STARGAZERS rejoice - a little-known York observatory could open to the public seven days a week for the first time in its history.

The historic Museum Gardens facility is in full working order, but only usually open its doors for a couple of weeks a year.

But now the York Museums Trust, which looks after the "hidden treasure" observatory, has launched a volunteer recruitment drive with the ultimate aim of opening the building every single day, starting this summer.

Fiona Burton, volunteers manager for the Trust, said: "Thousands of people walk past the observatory every year and many are intrigued by what it is and why it is there. Our aim is to recruit about 20 to 30 volunteers of all ages and all backgrounds to bring this hidden treasure of York to life all year round."

Two volunteers will be in the observatory at all times, with the shifts split into half days. Four people have already been recruited and it is hoped more will come forward in the coming weeks, with training taking place at the end of May.

Camilla Nichol, the curator leading the project, said: "This is the perfect opportunity for a wide range of people - from those who want to put it on their CV to people who have some spare time to learn about this fascinating building.

"People interested should get in touch so we can have an informal chat and then provide them with the training they need."

Among the observatory's hidden secrets is clock made by Barraud of London in 1811, which tells the time based on observations of the positions of stars. It was once the clock by which all others in York were set and is still always four minutes, 20 seconds, behind Greenwich Mean Time.

In the middle of the 19th century it was the most accurate timepiece in York and, unless you were a member of the Yorkshire Philosophical Society, it would cost sixpence to check a timepiece against the Observatory Clock.

l The Trust is looking for people willing to spare at least half a day a week for work at the observatory. No previous experience or knowledge of astronomy is needed, as full training will be given by curator of astronomy, Martin Lunn.

All that is required is that people are over 18 and have an interest and enthusiasm for history, astronomy or science. Their job will be to interpret the items on show, such as the telescope, and inform people of the history of the building.
