The NOT Unbiased Transient Survey (NUTS; ATel #8992) collaboration reports the spectroscopic classification of the supernova Gaia16apd in the galaxy SDSS J120251.71+441527.4. The candidate was discovered by the Gaia Photometric Science survey.
The observations were performed with the 2.56 m Nordic Optical Telescope equipped with ALFOSC (range 320-960 nm; FWHM resolution 1.6 nm) on 2016-05-20.92 UT.
Name | Host galaxy | Redshift | Discovery (UT) | Discovery mag | Type | Phase | Notes
Gaia16apd | SDSS J120251.71+441527.4 | 0.102 | 2016-05-16.80 | 17.35 | SLSN-I | ~-5 d | (1)
(1) The transient matches the type Ic superluminous supernova SN 2010gx at a few days before maximum brightness. The spectrum is blue, with clear broad O II absorption lines in the blue part. At the redshift of the host galaxy, the absolute magnitude from the Gaia photometry is -21.0.
