Convened at 8:30 for snacks and check-in
9:00 toured the mirror lab
10:45 official welcome by J.D. Garcia and Karie Meyers
At Stanford Solar site, you can request posters that convert to spectroscopes - class sets for free!
Dr. Chuck Claver - Large Synoptic Survey Telescope - please see his attached presentation for better
notes!
LSST is currently in building phase - 8.4 m scope - synoptic means "forming a comprehensive
summary"
More info at www.lsst.org
3.5 degree (!) field of view (compare to Gemini scope - 8 m, 0.2 degree field)
3.2 B pixel camera (gigapixels)
40 sec cadence - takes 2 15 second exposures
Full sky coverage every 4 nights
All data will be public!
Telescope location Cerro Pachon, Chile
Building modeled to eliminate turbulence of air flow from prevailing winds
Huge information throughput - much larger than any existing telescope
Cosmology standard model - about 5% of the universe is made of the familiar stuff, about 30% is
dark matter, about 65% is dark energy - so 95% is stuff we don't know much about!
Four major tasks:
1. LSST will allow study of dark matter/energy
By probing for weak lensing - how is the apparent shape of galaxies altered by intervening
materials?
2. Another strength will be looking for near-Earth objects, as well as more distant objects in our solar
system - will find 90% of potentially hazardous asteroids down to 140 m in 10 years of operations
3. Will make a "movie" of the visible universe - changes over time to see changes like supernovae
over time, etc.
4. Structure and history of Milky Way - look for evidence of "galactic cannibalism", predicted by
cosmological standard model - requires full mapping
Telescope and site group is based in Tucson, as if the data management group - the camera group
is based at Stanford
Leveling of Chile site started March 8, 2011
3 mirror optical design (Mersenne-Schmidt) - entendue 319 - primary and tertiary mirrors are in
the same piece of glass - a smaller, larger curvature tertiary mirror in the middle of the annular
primary middle
Primary/Tertiary mirror finished casting in July 24, 2008, now polishing - secondary mirror
completed 2009 by Corning
Camera's focal plane is 64 sm in diameter and contains 189 sensors, 3.2 Gpixels - camera lens is
1.6 m diameter
10 year survey is current plan (must keep consistent materials throughout)
Sensor development for camera at Brookhaven - in prototype phase currently- at the end of that
time, there may be a second generation project with some of the same instruments….
At the end of the 10 years, there will be 75 Petabytes of images (1PB = 1000 GB),plus 70 PB of
catalogs - accessible to all users, including the general public
Public involvement is required - lots of eyeballs needed to find all the discoveries that will be in
this data!

First light in 2018! Hopefully….
Executive Meeting - Present Ann Hammersly, Bob Culbertson, Rob Purington, Jim Ward, Tom Vining,
Buzz Delinger
Election of John and election committee
Fee-based meeting - $10 - charge for the meeting, fee waived for presenters
Next meeting September 24, 2011 - DMHS is possibility
Spring meeting March 24, 2012 - NAU
Themes? Possible presenters?
General Meeting minutes
Meeting begins @ 12:40 p.m.
David Weaver motions for John Griffiths to be voted AzAAPT president
James Ward seconds
Motion passed
Discussion on value/increasing attendance of meeting
David Katz (PCC) offers to do hands-on workshop (color, nanotechnology)
Contact Dept of Education on potential future of science requirements, maybe they present
Have a theme that remains throughout the day
Expand market to middle and elementary schools, related subjects at your own school
Executive committee have attaching rights to TCHRS Listserve (contact Jane Jackson)
Fall 2011 Meeting-Sept 24 at Desert Mountain High School
Suggested Themes: Nanotechnology, Material Science, Generating Interest in Science (Physics)
Workshop on how to recruit students to physics
Spring 2012 March 24 - NAU probably
Should we charge for the meeting to add value to meeting?
-Might be regional based (Flagstaff)
-Adds to the planning that needs to happen
-Charge but refund if they attend
-Attending meeting get membership dues waived
Tom Vining motions to charge $10 registration fee for next meeting in Phoenix
Karie Meyers seconds
Tom Vining motions to amend motion that presenters exempt from registration fee, pre register is
$10, at the door $15, and covers cost of year membership.
Motion passed
Election committee
