The second half of the night the tracking of the telescope presented serious problems, it did not work at the correct rate. I noted this problem observing L533-002A and L533B, it was not possible to maintain the star in the fiber with the auto guider, I had to observe these stars using manual guiding. I noted that the problem increased when I pointed to LEP1422-7023, I could not maintain this star in the fiber even using manual guiding, the star was moving in RA in the guider very fast. Several stars were pointed in order to check the track rate of the telescope at different positions, I observed that the track rate change, depending on the position of the telescope, so it seems to be a mechanic problem.
TELOPS: Please check the telescope as soon as possible!

I recommend do not consider the observations of L533-002A and L533-002B because using manual guiding for a long time, the quality of the spectra are not the best.
