Object coordinates updated according to AT-report 65780 of Group ATLAS
Previous RA, DEC: 11:04:23.700, -49:59:17.00 (166.09875, -49.988056)
Updated RA, DEC: 11:04:23.731, -49:59:16.91 (166.098878571, -49.98803)

there is no optical counterpart down to 20.5mag, no counterpart in 2mass, galex / the outburst shows a brightening of >6mags

KKO derived astrometry vs UCAC2 frame: 11 04 23.73  -49 59 17.3 
with estimated uncertainties (at 1 standard deviation level) of 0.02 in RA, 0.1 in Decl.

This position agrees with the published coordinates within 2 standard deviations.
