From the NSO Director's Office (1Sep95) (from NSO, NOAO Newsletter No. 43, September 1995) This quarter continues to show great activity at NSO. Personnel changes, GONG deployment, telescope/instrument improvements, and the by-now-usual budget reduction exercises take a prominent place. This quarter included the annual presentations of plans and progress at NSF, presentations at the AURA Board meetings, at the Solar Physics Division meeting, and at the AURA Observatory Council meeting. The AURA Observatory Council and the AURA Executive Committee met at Sac Peak. GONG Deployment Continues The Tenerife, Learmonth, Mauna Loa and Tucson GONG stations are now operating successfully as an extended "GONG mini-network." The CTIO, Big Bear and Udaipur sites are being prepared; the instruments are being shipped to, or have already arrived on, these sites for an anticipated full deployment of all GONG stations by the end of September. Relatively minor "teething" problems have been overcome, and quality data are being received at the Tucson data processing facility for analysis and distribution to the GONG users. Keller Joins NSO Staff I am most pleased to announce that on July 1 Christoph Keller joined the NSO staff. Christoph had already been with us for 18 months as a postdoc funded by the Swiss National Science Foundation. His research centers around the physics of the smallest observable structures in the solar atmosphere and on precise differential solar photometric techniques. His earlier high angular resolution observations using differential speckle interferometry are well known. Recently Christoph, often in collaboration with others, has obtained outstanding observations of solar surface structures using phase diversity techniques, line polarization at visible and infrared wavelengths, and the green- and red-line corona. Christoph will be living in Tucson. His service functions will center around NSO/KP, but he expects to carry on his research at both NSO/KP and NSO/SP. VTT Images Continue to Improve Continuing improvements of the thermal control of the VTT window have started paying off in improved images. At his latest observing run, Thomas Rimmele broke the 0.2" resolution barrier with images showing structures of 0.15" in size near sunspots at 470 nm. Using image selection techniques, high quality images can be obtained at many times during the day. Keller, in collaboration with Seldin and Paxman, using phase diversity image reconstruction techniques, obtained outstanding time sequences of the solar surface structure in and near the Ha and the Mg b-lines. Radick and Rimmele obtained year-end funding from the USAF Phillips lab to purchase a deformable mirror. Together with his development of a relatively slow Hartmann-Shack wave-front sensor, Rimmele plans to implement an active optics system at the VTT to remove the residual optical aberrations in the telescope. It is rapidly becoming clear that diffraction from the 76 cm VTT aperture is becoming the limiting factor in doing solar research at Sac Peak. Even in the best images, many structures remain unresolved. FY 1996 Budget Issues The internal NOAO budget planning for FY 1996 is starting unusually early this year. The outlook is for another 5 to 6% budget reduction (including inflation) for NSO in this next fiscal year. This follows the two 5% cuts that NSO had to absorb already since I took up my position less than two years ago, and precedes additional, similar annual cuts for a number of years to follow. Although not as drastic as the budget reductions NASA funded institutes are facing, these cuts present a major challenge to the NSO program. "Doing more with less" is a good slogan, but it requires magic to make it happen. In this ever decreasing budget environment, it is essential to have a clear image of where we want to be heading, so that a targeted restructuring of the program is possible. In the meantime, efforts in attracting separate resources to support important activities at NSO, which are less central to NSO's future goals, have been successful at least as far as the support of the laboratory astrophysics/chemistry program for the McMath-Pierce FTS goes. A substantial grant from the NSF Chemistry Division will guarantee the health of that program for at least three years to come. The continued funding for the Solar-Stellar program at the McMath-Pierce in FY 1996 is still uncertain. It was removed from the NSO budget in FY 1995 in response to the previous budget cut, and is supported presently with separate funds from the NOAO Director's office. The additional 5 to 6% budget cut for FY 1996 mentioned above will not allow reinstatement of that program; in fact, it will result in an additional restructuring of NSO so that it can best fulfill its mission even at a lower support level. The Restructuring of NSO As already mentioned in the last Newsletter, AURA is asking NSF to commission a high-level study of the future plans for ground-based solar astronomy, probably by the National Academy of Sciences/National Research Council. NSF has responded favorably to that request, and such a study will probably be started in the near future. To prepare for that, the AURA Observatory Council (previously named the Observatory Advisory Committee) has formed a Solar Subcommittee, which includes as non-NSO scientists Art Walker (chair), Bob Rosner, Alan Title, Juri Toomre and O. Richard White. It is expected that this committee will meet soon together with NSO/NOAO staff (J. Beckers, J. Kuhn, D. Rabin, and S. Wolff) and M. Knoelker (HAO Director). In the meantime, a number of activities are being pursued within NSO that will probably be components of any restructuring of the observatory. As described in my report at the recent Solar Physics Division meeting in Memphis, our current planning is based on three legs. The first leg focuses on making our existing facilities work as well as possible (better imaging, better detectors, best GONG commissioning and operation, implementation of RISE/PSPT). The second leg focuses on making a major breakthrough in the next decade and a half in our understanding of the solar activity cycle and its effects on earth using GONG, RISE/PSPT and our existing synoptic facilities. The third leg aims at the creation of a major new solar research facility for individual research projects. Restructuring within NSO aims at making our facilities both more economical to operate and more capable. Jack Harvey and Larry November are presently taking the lead in defining a better, more economical solar synoptic facility to be part of the second leg. As part of the third leg, Jeff Kuhn, Don Neidig, Doug Rabin, Thomas Rimmele, Ray Smartt and myself are pursuing the study of the CLEAR telescope concept, a 4-meter-class aperture telescope capable of high angular resolution studies of both the solar disk and the solar corona at wavelengths ranging from the visible to the far infrared.
