During the year Dr Denis Sullivan (Victoria Univer- sity of Wellington) visited Mt John on six occasions to carry out high-speed time-series photometry of two pulsating white dwarfs using his portable 3-channel photometer attached to the McLellan Telescope. In January, Dr Murray Forbes used the same telescope for CCD photometry in Vilnius and VRI passbands of various open Optical layout of the SALT HRS spectrograph.

Instrumentation The HERCULES high-resolution spectrograph continued as the principal instrument used on the McLellan Telescope. Frost installed a remote focusing mechanism for the detector used with this instrument, which cur- rently is the Photometrics Series 200 CCD system incorporating a 1024×1024-pixel SITe CCD. At year’s end a detector that will cover the entire focal plane was ordered from Spectral Instruments in Tucson. It will con- tain a 4k×4k Fairchild 486 CCD chip. Mechanical layout of the SALT HRS.

Testing of the which the Department expects to build for SALT, the design team of Cottrell (PI), Albrow (HRS Project Scien- tist), Barnes, Kershaw, Frost, and more recently Ross Ritchie & Geoff Graham, have worked to develop a design based on an R4 echelle´ grating, as recommended in 2003 at Preliminary Design Review (PDR) of an initial R2 design. Others involved in the design process are Damien Jones (Prime Optics, Australia), Graham Hodge (Unilogix Ltd, Christchurch), Peter Connor (KiwiStar Optics) and Dave Cochrane (Industrial Research Ltd). The design involves two beams, one for blue wavelengths (380–550 nm) and the other for red (550–890 nm). Doz- ens of documents were produced preparatory to a second, succesful PDR in July. Detailed development of the design has now begun towards Critical Design Review in 2005 April. If approval is given, the 18-month construction phase will then begin.

Other Research Albrow and Pollard continued their research with the PLANET collaboration on detailed follow-up observations of microlensing events. They controlled operations in July; over the year, 125 events were followed up using telescopes in Australia, South Africa and Chile. Albrow developed a new Bayesian technique for predict- ing the peak amplification of microlensing events from early, pre-peak data. In January he described this work at the Hawaiian Gravitational Microlensing Workshop. His method was implemented as a web-based system and used by PLANET for event prioritization. Kilmartin and Gilmore continued the service observing programme on the Optical Craftsmen 0.6-m telescope using the photoelectric photometer. They recorded 287 Opening the MOA 1.8-m telescope on December 1 observations of 22 stars, including novae as well as sev- eral R Coronae Borealis and RV Tauri type stars.
