Yesterday was the day of spectacular nacreous clouds.  Nacreous clouds are wispy clouds that form under certain specific conditions (very cold temperatures at very high altitudes) and that can appear iridescent when the angle of the sun is very low, as it is now at Scott Base.  If you do a web search for images of nacreous clouds, many of the images you will see were taken from locations near Scott Base on Ross Island.

For the last week or so, as the sun has come closer to rising, we have been in prime nacreous cloud viewing conditions.  Nearly every day Sarah or Jane says, “go look out the window at the clouds,” and I run over to a window to see what we’re getting.  However, yesterday topped everything we have seen so far, and in fact topped everything most people at Scott Base have ever seen.  Pretty much as soon as a strip of light appeared at the horizon (at a respectable 9:13 a.m.), the Scott Base staff started making cloud announcements over the base-wide p.a. system.  I remember Jana saying at about 10 a.m., “Scott Base, Scott Base, look at the clouds above,” and Steve, at about noon, saying, “Scott Base, Scott Base, if you’re not looking at Erebus right now, you probably should be.”  At around 2 p.m., Sarah, who was supposedly in a meeting at that point, made the announcement: “Scott Base, Scott Base, the clouds are green.”  Before darkness hit at 4:39 p.m., I personally had taken 93 photographs of clouds.

It is just three days until the first flight of the WINFLY season (the pre-main season flights to exchange cargo and personnel ahead of the main season that starts in October). We are expecting a few new faces at Scott Base and about 350 at McMurdo. It will disrupt the everyday routine we have all become used to and will most certainly lead to a few faces that look like an animal caught in the headlights.


It is wonderful to see daylight creep ever further into the sky behind Mount Erebus and there is a noticeable difference in the number of people who sign out at lunch time to go for walks to absorb some Vitamin D! Just the idea of daylight seems to have given people a new energy that has been lacking for some time now.


We are all looking forward to the mail and fresh fruit and vegetables that will come down. Unfortunately, it is the end of the winter season for Antarctic Heritage Trust and we are working hard to get some last minute work completed before our new conservator, John, arrives on Saturday. We celebrated the end of our winter together with a special dinner followed by a performance in the bar by the Scott Base band- sadly, their last performance together as guitarist Julie leaves next week with Sarah and Martin.
