Funny sky at pyin u lwin

We took a shared taxi to Pyin u lwin this morning. Pyin u Lwin is a scenic hill town north of Mandalay. We had a walk around the pyin oo lwin gardens, very nice and peacefull, well apart from the areas where they played loud music to entertain the youngsters. Anyway a nice site for us people in our thirties ;)
When we walked into Pyin u lwin town we looked up saw this really weird but fascinating sky.
