No problems to report. Did not begin ventilating because of clouds and nearby virga. Night: ----- 02:30Z - Began ventilation. Doors and louvers opened, fans on. 02:55Z - Enclosure off. Cartridge 4, plate 2598, chunk153, Legacy. Needed an fk5 to acquire the field. 03:41Z - Pre-Calib. 03:47Z - 15-minute exposure. 04:05Z - 15-minute exposure. 04:23Z - 15-minute exposure. Seeing: 1.2" - 1.4". SoS recommended post-calibs, but we already began the next plate. Finished this plate. Cartridge 5, plate 2665, chunk153, Legacy. Guide stars found on gotoField. 04:55Z - Pre-Calib. 05:01Z - 15-minute exposure. 05:18Z - 15-minute exposure. 05:36Z - 15-minute exposure. Seeing: 1.3" - 1.6". SoS recommended post-calibs, but we already began the next plate. Finished this plate. Cartridge 6, plate 2642, chunk153, Legacy. Guide stars found on gotoField. 06:02Z - Pre-Calib. 06:08Z - 15-minute exposure. 06:26Z - 15-minute exposure. 06:44Z - 15-minute exposure. Seeing: 1.3" - 1.6". SoS gave no warnings. Finished this plate. Cartridge 3, plate 2746, chunk165, Legacy. Guide stars found on gotoField. 07:10Z - Pre-Calib. 07:16Z - 15-minute exposure. 07:33Z - 20-minute exposure. 07:56Z - 20-minute exposure. Seeing: 1.2" - 1.3".

(by accident) 08:41Z - 15-minute exposure. 08:59Z - 20-minute exposure. 09:22Z - 20-minute exposure. Seeing: 1.1" - 1.4". SoS gave no warnings. Finished this plate. Cartridge 7, plate 2192, seguefaint118. Guide stars on gotoField. 09:56Z - Pre-Calib. 10:03Z - 20-minute exposure. 10:26Z - 15-minute exposure. 10:44Z - Post-Calib. Seeing: 1.2". SoS warned of a whopping fiber (#241). Finished this plate when combined with last night's data. 11:00Z - Enclosure on, doors and louvers closed, fans off. endNight rejoiced. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 6816 00:22Z 00:40Z 100 O -55.81 -51.34 44 ignore ---=== IMAGING RUN DETAILS ===--- ---=== SKIPPY RESULTS ===--- Run Frame nFrames stars muErr muRms nuErr nuRms rot az el --------------------------------------------------------------------------- ---=== LTMATCH RESULTS ===--- Run Field nFields alt az nGood rowMean rowSig colMean colSig rot ----------------------------------------------------------------------- ---=== SPECTROSCOPY DATA SUMMARY ===--- Summary Checked (y/n): yes QA Procedures Done (y/n): yes; bias (44810), flat (44814), arc (44815), arc (44820), arc (44825), science/plate 2598 (44818), science/plate 2665 (44821), science/plate 2642 (44826), science/plate 2746 (44831), science/plate 2166 (44839), science/plate 2192 (44843). NOTE: apoplotarc for ARC-00044815 (Cartridge 4, plate 2598 mounted) in camname='r2' yields a line of central wavelength 8047 Ang. that has peak flux of 7.2E4 electrons. This line is not present when apoplotarc is run for 'r1'. Similarly, there is a line of central wavelength 4889 Ang. with peak flux 1.4E5 electrons for camname='b1' that does not show up in 'b2'. These new species are relatively strong. apoplotarc for ARC-00044820 (Cartridge 5, plate 2665 mounted) does not exhibit the line behavior described above. That is, the lines in 'r2' were seen in 'r1' with very similar fluxes and no noticeable species appeared in one which did not appear in the other. The same goes for those seen in 'b1' and 'b2', however in 'b1' a line at 4685 Ang. and flux 2.5E4 electrons appears which is not seen in 'b2', but this discrepancy is not as noticeable because the flux of this new line is relatively low. apoplotarc for ARC-00044825 (Cartridge 6, plate 2642 mounted) does not exhibit any of the behavior described above. No new lines are seen in 'r1' that aren't in 'r2' and vice versa. The same goes for 'b1' and 'b2'.
