just a few arc minutes apart. These were NGC 4298 a mottled spiral
galaxy and its companion NGC 4302 which is a slender edge on galaxy with
a dark dust lane. They both formed such a striking pair and as I
hadn't imaged them before I took a few deep exposures. After processing
I compared the image with that on the Realsky CD-ROM (the digitised Palomar
Sky Survey) and was intrigued to find what looked like a "new star" had
appeared on my image. Was this a supernova? Alas no, Guy Hurst
editor of the Astronomer
identified the culprit as asteroid 8159 which happened to be gliding
through the field of view as the image was taken.
