Finally, Mark Krumholz (UC Santa Cruz) was awarded a 2009 Sloan Fellowship. He joins
Alice Shapley (UCLA), Tomaso Treu (UCSB) and Josh Bloom (UCB) as current Sloan Fellows.

Congratulations to all.

Mt Hamilton

I'm happy to report progress on many fronts at Mt Hamilton. As of August, the 3m and 1m telescopes are now remotely accessible and increasingly used in that mode. The 3m was used remotely approximately 30% of the time and the 1m approximately 85% of the time in 2008. UCO has now provided Lick/Keck remote stations at eight of the campuses. Bob Kibrick at Santa Cruz has been the mastermind of this effort and it has been successful beyond all expectations.

This is the 50th anniversary of first-light for the Shane 3m and we are planning the summer visitor events around this and the 400th year of the telescope.

Kast Spectrometer: We received a generous gift from Bill and Marina Kast which allowed the purchase of a new CCD for the blue-side camera of the Kast Spectrometer and funded much of the work we have carried out in the last 6 months on the spectrometer. The Kast was brought to Santa Cruz for 9 weeks in early 2009 as the final stage of a complete updating with new motor control software, a thorough cleaning and tuning, new CCD controllers, new optics coatings and careful alignment of the optics.

3m Control Room and Kitchen: The remodel of the 3m kitchen is now complete! We also closed down observing at the 3m for two weeks in February to remodel the 3m control room. That project went well and the result is a big improvement.

Automatic Planet Finder (APF):
The APF telescope had first light at the EOST factory in Tucson late last Fall and passed Factory Acceptance Tests in February. The telescope is now packed for shipping and due to arrive at Mt Hamilton on April 6 (!). We are on a very tight schedule for signoff by USNO and the Navy before June 30, 2009. There has been a large amount of heroic work going on in the background to work with EOST to bring this facility on line. A crew from EOS has been at Mt Hamilton completing the final punchlist items for the dome and that will be ready for installation of the telescope. The Levy Spectrometer has been largely completed in Santa Cruz for the last 6 months.

A new telescope at Mt Hamilton is an exciting event. This particular facility--a system optimized for extra-solar planet discovery and dedicated to that purpose--is extraordinarily exciting.

Super-LOTIS: We obtained 50% access to a robotic imaging telescope at Kitt Peak and the initial interest has been very high. This is an 0.6m telescope originally sited in what is now the KAIT dome at Mt Hamilton. It is robotically queue scheduled for direct observations in five filters and with a 17 x 17 arcminute field. For now, Associate Director for Lick Observatory Burt Jones will make a call for proposals via e-mail each semester. There is an out-of-date WWW site describing the facility. We will shortly have a link at the UCO WWW site with more UC-relevant information.

LRIS-Red Upgrade: The LRIS-R upgrade is nearly complete and on schedule for installation May 11. The science-grade CCDs are installed in the dewar in Santa Cruz and everything looks good. A team from Santa Cruz went out in mid-March to do a test fit of the new focus mechanism and various electronics boxes. As discussed in earlier newsletters, the new devices will have much higher quantum efficiency than the current device for wavelengths longer than 680nm and have no fringing at any wavelength.

MOSFIRE: All of the MOSFIRE optics have now been fabricated, coated and delivered, retiring a significant risk. The special reconfigurable slit unit has been built and successfully cold tested in Switzerland. MOSFIRE had its first two overall cooldowns. First light is currently scheduled for April 2010.

Next Generation Adaptive Optics, NGAO: After the generally very successful external review of the project, concerns over the large price tag and current economic uncertainties led to a reconsideration of the NGAO program. A fixed price in as-spent dollars for the system plus instruments was imposed and the team reviewed the concept and made adjustments to the scope. The B2C (build to cost) version of NGAO was reviewed in a meeting in March 09 at LAX. The resulting concept remains an exciting future for Keck AO.

Keck Observatory Scientific Strategic Planning: The Keck Science Steering Committee has been leading an effort to update the Scientific Strategic plan for the observatory. There was a call for white papers on future capabilities for Keck and Jason Prochaska organized several video-based telecons to gather wide input for the updated Strategic Plan. A planning meeting was held in Half Moon Bay in the Fall of 2008 with members of the SSC, Keck Observatory leadership, CARA Board representatives and additional representatives from the UC, Caltech, NASA and University of Hawaii communities. Good progress has been made on identifying priorities for future capabilities, including new observing and scheduling modes. The completion of the Strategic Plan, including another round of input from the community, was sidetracked by the demands of the Astro2010 panels. It will be back on the front burner later this Spring.

The TMT project is nearing the completion of its design development phase and moving into early construction activities. There is much going on on many fronts, I'll report on just a few of
the activities here.

WFOS/MOBIE: Rebecca Bernstein (PI) and Bruce Bigelow (Project Manager) have developed a very compelling concept for the wide-field optical multi-object spectrometer for the TMT. In addition to a traditional LRIS/DEIMOS-like multi-slit, single spectral order mode, "MOBIE" has an echellete mode for which spectral coverage can be traded off with number of objects observed. The field of view for the MOBIE concept is ~9.5' x 4.5' and the spectral resolution for different options ranges from R~1000 to R~8000 with 0.75" slit width. This instrument passed an external review for feasibility in December 2008 with flying colors and is now in Conceptual Design phase.

Primary Mirror Segments: The TMT segment size is very similar to that of the E-ELT 42m telescope. This works out well for maintaining some competition between companies engaged in manufacturing segments. There are four companies currently developing the process for producing segments and doing so in a mass-production mode. We are expecting the first completed segment for TMT before June 2009.

Site: The decision on site for the TMT is still set for the July 2009 TMT Board meeting. In Chile, the equivalent of an Environmental Impact Statement study was completed and accepted and TMT now has legal status in the country. In Hawaii, the draft EIS work is being completed and on schedule to be submitted in May 2009. Before this, there will need to be an approved Comprehensive Management Plan (CMP) for Mauna Kea. The Office of Mauna Kea Management and consultants have been working hard for more than a year preparing the CMP. The draft plan was recommended for approval by the Mauna Kea Management Board in March and will go before the Land Board in April. I have personally been involved with the preparation of the draft EIS for TMT at Mauna Kea and am proud of the attention being paid to address the many environmental and cultural concerns associated with this unique place.

Partners: We remain enthusiastic about the idea from the 2000 Decadal Survey of a private-public partnership for the TMT. At the end of April, the NSF is conducting a readiness review of the TMT and GMT to evaluate the progress of each project toward fulfilling the 2000 Decadal Survey vision of a US Giant Segmented Mirror Telescope. This, plus the stimulus package of 2009 which has specified an additional $400M to go to the NSF MREFC program (which funds projects of the scale of ALMA, GSMT, ATST and LST), is an encouraging step toward realizing an NSF share. In addition, the TMT has hosted delegations from China and India and TMT representatives have made trips those countries to discuss mutual interests in partnering on the TMT construction and operations.

Joe Miller: Finally, I'd like to take note of Joe Miller's retirement at the end of February 2009 after 41 years at UC Santa Cruz. In addition to his distinguished career as an astronomer and astrophysicist, Joe was the UCO Director for 14 years. Although it was Bob Kraft's vision that resulted in UC involvement in the Keck Observatory, Joe played a crucial role in making that vision the terrific success it has been. Joe continued to set the aspirations for University of California astronomy at world-leading heights as one of the principal forces behind the CELT and then TMT projects. His leadership and long excellent record of service to UC and astronomy are very appreciated.
