This is a simple DDT imaging programme, composed by 2 OBs only.
The users want to detect transient optical emission from a shocked
region where a highly relativistic jet is interacting with the
interstellar medium. The jet, first detected by Chandra, is produced 
by the black hole candidate XTE J1550-564 and its analysis will allow 
the users to study the physics of jet/ISM interactions and the total 
power of relativistic jets. 
The emission is expected to be of the order of V~25 mag.

The first OB includes 2x300s V exposures + 2x400s R exposures, with no
telescope offsets.
The second OB included 5x240s exposures in I, with small telescope
offsets in between.
