1 Light Pollution Measured by the DSS-7 (Deep Space Spectrograph) Rose Haber http://farm1.static.flickr.com/61/212916043_7895484234.jpg Chicago, Illinois at night

2 Need Glare Light Trespass Harms wildlife Wastes government money -Cinzano, 2009 Vancouver http://farm1.static.flickr.com/101/285102672_4203221326.jpg

4 Light Pollution Misdirected or misused light Inappropriate application of exterior lighting products Light causing a glow over urban/suburban areas http://farm2.static.flickr.com/1293/554194288_965f5494cb.jpg

11 Spectrum of the night sky at Mound Ekar Observatory Natural sky lines/ artificial lighting http://adsabs.harvard.edu/full/2000MmSAI..71..235R Literature Review Proposal of a Spectroscopic Map of Astronomical Sites Rosoni, 1997

12 Literature Review Continued http://geoinformatics.sut.ac.th/sut/student/GISpresent/2006-1/light.pdf Modeling of Light Pollution in Suburban Areas Using Remotely Sensed Imagery and GIS Chalkias et. al, 2006

13 Literature Review Continued Coupling MOAO with Integral Field Spectroscopy: specifications for the VLT and the E-ELT Puech et al., 2002 http://arxiv.org/pdf/0808.1196v1 http://www.cfai.dur.ac.uk/new/spectroscopy/ifu_tech_s.jpg

14 Literature Review Continued Visual measurements and spectral survey of night sky brightness in Venezuela and Italy F. Della Prugna, 1999 http://aas.aanda.org/index.php?option=article&access=doi&doi=10.1051/aas:1999426

15 Purpose http://imgsrc.hubblesite.org/hu/db/images/hs-2002-10-c-web.jpg To examine the difference between the pollution of light in Manhasset, NY as opposed to the lack of pollution in Montauk, NY.

16 Hypothesis Null Hypothesis: no difference between the light pollution in both areas Alternate Hypothesis: light pollution will be greater in Manhasset than in Montauk http://imgsrc.hubblesite.org/hu/db/images/hs-2002-10-c-web.jpg

17 Methodology Light Pollution Measured by the DSS-7 Control: sky measured by DSS-7 in Montauk, NY Variable: sky measured DSS-7 in Manhasset, NY Procedure Spectrograph attached to the CCD imager, many images taken to examine types of light pollutants, images processed and stacked using Maxim DL software Measurement Measured once a week in Montauk and imaged, measured once a week in Manhasset and imaged over 7 months Analysis Graph/map of data collected Amounts vs. types of light pollution analyzed http://imgsrc.hubblesite.org/hu/db/images/hs-2002-10-c-web.jpg

18 Study done in accessible places –Manhasset, NY –Montauk, NY/ Upstate, NY CCD imager/DSS-7 easily portable Software downloaded for free off SBIG website/astronomy coolwiki Do-Ability http://imgsrc.hubblesite.org/hu/db/images/hs-2002-10-c-web.jpg
