Behlen Observatory public night is Sept. 27
The Department of Physics and Astronomy will host a public night at Behlen Observatory from 8 to 11 p.m. Sept. 27.
The evening will feature the last eclipse in a series of four lunar eclipses over the past two years, known as a tetrad. Photos of past lunar eclipses and other astrophotography done in Nebraska are available online.
"Tetrads happen every 10 years or so this century, but there were no tetrads from 1600 to 1900 so we are in the middle of an interesting time for lunar eclipses," said Shawn Langan, lab manager with physics and astronomy.
Behlen Observatory near Mead, Nebraska, has been in operation since 1972 with dozens of publications credited to it.
