HATC - Hat Creek Radio Astronomy Obs., Cassel, CA, USA

Location

The site is located at Hat Creek Observatory, operated by the Radio Astronomy Laboratory of the University of California. Hat Creek is located near Mt. Lassen in Lassen Volcanic National Park, in Northern California.

Location of Hat Creek station

This station is part of a collaboration between the Berkeley Seismological Laboratory and the Radio Astronomy Laboratory. This station was installed in May 2005 by USArray personnel as a collaboration with the Berkeley Seismological Laboratory, and was part of the USArray component of the Earthscope program. When the Travelling Array left California in 2007, the BSL adopted this station. It has been operating as a BDSN station since May 2008.
