Facilities
• Blanco 4m Telescope (90%)
• SMARTS 1-5-m + 1.3-m + 0.9-m (33% 2003, 25%
2004)
• SOAR 4.1-m (30%, first light April 2004)
Not available to NOAO Users
• Schmidt 0.6/0.9m (U. Michigan only - satellite debris program)
• Yale 1.0-m (closed 2003)
• Lowell 0.6-m (closed)

Blanco 4-m
• Instruments (Mosaic, ISPI, Hydra, RC Spec,
Echelle) block-scheduled, all classical mode
• Mixture of multi-semester Survey (~20%) and short
(~80%) allocations
• La Serena Operations Room - Super Macho &
Essence Programs; Instrument support via VNC
• Mosaic super-popular; ISPI a slow start but 2004A
looks good; continuing steady demand for the
spectrographs

Some large programs 2001B-2006B
• Essence (Suntzeff): 65 nights
• Microlensing (Stuubbs): 65 nights
• Deep lens survey (Tyson): 39 nights
Over 2001A-2003B: 21% of available nights (after engineering and Chile time
removed) are pre-assigned.

Blanco Instrumentation 2003-2005
• Mosaic Imager, ISPI and Hydra can be a set of permanently
mounted instruments
• RC Spec still a popular workhorse - Goodman spectrograph
on SOAR will be superior
• Echelle also has a steady demand - users will migrate to
Gemini HROS? Or to the Brazilian Echelle (STELES) on
SOAR?
POLICY
• Minimize instrument changes
• Retire uncompetitive instruments
• Plan maintenance and upgrades

Blanco Issues
• Instrumentation
- Mosaic CCDs - vulnerable to failure
- Fixed instrument complement situation not reached
- Available scientist time not consistent with
instrumentation offered: Blanco 1.5 FTE,
SOAR 0.5 FTE, SMARTS 0.1 FTE
• Telescope
- Dedicated telescope scientist (Abbott)
- Large list of fixes and upgrades needed, e.g. primary
mirror edge supports - will prioritize and work
our way through them
- New TCS - copy SOAR?

SOAR Issues
• Need to commission instruments and telescope
together (not a usual problem!)
• Overly-ambitious instrumentation program
But
• Lots of preparation
• Experienced instrument builders and teams
