NGC 1559 is aSeyfert galaxy, i.e. it has aquasar-like nuclei with very high surface brightnesses whose spectra reveal strong, high-ionisation emission lines, but unlike quasars, the host galaxy is clearly detectable. Although it was originally thought to be a member of theDorado Group,[3] subsequent observations have shown that it is in fact not a member of any galaxy group or cluster and does not have any nearby companions.[4][5] NGC 1559 has massive spiral arms and strongstar formation.[4] It contains a small bar which is oriented nearly east-west and spans 40″.[4] Its bar and disc are the source of very strong radio emissions.[4]
SN 1986L (Type II, mag. 13.5) was discovered by Robert Evans on 7 October 1986.[9][10]
SN 2005df (Type Ia, mag 13.8) was discovered by Robert Evans on 4 August 2005.[11][12] It got as bright as magnitude 12.3, making it the brightest supernova observed in 2005.[13]
SN 2009ib (Type II-P, mag. 14.7) was discovered by the CHASE project (CHilean Automatic Supernova sEarch) on 6 August 2009.[14][15]
