The InSb crew worked primariyl from the dome. Mounted Grim at 22:45. Dust count in eclosure went over the fan limit at abou 00:15. Turned on the pressurization fans. Switched back to InSb at 03:00. Both Helium dewars virtually empty after last fill. Someone planned this one just right. Turned press fans back off at 04:15. Closde at 05:50.
