Although all eyes are focusing on comet ISON there was another very important comet fact.
On This day
November 19th 1783
This is the 250th anniversary of the first comet to be named after the Englishman who discovered it.
Edward Piggot discovered a comet from his observatory in York. It was not very bright and could only be seen with a small telescope.
Edward Piggot worked with John Goodricke the deaf astronomer, for a brief moment in time during the 1780s they made York one of the astronomical centres of the world. They discovered several stars that change in brightness and today astronomers call them variable stars.
