| 4211 | 06:09-06:15 | 00:06 | Tip tilt not able to keep up with slew to target. Got the birdies again. Shut down tcs gui and servers and restarted. Perhaps this is due to the large offsets we made in phi during our last test. These were never reset. | |
| 4212 | 07:40-07:40 | 00:00 | We were doing a combination pointing and drift test leaving the telescope azimuth the same. We sent the telescope to a target at Ra:0.8246944 Dec:35.9154694 staying at the azimuth we were currently at (293.7347). The telescope said that it was on trajectory but did not seem to be settling into a certain ra and dec. This meaning that while watching the telescope on trajectory the Ra was changing by about -0.00010 hours every few seconds. The Dec was changing by about +.0180 degrees every few seconds. These changes were occurring in declination and right ascension at the same time as if the tracker was doing some sort of correction. The structure azimuth also seemed to change even though the structure never picked up. It went from 293.7374 to 290.13 which was the optimal azimuth for the target. Tried a similar test later on in the night and could not reproduce this problem. | |

| TO Comments | SWAG set at 16C, the temperature outside at 6pm local time was 12.6C. Flushed the dome for awhile to even out temps. Moved the tracker to ITF X=0 Y=0 Z=0 rho=0 theta=0 and phi=0 (current values were reading X=-0.388, Y=0.091, Z= 0.00, rho=-0.01, theta=0.00, phi=0.00). The corresponding RTF values are: X=-10.798, Y=22.949, Z=2.101, rho=-0.01, theta=-0.19, and phi=0.01. |
