Mother-of-Pearl clouds...

...or Nacreous clouds, or Polar stratospheric clouds.
Breakfast was unusually large today, a sort of traditional Swedish Christmas/New Year breakfast consisting of pickled herring, potatoes, salmon, crackers, bread, sauces, cheese, and the tiniest taste of schnapps! A bit different to the more normal muesli and yoghurt, but providing a good start for a traditional day of hard labour in the forest.
However, there was no forest work for us. Shortly after breakfast, at luchtime, we visited Ruth and family, where there was rhubarb crumble and ice-cream on offer. It was particularly lovely to see Ruth who has recently arrived home from hospital after suffering a sort of stroke just before Christmas. She seemed her normal self but gets tired very quickly, as the brain works hard reforming neural networks to replace the damaged ones. We exchanged Christmas presents with the family and had a giggle when we had given them mugs and they gave us mugs.
As we left Ruth's these luminous, multicoloured clouds were in the sky. They are supposed to be very unusual but we see them a few times every winter. They are very high in the sky (20 kms up) and very cold (-80°C), and most visible just after sunset, or just before sunrise.
There was a flurry of photographs from three of us and then we went on our way.
Jan and I took a quick tour of some shops looking for post Christmas sales of cheese, ham and other goodies. No specially cheap cheese, and no cheap organic ham, but in the final they were selling off their Christmas beer. This is our favourite beer, very tasty and only 3,5% alcohol so we fetched a trolley and loaded up.
Fortunately our huge breakfast and subsequent food gave us strength to carry all this beer from the car to the cellar. If you have seen HarlingDarling's blip you'll have seen our beer stash in the cellar. Enough to last us to next Christmas if we aren't greedy!
