LRS2-R was deployed in November 2015
An unscheduled warm up in January 2016 occurred. The unit was returned to Austin.
LRS2-R and LRS2-B deployed in February 2016.
Reliable offsetting between LRS2-B and LRS2-R achieved in April 2016
Data automatically transferred to TACC in April 2016
April 2016 one controller of LRS2-B was found to be dropping bits as was swapped May 2016.
Blind offsets using ACAM and gstar predictions achieved in May 2016
The UV chip on LRS2 was replaced in November 2016.
The LRS2-B spectrograph was cold-pumped Oct 2019, and has been extremely stable and productive.
As of Jan 2020 the LRS2 exposure time calculator is now available for PIs
In late Feb 2020 the CCD controller for LRS2-R was replaced after it became unreliable
In late Oct 2022 the CCD controller for LRS2-B was replaced after it showed similar signs of unreliability
