First radar light for KAIRA

Well done to our colleagues at KAIRA (Kilpisjärvi Atmospheric Imaging Receiver Array) - the LOFAR-based project in Finland - who last Friday achieved their first radar light.
Using the EISCAT VHF transmitter at Ramsfjordmoen, near Tromsø, Norway, they transmitted a single 1.28ms long pulse. Using the multi-beam capability of the LOFAR-KAIRA system, they pointed at 31 common volumes along the transmission path and detected weak ionospheric plasma scatter. They have also now detected space debris and meteor echoes too.
Their initial spectrum is shown below. More information can be found on the KAIRA website.
