Fans in Two Directions from one source?

• by jumping_jivey

  This one seems to originate on one point but has two fans. Looks to me like the wind changed direction!

  Absolutely right! Fans could be created at different times, from first to second wind changed to almost opposite.

  The left hand fan has a teardrop shaped feature in it. Convention would put the sun bottom right which would make the feature a depression as the right had side is bright. So if it is a depression why is the whole thing not dark? If it were a lump then no dust on the lee side would make more sense, so where is the sun?

  Yep. Let's try and mark these as #doublefan on Talk. Definitely looks like the wind changed direction by 180 degrees at some point. Nice find.
