MAROON-X experienced two shifts in the echelle image in 24A: the first due to an earthquake on Feb 9, 2024, and the second due to a loss of observatory power on June 13, 2024. This has impacted two key steps in the reduction process. As a result, the radial velocities from 24A based on the existing reduction are currently uncertain to ~20 m/s. All data from 24B so far seem to be within specifications. The instrument team in Chicago has been adjusting the reduction procedure with the aim of resolving this issue and restoring the nominal data quality. Once the new data reduction procedure is in place and tested, the instrument team will reanalyze all affected datasets and deliver the final data products to the PIs.
