North is to the bottom.
NGC 2403, discovered by William Herschel in 1788, is an intermediate spiral galaxy in the constellation Camelopardalis. At a distance of eight to ten million light-years, the galaxy is an outlying member of the M81 group. Scattered thought the galaxy are many HII regions. Nearly 1000 are identified in the NED database. At least six of these hydrogen clouds are considered giant HII regions, possibly fifty times larger than the Orion cloud in our galaxy.
