  1. New Solar TelescopePost–Focus Instrumentation Carsten Denker, Haimin Wang, Guo Yang, Wenda Cao, Jun Ma, JohnVarsik, Sergey Shoumko, and Leonid Didkovsky Center for Solar–Terrestrial Research Big Bear Solar Observatory

  2. IRIM – InfraRed Imaging Magnetograph • Lyot–Filter • 1.56 m filter delivery delayed • He 10830 Å filter requires new polarizers, stuck in NJIT bureaucracy (open for bid, customs broker for Nanjing) • Jun is preparing a paper for Optical Engineering on achromatic wave plates for the next generation of Lyot–filters • Fabry–Pérot Etalon • Extensive testing at CfSR • Wenda is preparing a paper for Optical Engineering • NIR CMOS Camera • Delivered to BBSO in September, tested at Rockwell but no imaging data, yet • Some software is still missing, Wenda will test the camera at BBSO once the software is available • Systems integration at CfSR in winter 2003/2004 NJIT Center for Solar-Terrestrial Research

  3. RTIR – Real–Time Image Reconstruction • Delivered parallel computer to BBSO • Acquired a new dedicated 1024  1024 pixel, 12–bit, 15 fps CCD camera manufactured by Dalsa • First science observations on June 10th, 2003 (operating as a stand–alone system) • Integration into telescope control system in winter 2003/2004 • Improvement of FFT and s/n–calibration in winter 2003/2004 • Guo is expected to finish his PhD by the end of 2003 • Complete system will be available for 2004 observing season NJIT Center for Solar-Terrestrial Research

  4. RTIR – First Results Speckle reconstruction of active region NOAA 10375 on June 10th and 12th, 2003 obtained with the RTIR system. The Fried–parameter was r0 13 cm. NJIT Center for Solar-Terrestrial Research
