GNIRS camera turret locked at Short Blue

April 22nd, 2024

In early April 2024, the GNIRS camera turret experienced a mechanical issue​, ​likely due to the dragging of a bearing that helps drive the movement of the turret. It has been assessed that GNIRS could no longer reliably shift between its long and short cameras​. ​A soft lock on the camera turret ​has been put in place, which fix​es the​ location of the turret to the short blue camera.

GNIRS detector degraded performance

January 31st, 2024

GNIRS recently began showing an issue that affects every 8th column on the top right quadrant of the detector, an issue that impacts all GNIRS modes. This issue first appeared on the 25th of October, 2022. Investigations to mitigate or fix the issue are currently ongoing. For the time being, PIs are advised to consider all pixels associated with these columns as bad pixels and not to use them for science and/or calibrations.
