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: I'd recommend nginx for reverse-proxying, it has reasonably non-annoying configuration and is very fast.
gollark: Reverse proxies are mostly a HTTP thing. You can probably get away with just running the other stuff on multiple ports.
gollark: You can also have that one reverse proxy server do all the HTTPS, which is mildly convenient.
gollark: So just set up the router thing to only send traffic to the reverse proxy thing, and configure that properly.
gollark: That can do other nice things, like load-balancing and serving static files fast.
