Aurora Watercolours Perhaps

Today with only one student able to attend class we got talking about how sections of our abstracted landscapes with intense colour (watercolours) remind us of auroras. I commented to her that for sometime I have been contemplating this… only problem is that I have no resource photos of my own. Tonight perusing Twitter this jumped out at me! I do not copy photos per se, so maybe I could use "net" ones (and acknowledge source). Otherwise I can just make something up. That is what happens once I get absorbed in the watercolour "happening" anyway. Will keep you informed.
