Well, after the "no uploads" problem and the frustration of having to use the original tiny copies for old images I was bringing forward, I decided it was time to replace a few. That was when I found the latest "bug" - it's possible to upload but at present the system cannot handle replacements - the new image won't connect to the old. So, as a workaround, I've included the old (2012) version as a clickable PiP to preserve the original comments etc. Apart from the year, the date is meaningless. :-)

Mawson lies under the auroral oval, the annular zone around the south magnetic pole where auroras are most prevalent. In plain language, there was an aurora most nights. They were so commonplace that, when someone entered a building and said there was an aurora outside, the usual question was "is it a good one?" before anyone would consider going out to look! This is from one of the Ektachrome films we "home developed" while there, hence a little grit.
