Rough Legged Buzzard?

Just a quick question to ascertain whether I may well have seen a rough-legged buzzard in a farmer's field near Edderthorpe (nr Darfield) today? I'm fairly new to birding but am aware that these are relatively rare (especially away from the extreme West - Spurn etc). I did get a fairly good look at it through binoculars (10-15 seconds) and the colours, facial markings, and 'rough' legs match the pictures that I have accessed on-line today. Anyone else seen/know of it or have I more likely seen a common buzzard with distinctive markings? Thanks
