I remember seeing that same phenomenon in Jerusalem during the summer (IIRC), it looked amazing!
+1 somewhere in July IIRC
we wer all wondering what that is
at least now we know its 'citrus clouds creating a hello'
so next time I see an Israeli confused about it I will just tell him
זה איזשהו הלו מיוצר ע"י ענַנֵי הדר........
