Halley Radar Operational Again

After a long (but intentional) outage, the Halley radar PI, Dr. Mervyn Freeman, has announced that the radar resumed operations earlier today. This is due to the hard work of the British Antarctic Surevy (BAS) hardware and software engineers Neil Cobbett, Nick Alford, and Paul Breen, the Halley winterer Oliver Bonner, and others.
Things seem to be running ok except for some higher than normal noise that is likely interference from the nearby MF radar, which is being investigated.
The Virginia Tech Team congratulates Mervyn and his colleagues on their success!
The Halley radar was turned off December 15, 2007 and dismantled in order to be relocated with the rebuild of the Halley BAS station at another location. (These moves are carried out periodically owing to the advancing ice sheet.) As the building was going to take several years to complete, it was decided to operate the radar from a site in the Falklands, thereby providing mid-latitude measurements that are conjugate to mesurements made by the northen mid-latitude radars (Wallops, Blackstone). A site was found in the Falklands and an array of antennas built. The Halley electronics powered the system from a shed. Now the electronics have returned to Halley station to be incorporated in the rebuilt radar, which resumed operation on February 24, 2011. It is hoped that a new set of electronics can be lined up to return the Falklands site to operation. The Falklands Islands SuperDARN radar operated from February 2010 until September 2011.
