EB, RR Lyrae pageheader

This page contains visual observations of eclipsing binaries, made with telescopes in the 8 to 10 inch range, easily within the grasp of amateur astronomers. One or two of these observations were made with binoculars. For further information on eclipsing binaries in general, see the EB page.
Visual magnitudes are obtained by comparing magnitudes with nearby stars of known magnitude. Step magnitudes are values obtained by comparing magnitudes with nearby stars whose magnitudes are arbitrarily assigned.
Magnitudes are shown on the vertical scale, time on the horizontal scale. The interval between time hacks is about 30 minutes.
