... HST Overview . ... ACS ISRs . ... The ACS/WFC CTE Correction Calculator corrects ACS/WFC aperture photometry for CTE losses using the most recent formula from Chiaberge's ISR 2012-05 and updated coefficients based on cycle 20 calibration data.This tool is only calibrated for photometry obtained after SM4 in May 2009. ... A new accurate CTE photometric correction formula for ACS/WFC (ISR 12-05) . ... Time Dependence of ACS WFC CTE Corrections for Photometry and Future Predictions (ACS ISR 2004-06) . ...

... An Astronomy Outreach Program for Navajo and Hopi Schools . ... Each of us works with one teacher at a different school, a different teacher at a different school each year. Throughout the year we make numerous visits to our chosen classes and perform hands-on astronomy activities with the class. ... Our outreach program is modest and one of several operating in Navajo and Hopi schools (others that we know of are run through Northern Arizona University and NASA's Jet Propulsion Laboratory). ...

... The Treasurer, Doug Milne, reported that the Society's reserves remained healthy, but that Sky & Space Magazine would be dropped as a Corporate Member since their membership was several years in arrears. The Editor reported on the state of submissions for Volume 16 of the Publications of the Astronomical Society of Australia (PASA) and commented again on the low level of submissions from the last scientific meeting. ... A final report and balance sheet from the 1998 Scientific Meeting was tabled. ...

... -instrument capability: manual at first; heading toward multi-port fast change capability [got it] Excellent pointing and tracking: 1 arcsec goal; can usually point to within ~few arcsec [or better] Excellent delivered image quality: 0.5 arcsec goal; often subarcsecond, but still feel we could improve about .3 arcsec [median seeing still about 1 arcsec ] Full suite of science instruments : Got them, upgraded them, have plans and paths to replace aging ...
