This is the new 'Greenwich Meridian' sign in Newmarket Road, Royston on the ascent to Hyde Hill to the east of the town. The new sign has replaced a similar one which had stood on the site for many years but which had been damaged. The Greenwich Meridian (0° Longitude) itself just clips the eastern fringes of Royston, so the town itself is positioned just inside the Western Hemisphere. Just 5 km to the south of this point the land rises to over 150 metres on the East Anglian Heights, and following the meridian northwards from this location there is no higher ground all the way to the North Pole, a distance of 4233 km! Additionally, the town of Royston lies just inside Hertfordshire on the Hertfordshire/Cambridgeshire county line so can be classed as a true 'border' town! On 22nd June 2008 the Royston Allotments & Gardens Association held its annual outing, this year to Houghton Hall in Norfolk (approximately 100 km NNE of Royston). As well as the magnificent stately home pictured above (on the day), the estate includes a renovated 5 acre walled garden, park, church, stables and museum. The park is populated by 1000 head of deer, which owe their rare white colour to the way they have been managed over the last 70 years. Clear air and bright sunshine was accompanied by a very strong (for a Summer month) wind, and a small branch which has blown a considerable distance can be seen on the grass to the right of the picture. A maximum wind gust speed of 41 mph was recorded at Royston on this day (sunshine 12.8 hours). This narrow band of cloud drifted slowly eastwards over Royston in the morning of 26th June 2008 and was here pictured from the Burloes estate close to the B1039 Royston to Saffron Walden road at 0804 GMT. This band of cloud was visible on 0800 GMT satellite images and appeared to stretch from the Wash for about 100 km south-westwards. It soon started to diffuse, however, and had disappeared from satellite images by 0900 GMT. The barley crop seen in the picture marks a return of this land to cultivation this year after a period of about 8 years as grassland. A westerly wind of mean speed 9 knots gusting to 16 knots is bending the barley ears in a temperature of 16.8°C. This day was rather breezy with a maximum gust speed of 34 knots recorded (at 1340 GMT).
