ENR CTIO 1.5-m 2018-04-24

At the beginning of the night, while observing the first target (HD51354) , the T.C.S. was quite slow and it lost connection with CHIRON, the same problem was reported on  2018-04-21 and 2018-04-23. After of the first report (2018-04-21) the computer of T.C.S. and Heurikon were re-started. To try to solve the problem we decided restart the T.C.S.

With the help of Humberto Orrego the T.C.S. was re-started. However, at first instance, the T.C.S. could not load the drivers, so Humberto revised the parameters of the electronic devices. After of making an adjustment of the Voltage of the source to 5V and checking several parameters, it was possible to re-start the T.C.S.  After of making a new pointing we started back the observations at 01:20 UT.

At 02:15 UT CHIRON lost connection with T.C.S. again, even more, T.C.S. got stuck and it was not possible to move the telescope. Hernan Tirado, Humberto Orrego and Rodrigo Hernandez helped to solve the problem. Humberto checked again the electronic devices, then we re-started the T.C.S. and made a new pointing. Observations started back at 03:10 UT. The rest of the night CHIRON lost connection with the T.C.S. a couple of times, it was recovered quickly.

Due to technical problems it was not possible to observe the targets: HD43544, HIP046843, HIP040724, HIP085026, A191547_2 and PG2148+095.
