There is currently an opportunity to view the British Aircraft Corporation-Aerospatiale Concorde 101 out in the open at the Imperial War Museum, Duxford Airfield (11 km NNE of Royston), whilst its previous location of Hangar 1 is making way for the new AirSpace hangar due to open in 2007. In this picture Concorde is seen at 1439 GMT on 6th June 2006. The Concorde flew into Duxford in 1977 just before the runway was truncated by a new motorway (M11). A feature of the weather on the airfield that day was the exceptional brightness, the bright sunshine no doubt accentuated by the open aspect and an array of gleaming aircraft. A light NNE wind is drifting across the airfield at this time. At Royston a maximum temperature of 21.1°C was recorded that day, whilst sunshine was logged at a very respectable 15.5 hours.  After the countryside around Royston in May was adorned with swathes of bright yellow oilseed rape, this field of poppies on the Burloes estate close to Eagle Tavern 1.5 km SE of Royston is attempting to keep the theme of bright colour going, as seen in this picture taken at 0838 GMT on 20th June 2006. The poppy seeds have probably remained dormant in this field for some years before being disturbed and springing to life. A westerly breeze of mean speed 5 knots gusting to 12 knots is ruffling the poppies at this time, in a temperature of 18.6°C. After an overnight minimum temperature of 13.7°C a maximum temperature for the day of 23.8°C was later achieved. Daily sunshine of 9.1 hours was recorded, in what ultimately proved to be the sunniest month of any name in at least the last 9 years. On 27th June 2006 a group of mathematics students from Linton Village College, Cambridgeshire visited Royston (Iceni) Weather Station in connection with a data project (linked to the global warming issue) they are working on. The students and teaching staff (pictured above around the station Stevenson Screen) inspected the manual and automatic meteorological instruments in use, the methods used for communication between the automatic instruments and the remote dataloggers, and the dataloggers  themselves. They were also able to observe on screen displays of the live data being received. Sunshine was at a premium on 27th with only 3.5 hours sunshine being recorded, but luckily some of this coincided with the students' visit. The temperature at the time of this photograph was 19.0°C.
