Sunset over Chamberí, Madrid

Thank you, Colin.
For about a year or 18 months I saw lots, mainly dawns but the odd sunset too. I used to think it might have been due to volcanic dust in the atmosphere but I realise now that it was simply that I lived for 9 months near the top of a high-rise block of flats and then 9 months at the top of a lower block but with a terrace. So I had the opportunity, that's all!
Now i'm in a nicer flat but low down and looking into an interior courtyard, so no skies of note!
