MIDC News
Year of 2022
November 29, 2022
- 13:50 MST: The SRRL BMS Global PSP RG780 was calibrated on 05/13/2022, factor was updated in logger program at 13:49 MST today. -Afshin Andreas
- 13:41 MST: SRRL BMS Middle Sci-Tec seems to be operating properly and automatic substitution for primary sensors on that tracker has been shutoff. -Afshin Andreas
- 17:01 MST: SRRL BMS 11/22/2022 data for primary measurements on middle tracker has been reconstructed using redundant measurements on the south tracker. -Afshin Andreas
- 15:47 MST: SRRL Middle SciTec was replaced with the North SciTec (empty spare) at approx 13:50 MST today. Automatic substitution will be shutoff when there is greater confidence in full operation. -Afshin Andreas
- 09:40 MST: SRRL BMS Middle SciTec azimuth issues has been getting worse. Automatic substation has been enabled since sunrise. -Afshin Andreas
- 16:47 MST: SRRL BMS Middle Sci-Tec azimuth was off at sunrise this morning significantly, this affects the following: Diffuse SR25, Diffuse CM22 #1, Shaded CG4; Direct LI-201, Direct LI-190, Direct CHP1 #2, Direct NIP, Direct DR02, Direct RG780 and Photometer TWC. Automatic substitution for the Diffuse CM22 #1 & SR25 and Direct CHP1 #2 was enabled at certain times, however after tracker adjustment it later failed again. Data for primary measurements will be reconstructed later using redundant measurements on the south tracker. -Afshin Andreas
- 13:47 MST: The public MIDC web server has a problem for about a year, where the spawning of web applications can be painfully slow (most of the pages on MIDC are web applications). This problem does not exist on our internal MIDC server, therefore NREL employees should continue to use the internal server. It is assumed that the problem with the public MIDC web server will go away when it is migrated to a new server in the next few months. -Afshin Andreas
