A group of golfers greeted the easing of England's coronavirus restrictions by hitting the fairways just after midnight.
Seven teams used glow-in-the-dark balls and floodlit greens at the Morley Hayes Golf Club, near Derby, with their opening drives coming at 12.01am.
Golf is among the outdoor activities that can now take place in England, with courses allowed to reopen along with football and cricket pitches, tennis and basketball courts, and outdoor swimming pools.
The seven-hole tournament was held to raise funds for the Nottingham Breast Cancer Research Centre.
Andrew Allsop, managing director of Morley Hayes Golf Club, told the PA news agency the idea for the nocturnal tee-off was made "on a whim".
He said: "It filled instantly, there was so much interest ... we obviously want to try and get in the records that we're the first ones to reopen.
"I think the buzz has been made even buzzier because it's such great weather forecast this week. We've been shut six months out of 12 so it's been very difficult but we'll survive and good times are ahead."

Groups of up to six, or two households, can socialise in parks and gardens once more in England from today, while outdoor sports facilities can reopen.
Restrictions were eased as official figures showed more than 30 million people in the UK have received a first vaccine dose, accounting for about 57% of all adults.
Football and cricket pitches, tennis and basketball courts, outdoor swimming pools, golf courses and sailing clubs are now free to reopen after months of being shuttered.
Organised team sports can also resume outdoors, meaning grassroots competitions can take place ahead of the Easter break without the need for social distancing.
Glenn Earlam, chief executive of gym chain David Lloyd, which reopens 79 of its clubs in England today, said people were "just desperate to get out of their houses and go and do something different".
He told BBC Radio 4's Today programme: "It's the majority of the UK clubs and it's the outdoor facilities, so it's outdoor swimming pools, outdoor tennis and what we call group exercise which is if you want to do a spin class or yoga or anything like that.
"All of those facilities will be open, but in big marquees, so we'll have big marquees outside the clubs in the grounds and the sides of those marquees will be open to let the air come through, but you'll be covered in case it chucks it down with rain."
Johnson urges caution as restrictions ease
British Prime Minister Boris Johnson has appealed to the public to exercise caution as lockdown restrictions in England are eased.
At a Downing Street press conference, Mr Johnson acknowledged it had been a "big day" for many people as they were able to see friends and family outdoors for the first time since the latest controls were imposed.
However, he said it was still not clear how "robust" the defences provided by the vaccination programme would prove if the rise in infections on the continent was repeated in the UK.
"What we don't know is exactly how strong our fortifications now are, how robust our defences are against another wave," he said.
"We have seen what is happening with our European friends. Historically, at least there has been a time lag and then we have had a wave ourselves.
"That's why I stress the importance of everybody maintaining the discipline people have shown for so long."
His warning was echoed by the chief medical officer from England, Professor Chris Whitty, who said there was a "high likelihood" cases would rise as lockdown restrictions were steadily lifted according to the timetable set out in the government's road map.
He said that while most of those at the greatest risk of death or serious illness, had now received the vaccine, the disease spread most rapidly among younger age groups who had yet to receive the jab.
There were already signs of an increase in infections among children of school-age following the reopening of schools in England earlier this month.
However, Professor Whitty said the impact should be "modest" if people continue to follow social-distancing guidelines.
"Yes, there is a high likelihood that there will be some uptick as a result of the relaxations today, and that was anticipated right from the beginning of trying to lay out where the road map would go," he said.
"But if people stick to social distancing rules and they are outside, the risk of transmission is massively lower than if they are very close together and inside.
"Provided people stick to outdoors and at a distance if it's people who are not in their households, the impact in terms of an uptick should be modest.
"I think it would not be realistic to think there will be no impact, and that is something we are all aware of."
