Ruth Quist.. One way to determine if what you see is Asperitas is to look at it upside down. The up drafts and rolling clouds are a lot more apparent. The darker clouds in your photo suggest they are lower than the brite alto-cumulus in upper center. Its my experience that lower cloud gets aspirated or demonstrates the phenomena. Therefore i think your photo captures the asperitas phenomena. Its perhaps a thinner show of it but the characteristics are there.
Below is shot that too, is not of a clear and easy Asperitas event. This shot is of small area off from a more serious Asperitas event . Still I think its Asperitas with some of the slightest of characteristics.
