NGC 694

NGC 694 is a spiral galaxy approximately 136 million light-years away from Earth in the constellation of Aries.[3] It was discovered by German astronomer Heinrich Louis d'Arrest on December 2, 1861 with the 11-inch refractor at Copenhagen.[4]

Supernova SN 2014bu

Supernova SN 2014bu was discovered in NGC 694 on June 17, 2014 by Berto Monard. [7]

SN 2014bu had magnitude about 15.5 and was located at (coordinates: RA 01h50m58.4s, DEC +22d00m00s, J2000.0).[1] It was classified as type II-P supernova. [7]

gollark: It can generate ~100MHz square waves and you can connect up an antenna, which is *basically* what a radio transmitter would do but stupider and worse.
gollark: Yes, a clock or something.
gollark: A quirk of the raspberry pi means it can transmit FM radio with horrible interference because it can only broadcast square waves or something, because of happening to have a somewhat adjustable ~100MHz clock exposed on external pins or something.
gollark: Technically I *could* transmit FM radio. Also technically, I can't transmit it at any significant power and doing so would be illegal.
gollark: idea: replace osmarks internet radio™ with a constant 440Hz buzzing noise.
