NGC 1819is alenticular galaxyin theconstellationofOrion.^[4]It was discovered on December 26, 1885, by American astronomerLewis A. Swift.^[7]This galaxy is located at a distance of 197.4 millionlight-years(60.53Mpc) from theMilky Way,^[3]and is receding with a heliocentricradial velocityof4,483 km/s.^[2]

Themorphological classificationof NGC 1819 is SB0 in the De Vaucouleurs system,^[5]indicating this is a lenticular galaxy with a barred spiral organization. It is a gas-rich galaxy^[8]with a circumnuclear ring structure that is undergoing intensestar formation.^[9]

Type Ia supernova^[5]SN 2005elwas discovered in NGC 1819 on September 19, 2005. It was positioned39.0″east and22.6″south of the nucleus.^[10]
