894561999-03-22 06:55:2220.711ABMagr-SloanSloan_SDSS-SpecThe r-band Apparent magnitude was calculated by Richard Nowell using APT and reference star: SDSS J115119.16-005858.0 http://skyserver.sdss.org/dr14/en/tools/explore/Summary.aspx?id=1237648720156033217. The r-band Absolute magnitude of -17.10 was also calculated (using an SDSS estimated redshift).

In the SDSS database, the transient is categorised as a galaxy. However, in later surveys DECaLS, Pan-STARRS and especially HST DR2, no galaxy is visible.
