Notes.a Phases are relative to the r-band maximum light: MJD= 58211.1.
* ATLAS (Asteroid Terrestrial-impact Last Alert System; Heinze et al. 2018; Tonry et al. 2018; Smith et al. 2020) observations in cyan- and orange-band magnitudes are reported in the sloan g and r columns respectively.
1 Unfiltered KAIT data reported to the sloan r magnitudes (AB system). Data from the Transient Name Server (TNS; https://wis-tns.weizmann.ac.il/object/2018aes).
2 The i-band magnitude is the weighted mean value obtained from the Pan-STARRS Survey for Transients (see website: https://star.pst.qub.ac.uk/sne/ps13pi/psdb/lightcurve/1134817771035644300/).
Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.
Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.
