With CalFUSE 3.0 we introduce a fundamentally new implementation of the FUSE pipeline. In this version relevant information for each detected photon is stored in a special 'Intermediate Data File'. In addition to position and arrival time this file also contains the photon wavelength, the aperture through which the photon passed and all information needed to correct for detector distortions, astigmatism, spacecraft motions and variations in the grating and mirror positions. For TTAG data each photon is also associated with a set quality flags which indicate whether the data has been compromised in any way. These flags mark photons observed during the day as well those which are detected during a burst, an SAA passage or too close to the limb of the earth. This format allows the maximum flexibility in manipulating the data and extracting the spectra. The IDL based program `CF_EDIT' has been developed to allow the user to interactively screen and combine the individual exposures within an observation, extract the spectrum and display the results. We will bring laptop computers with CF_EDIT installed to show any interested FUSE users the current state of this tool. CalFUSE v3.0 and the CF_EDIT tool are currently undergoing beta testing and will be released in the near future. 2) FUSE Cycle 5 Selections to be Announced Before Atlanta AAS Meeting NASA has completed the review and selection of FUSE Cycle 5 proposals. Informal notification will be sent by e-mail to the proposal PIs before the AAS meeting. The official letters from NASA with the review results should be mailed in early January. For accepted programs, phase 2 templates will be send out by January 23 and the deadline for returning verified and/or corrected phase 2 forms back to the FUSE project at JHU will be February 23, 2004. 3) Happy New Year! We at the FUSE project hope that you have had a pleasant holiday season and wish you all a happy and productive 2004.
