NASA Infrared Telescope Facility Observing Proposals

NASA Infrared Telescope Facility Observing Proposals, Due date for the 2012B semester (August 1, 2012 to January 31, 2013) is Monday, April 2, 2012. See our online submission form. Available instruments include: (1) SpeX, a 1-5 micron cross-dispersed medium-resolution spectrograph (up to R=2,500) and imager; (2) CSHELL, a 1-5 micron high-resolution spectrograph (up to R=40,000); (3) NSFCAM2, a 2048x2048 pixel, 1-5 micron camera with a 0.04"/pixel scale (82"x82" field-of-view) and a circular variable filter; (4) MORIS, a 512x512 pixel Andor CCD camera mounted at the side-facing, dichroic-fed window of the SpeX cryostat (60"x60" field-of-view); MORIS can be used simultaneously with SpeX, and (5) PI-instruments including a low-resolution 3-14 micron spectrograph and high-resolution spectrographs for 8-25 microns. Information on available instruments can be found at:

Important notice: We are planning to take NSFCAM2 off line during Aug. - Oct., 2012, to install a new infrared array and control electronics. We expect it to be available starting on Nov. 1, 2012. Due to the schedule uncertainties in returning the instrument to service, proposals to use NSFCAM2 will be accepted provided the program can be also accomplished with the SpeX slit viewer, which has 0.12"/pixel and a 60"x60" field-of-view.

Important notice: We anticipate that SpeX will be taken off line during June - Oct., 2013, and will be available Nov. 1, 2013. This is necessary to upgrade SpeX with new arrays and array controllers. We strongly recommend observers to plan their observing accordingly. We also expect to accommodate key projects requiring large amounts of observing time using CSHELL, NSFCAM2, and visitor instruments during the time SpeX is not available.

Visitor instruments (available on a collaborative basis with the instrument team) include: TEXES (5-20 micron high-resolution spectrograph; contact Matt Richter at for more information), BASS (3-14 micron spectrometer; contact Ray Russell at, and CELESTE (5-25 micron echelle spectrometer; contact Don Jennings at

Remote observing is available with SpeX, NSFCAM2, CSHELL, MORIS.

Important notice: Remote observing requests must be made in the proposal application - later requests will be considered if requested at least ONE MONTH ahead of time. If you wish to observe from your home institution, you MUST comply with the requirements for video conferencing and instrument operation provided on the Remote Observers Information page. First-time users should plan to work in Manoa, Hilo or at the summit for their first run with their support astronomer and become familiar with the instrument operation. Observers already familiar with the instrument and who want to observe remotely from their home institution are strongly encouraged to contact Miranda Hawarden-Ogata ( to set up a test of the video link and user interface at least one month prior to their observing run. We cannot guarantee a successful remote observing connection on short notice since we have no control of hardware and software compatibility on the user's side. It is the responsibility of the PI to provide up to date observing contact information.

To keep our bibliography up to date, and to insure future funding of the IRTF instruments, we ask that you send us your latest publications or update your publications list using our website bibliography page for refereed and unrefereed papers; (refereed publications) (unrefereed publications)

Please send to William Walters ( any missing references, and please include in your paper the acknowledgment to the IRTF and the name of the instrument used.
