On 22 January 2014, S. J. Fossey discovered a supernova, designated SN 2014J, in the Cigar Galaxy, Messier 82. It’s turned out to be the brightest of its type visible in the Northern Hemisphere in living memory. M82 is in Ursa Major, nice and high in the night sky for those of is in the Great White North! It is not visible to the unaided eye, clocking in at about Magnitude 11.5, but that’s well within the capability of a home telescope on a dark night to spot, and especially with a short exposure with a digital camera on a 4″ or 5″ telescope.
I wanted to see if I could take an image of the supernova from my livingroom couch, and so used a simple web form to request an image be taken by the MicroObservatory Network in Arizona. Anyone can use this free educational system, using the on-line forms at: http://mo-www.harvard.edu/MicroObservatory/
The simple icon-driven menu asks for subject, field of view, and exposure time. All the rest is automated. I sent the request in on 25 January, and on the afternoon of the 26th I received an email message from the system indicating that an image was ready. Here’s the result. The supernova is the bright star to the right of centre of the irregular galaxy.
The fact that the galaxy is so far over to the right side of the frame is the result of errors in the on-line system. It amounts to perhaps a 10th of a degree or less, but that’s enough to put things way off of centre. Given that this is a free, public-access system, you can’t complain too much! I wish I had had access to a system like this as a child – this and other robotic telescope systems now available to the public would make for amazing science fair projects! I have an article in a forthcoming issue of the Hamilton Amateur Astronomer’s newsletter The Event Horizon on robotic observatories, which I find a very nice way of avoiding the cold outside conditions of astronomy in Canada in the winter. Yes, I’m a wimp, but I’m a warm wimp.
