A. Maury ( San Pedro de Atacama Celestial Explorations ) The wide field "Pi of the Sky South" apparatus, installed in the private observatory of Alain Maury in San Pedro de Atacama ( http://grb.fuw.edu.pl/pi/index.html#spda_site.htm ), collected images of field of SGR 1E 1841-045, just before and 68 seconds after the Swift-BAT trigger ( 456505 ). No new source brighter than 11.5 mag has been identified on 10s exposures: t_start - t0 start (UT) end (UT) 3-sigma limit -10 08:38:28 08:38:38 11.5 +68 08:39:46 08:39:56 11.5 where limit is based on nearby reference stars magnitudo in V filter.
