  3. NAC spectroscopy • First-light spectra taken 1083-4666nm • Four guest observing runs: A. Clark, D. Deming (2231nm), J. LoPresto (1600nm), C. Walker (1565nm) User Committee

  4. NAC: X1.8 Flare 1083nm User Committee

  5. NAC: X1.8 Flare 1083nm User Committee

  6. NAC: X1.8 Flare 1083nm User Committee

  7. NAC hardware issues • Temperature drift in dewar (0.1K/day) User Committee

  8. NAC hardware issues • Higher read noise on spectrograph (80 e-) User Committee

  9. NAC hardware issues • Cooler vibrations from drive electronics User Committee

  10. NAC software issues • No scripting capability in observing command • No parallel port communication to LCVR controller • No communication to AO stepper motor • Small disk partition (33 Gbytes) for storing data • No system backup • Individual frames are stored as files • No dark/flat corrected real-time image • No processing capability (i.e. real-time spectroheliogram, LCVR calibration, focusing, etc) • Several annoying GUI bugs User Committee

  11. NAC future plans • Spectroscopy • 1-3 microns: working now • 3-5 microns: order new filters, work on systematic noise issues • Polarimetry • (1-3 microns): parts in house and currently testing – goal is Fall 2006 • (3-5 microns): line list identified, substrates identified – goal is 2006 test, early 2007 data, full system 2008. User Committee

  12. CCD Guider • Goals: • Test and verify TCS upgrade • Replace old limb guiders • Allow pointing to 1.5 solar radii • Provide full-disk solar image • Hardware: • One flat pickoff mirror between M1 and M2 • Beamsplitter, H-alpha filter, 2 imaging lenses, CCD camera and video, PC control computer User Committee
