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 ) has observed
the position of GRB 110719A 105s after the GRB.
No new object has been found within the Swift-XRT error box.

The field was observed until 06:29:34 UT, no new object brighter then 11.0
mag was observed. The limit on 20 coadded images is 11.5 mag.

We acknowladge great support received from Alain Maury at SPdA Observatory.
