Tickets for next year's Glastonbury music festival sold out in less than 24 hours.
People who registered with organisers were able to buy a ticket from 9am yesterday morning.
A statement on the festival website today read: "Tickets for Glastonbury 2010 went on sale at 9am this morning (Sunday 4 October) and the festival's 40th anniversary is now sold out.
"Thank you to all those who bought tickets. Confirmation emails are still in the process of being sent out.
"For those who didn't manage to reserve or buy tickets today (Sunday), there will be a small number of tickets on sale over the coming weeks when any failed transactions have been cancelled.
"For anyone who is not already registered, registration will reopen at 9am tomorrow (Monday 5 October) at www.glastonburyregistration.co.uk ."
Next year is the 40th anniversary of the event, which is held at Worth Farm in Somerset.
This year's festival attracted 137,000 music fans and featured acts such as Blur, Neil Young and Bruce Springsteen. It was hailed as one of the best by festival-goers and organisers alike.
Co-organiser Michael Eavis said of the 2010 event: "The expectations are really high.
"We're trying to get the best headliners in the world."
The event takes place between June 23 and June 27. Full weekend tickets cost £185 - up £10 from last year - plus a £5 booking fee.
The registration system, which does not guarantee a ticket, was introduced in 2007 to combat touting.
Last year fans were able to extend their registration for three years.
Anyone unsure whether their previous registration is still valid can check online.
