Tonight we tried to adjust the telescope pointing but, we found that it is not possible to do fine adjustments in DECLINATION: we tried both, the hand paddle in the console room and the one in the dome, with the same result: the SLEW mode works well but the SET and GUIDE modes are not working. However, we can hear the DEC motor trying to move and also the TCS reports the SET, GUIDE commands but, the telescope fails to move and consequently we cannot adjust correctly the pointing of the telescope. Maybe there is a problem with the DEC clutch?
Also, It would help to check the balance (please): a couple of times, while adjusting the pointing on Antares, we observed a little 'jump', mostly in RA.

- Friday night restarted ctimac3 and also the CHIRON OPTGUI. Tested the system with some lamps and finally we left the CALIB2 script running. CHIRON seems to be working fine.
- On ctimac3 it is possible to connect to the network, fill the EON report, watch the cameras and environmental webpage; but not in ctimac4 because ctimac4 is connected via PublicWiFi.
- The safety lights on the stairs, are not working.
