Spaceguard Seismic Station
The Brown Clee station has since been duplicated and installed at 'Spaceguard' Knighton Powys. This seismic station was installed in March 2003 and is in a quiet environment so false alarms are very rare. There have been no problems with this station apart from a transmitter failure caused by a single electronic component. The apparatus is solar powered but consumes rather more power than the Brown Clee station due to a weather station (RAWS) running on the same battery bank. During the winter months a wind generator is temporarily installed at the site to supply additional power as solar energy becomes insufficient to power the station.
Below we see the seismometer and amplifier/modulator housed
in the 300 mm diameter tube. The seismometer sits at the base of the tube
on a concrete slab which is in direct contact with the underlying limestone
rock forming the part of the Cambrian mountains. The direct contact with
the rock adds great sensitivity to the seismometer and the quiet location
of the site makes for the perfect location of this station.
