Canary Islands' Facilities for Support of the Deep Impact Mission
Mark Kidger Instituto de AstrofÌsica de Canarias



Telescopes in La Palma
· Large suite of telescopes available
­ 4.2-m, 3.6-m, 2.56-m, 2.5-m, 2-m, 1.2-m ­ 11.4-m Gran Telescopio CANARIAS (GTC) possibly available during commissioning phase. ­ Future of the 1-m telescope uncertain.

· Wide range of instrumentation in the visible and near-IR. Mid-IR options may be available for an impact campaign, if required. 90% usable nights during summer. 70-80% photometric nights in summer.


Telescopes in Tenerife
· Three nocturnal telescopes available
­ 1.5-m ­ Near-IR imaging or photometry ­ 1-m ­ Visible imaging ­ 82-cm ­ Visible imaging

· The 82-cm will receive a major upgrade during 2004, with a new CCD camera. · The 1.5-m will receive a new photometer. · Service mode available in 82-cm
­ Up to 2 hours per night, 2-3 nights per week for monitoring programmes.


International Time Projects
· Give access to 5% of the time on all the common-user nocturnal telescopes in Tenerife and La Palma. · Designed for large science projects that require monitoring of an object or objects over time. · Equivalent to approximately 7-8 nights on each of 9 telescopes over 6 months. · Call for proposals for Spring/Summer 2005 in November 2004.
­ Deadline for proposals is late 2004. ­ Observing time starts in February/March 2005.


A Summary of Instrumentation
· A brief review of the most interesting instrumental options. · Many more instruments are available.


4.2-m William Herschel Telescope
· ISIS ­ Intermediate dispersion spectrograph
­ Two arms (blue and red) ­ 300-1000nm ­ 0.11-2.90å/pixel

· LIRIS ­ 0.9-2.4 micron imaging spectrograph
­ ­ ­ ­ R= 1000-3000 0".25/pixel 12 broad and narrow bands Polarimetry


4.2-m William Herschel Telescope
· If we were to observe the impact itself...
­ ULTRACAM ­ 3 CCDs, simultaneous RGB ­ Very high time resolution several Hz (can be > 10Hz) ­ Small field of view (best time resolution requires 2 windows ­ nucleus + ref star ­ 10-15" each).


3.6-m Galileo National Telescope
· NICS ­ 0.9-2.5 micron spectrograph
­ R= 50-2500 ­ 4'.2 field of view

· SARG ­ 370-900nm highresolution spectrograph
­ R= 29000-164000 ­ Long slit (30") ­ Polarimetry available


2.56-m Nordic Optical Telescope
· Exceptional image quality · ALFOSC ­ Imaging grism spectrograph
­ 320-1100nm ­ R= 190-4500 ­ 0".19/pixel

· SOFIN
­ High-resolution echelle spectrograph


2.5-m Isaac Newton Telescope
· Wide field prime focus camera
­ ­ ­ ­ 4 x 4kx2k mosaic 0.33"/pixel 35' field of view Broad and narrow filters

· This telescope will probably be closed on July 31st 2005... Deep Impact would be its sendoff party!


2-m Liverpool Telescope
· Robotic telescope
­ 2 048x2048 ­ 0".135/pixel camera with Sloan filters ­ 4' field of view

· 1-2.5 micron NICMOS-type camera
­ 2 56x256 ­ 0".4/pixel


1.2-m Mercator Telescope
· · · · Cassegrain CCD 6'.5x6'5 field 0".2/pixel 16 filters


1.5-m Carlos SÀnchez Telescope
· Dedicated infrared telescope. · NICMOS-type detector. · 0".4 or 1"/pixel. · 80"/4' field of view (interchangeable). · JHKKs + narrow band (CO, Kcont, ...). · High frame rate (> 10Hz with windowing). · New monochannel photometer available in summer 2004.

Can observe bright objects in narrow-band in daylight at 2 µm.


1-m OGS
· · · · ESA Telescope 4096x4096 camera Field of view 50' Single, fixed filter


82-cm IAC-80
1024x1024 CCD 0".4/pixel 7'.1 field of view 8 broadband and narrow filters may be mounted simultaneously. · Major upgrade of the CCD camera in 2004. · Long-term service mode available for monitoring. · 2hrs/night, 2-3 nights per week (can be more nights is interest is great). · · · ·


11.4-m Gran Telescopio CANARIAS (GTC)?
· May be available during telescope commissioning phase. · Probably equivalent to a 6-m mirror. · Commissioning camera and Intermediate Dispersion Spectrograph. · Request direct to Director.


Why the Canaries?
· · · · 9P will be a northern hemisphere object. Wide range of telescopes and instruments Excellent weather conditions (summer!). Deep Impact is ideal for an International Time P roject that would give approximately 70 nights of telescope time for monitoring over a 6 month period. · High probability of success for proposal.
