Low-mass star or brown dwarf

As noticed by Jörg Schümann: The position is consistent with a high proper motion object, the L3-dwarf 2MASS J02511490-0352459. The R-band shows 18.85 mag and 16.51 in the I-band in SIMBAD from Liebert & Gizis 2006. The above transient discovery shows 18.2 with CLEAR filter.

The discovery report describes the last non-detection at 2015-09-20 and with a total proper motion of about 2 arcsec/year (Jameson et al. 2008), it would travel about 8 arcsec in these 4 years. Maybe enough to confuse any automatic detection of a transient.
