Russian race organisers are still not ruling out the possibility Sochi could switch to a night race format in the future.
However, the Russian news agency Tass insists that the 2017 Russian grand prix will definitely be held in the day.
Promoter Sergey Vorobyov confirmed: "There will not be a night grand prix next year, but the idea is still alive."
The three current F1 night races are Singapore, Bahrain and Abu Dhabi.
