Fears Barcelona could be dropped from the 2012 calendar have been eased by the circulation of a new provisional schedule in Hungary.
It was rumoured the Spanish venue might have to alternatively share a single annual calendar spot with Valencia, but both destinations are showing on the latest unofficial schedule.
The only change for Barcelona is a move of its original date by one week.
"Bernie asked us if we were ok with the date change and as we are still the first race in Europe we accepted completely," Circuit de Catalunya chief Salvador Servia is quoted by Diario Sport.
Another change for 2012 is the inaugural US Grand Prix from a hot June date to November, amid rumours the change will also give organisers more time to build the Austin circuit.
"That is provisional until approved by the WC (FIA World Motor Sport Council)," FIA official Nick Craw told the Austin American Statesman by email.
