TY - JOUR A1 - Hernitschek, Nina A1 - Schmidt, Elmar A1 - Vollmer, Michael T1 - Lunar eclipse photometry: absolute luminance measurements and modeling T2 - In: Applied optics 47 (2008) 34, pp. H62-H71 N2 - The Moon’s time-dependent luminance was determined during the 9 February 1990 and 3 March 2007 total lunar eclipses by using calibrated, industry standard photometers. After the results were corrected to unit air mass and to standard distances for both Moon and Sun, an absolute calibration was accomplished by using the Sun’s known luminance and a pre-eclipse lunar albedo of approximately 13.5%. The measured minimum level of brightness in the total phase of both eclipses was relatively high, namely −3.32 mvis and −1.7 mvis , which hints at the absence of pronounced stratospheric aerosol. The light curves were modeled in such a way as to let the Moon move through an artificial Earth shadow composed of a multitude of disk and ring zones, containing a relative luminance data set from an atmospheric radiative transfer calculation. © 2008 Optical Society of America Y1 - 2014 UR - https://opus4.kobv.de/opus4-fhbrb/frontdoor/index/index/docId/531 SP - H62 EP - H71 ER -
