Almost exactly one year after Bishop's ring was observed in Hungary, there's Saharan sand above us in the atmosphere again. The corona with bluish inner and broader ocre outer rings was first noticable on 27th May, but it got really distinct on the 28th. The following day it got weaker, but today it's well-visible around Budapest, again. Meanwhile, the sand has drifted all the way up to the coast of Norway and yesterday there was sandy yellow rain in Germany.
Pale sunset on 28 May and a similar sunrise from the 30th.
