Royal Air Maroc 747-400 visits Brussels, but don't know when.

Amadeus.net , and RAM’s website both say that at 08.35, RAM’s sole 747-400 will depart to Oujda from Brussels, arriving there at 9.20. This flight is carried out at a weekly base. Brussels’ spotting facilities for departurs don’t mean much, therefore I need to know when it arrives and from where. It doesn’t arrive from Oujda. I have checked other possibiliteis like Tanger and Casablanca, but none show a departure carried out by a 747-400 to Brussels. Maroc doesn’t seem a country to me that has night curfews at its airports, so it probably departs around 02.00 somewhere in Maroc and arrives in Brussels just after 07.00, when the big traffic flow starts. 747’s are rare at Brussels, but 747’s landing on 25L (passengers) are even rarer.
Do you have any ideas where it could come from?
