  Title A Simple, Portable Apparatus to Measure Night Sky Brightness at Various Zenith Angles Type Journal Article
  Year 2010 Publication The Journal of the American Association of Variable Star Observers Abbreviated Journal  
  Volume 38 Issue Pages 221  
  Keywords Remote Sensing  
  Abstract We describe a simple apparatus for making measurements of night sky brightness as a function of zenith and azimuth using “off-the-shelf” equipment: a Unihedron Sky Quality Meter with Lens, a protractor with plumb-line, a tripod, and a hand-held compass. Compared to a photoelectric or CCD photometric system, this apparatus is simple to set up and use and does not require complex data reduction procedures. Thus, this apparatus makes measurements of night sky brightness as a function of zenith and azimuthal angles quite amenable to students.

  Title The Light at Night Mapping Project: LAN MAP 1, the Tucson Basin Type Journal Article
  Year 2012 Publication Society for Astronomical Sciences 2012 (proceedings) Abbreviated Journal  
  Volume 31 Issue Pages 139-145  
  Keywords Skyglow  
  Abstract Tucson, Arizona, once billed as the Astronomical Capital of the World, has long been home to at least ten major astronomical institutions and facilities. The region also hosts numerous productive amateur observatories and professional-amateur astronomical collaborations. In spite of the implementation of progressive night time lighting codes, the continued growth of the region has arguably deprived Tucson of its title, and threatens the future of some if not all of these facilities. It has become apparent that there are several difficulties in regulating this lighting environment. It is not easy to model the actual effects of new or changed lighting fixtures, there are compelling economic conflicts that must be considered, and adherence to various guidelines is often ignored. Perhaps the most fundamental problem is that there have historically been no comprehensive measures of either light at night or sky brightness over the extended growth areas. What measurements do exist are inhomogeneous and poorly accessible spot measurements at some observatory sites. These have little to tell us about the actual light distributions in the overall region, and rarely are informative of the specific light sources that offend the observatory sites. Tucson remains, for the time, an important astronomical resource. Because of its astronomical and lighting code circumstances, it is an interesting and valuable laboratory for studying these issues. In this paper we introduce an innovative new 5-year project to comprehensively map both sky brightness and associated artificial lighting over extended areas of development in the vicinity of important astronomical institutions. We discuss the various vectors employed in data collection; we outline the protocols used for each methodology, give examples of the data collected, and discuss data analysis and conclusions. This program has been underway since January 2012, and has already produced results of interest to professional and amateur astronomers alike.

  Title Sky Brightness at Zenith During the January 2019 Total Lunar Eclipse Type Journal Article
  Year 2019 Publication The Journal of the American Association of Variable Star Observers Abbreviated Journal  
  Volume 47 Issue 1 Pages 94  
  Keywords Skyglow  
  Abstract Lunar eclipses occur during the full moon phase when the moon is obscured by Earth's shadow. During these events, the night sky brightness changes as the full moon rises and then passes first into the penumbral and then the umbral shadow. We acquired sky brightness data at zenith using a Unihedron Sky Quality Meter during the 20-21 January 2019 total lunar eclipse as seen from Morehead, Kentucky. The resulting sky brightness curve shows an obvious signature when the moon enters the umbral (partial) eclipse phases and the total eclipse phase. During the total eclipse phase, the brightness curve is flat and measures 19.1 ± 0.1 mag / arcsec2. The observed brightness at totality is close to typical new moon in January night at our location, which measures 19.3 ± 0.1 mag / arcsec2. The partial eclipse phase is symmetric on either side of totality. The penumbral phase is more difficult to identify in the plot, without comparison to a typical full moon night. There is a clear asymmetry in the curve just before and just after the umbral phase. This asymmetry is probably due to changes in terrestrial atmospheric conditions, such as high altitude clouds.
