Sunset at the South Pole

The past couple of week have had some amazing moments here at the South Pole.  The sun has finally set, and it was beautiful. Unfortunately, the weather hasn't been very cooperative, and the visibility was low, so we weren't able to see much of the sunset, but thankfully, the weather did clear up enough a few times to get some amazing views as the sun dropped below the horizon. One early morning in particular, the clouds and fog cleared up and we were able to get out and take some great pictures... well, mostly Martin.  I am truly impressed with his photography skills, but I did get a couple pictures myself that I really liked.  You can see way more of Martin's pictures on his flickr site (https://www.flickr.com/photos/135762220@N06) or in a small album I have created with a handful of his pictures on Google Photos (https://goo.gl/photos/G2rSrre2hVAQsAtE9).  One thing that I kind of thought that was funny is that we were actually out from 2:30am to 4:30am taking pictures of the sunset. It seemed funny to me to be out at such a time for sunset, but that is one of the unique aspects of being down at the South Pole.  Another interesting effect is the famous green flash actually lasts much longer here.  Martin also got an amazing shot of that, but unfortunately by time I found out it was happening, the flash had ended.

As can be expected, we have special celebrations down here for all the major American holidays, Thanksgiving and Christmas and such, but we also have a few other special events that we do here.  In particular, we actually have a special Sunset Dinner where everyone gathers together and the galley staff goes all out and makes a special meal for everyone. We celebrated our Sunset Dinner this past Sunday evening.  It was an amazing meal.  We had salad using greens and tomatoes from our small greenhouse.  There was bison steak and duck for the main course and a desert of fruit, a truffle, and some creme brulet. Our food is generally pretty good here, albeit not always as fresh as we would like, but during these special dinners, the galley staff goes above and beyond, and they prepare some amazing food. During the event many people on the station volunteer to help set up and clean up during the day so the galley folks can focus on the meal prep.  Martin and I and many others volunteered to help out this time.  I spent a couple hours helping in the dishpit and setting up tables and such.  Martin helped with the table setup and decorations.  After the dinner was finished, there was a small gathering where people got together and just hung out for a while.  It was a great evening.

On the science side of things, the detector has been running very smoothly.  This past week, Martin and I helped with some calibration work that was mostly handled by individuals in the North. On Monday, there was a Dark Sector open house.  The Dark Sector is a region off of the station where we try to minimize radio and other electrical noise for the experiments running out there.  Martin and I gave a tour of the ICL. Given all the activity on station the past few days, not very many people showed up, but it was still fun. We talked about the detector and the science we do, and then we showed everyone around the lab.  Afterwards Martin and I did some winter prep by putting up covers on the windows.  During winter we try to limit the light pollution from the station and the experiments around the station for some of the experiments running here that need it dark.  This means all the windows on station are covered to block any light from getting out.  Only red light is allowed outside, except of course in cases of emergency. This also means that to see the aurora and stars we will have to actually go outside where it is going to be very cold. That should be interesting...

On a more frustrating note, we have been having some issues with our Internet on site. Since we are so isolated from the rest of the world, we rely on satellites to provide Internet and phone communication.  For those curious, no we don't have satellite tv, and definitely no normal cell phone coverage. Our primary means of communication is through these satellites.  There are four satellite systems we access.  One is dedicated to emergency types of communications.  The other three provide access to general phone usage and Internet.  Unfortunately, even at the best of times, these satellites can be a little slow.  Even the fastest is too slow for any serious streaming, and it only lasts for about three hours a day... or it did until it went down a couple weeks ago.  Since then, we have only had the other two of our satellite systems working. One of these lasts for about six hours, but is incredibly slow.  You can load most web pages and use email, but it can take several minutes to do anything.  The last one comes on late at night and lasts for about three hours.  It has speeds somewhere in the middle, but with 46 or so people fighting for bandwidth, even it can get really slow at times, not to mention that it comes up late enough that it makes it hard to use it communicate directly with anyone back home as they are all in bed! I will freely admit that this is a bit of a first world problem, but keep in mind this is our only way to communicate in real time with friends and family, and it can be quite frustrating.  Hopefully, they will fix the problem soon, which as I understand is actually with the satellite dish in Christchurch, NZ.

Besides the Internet issues, things are going fairly well. Now that the sun has set, I am waiting for things to get dark here. We have already seen one bright star, but it will still take a few weeks before it gets dark enough to really see the night sky in all its glory. In the mean time, I am trying to keep focused on work and  my personal projects and enjoy my time here. While I have had a little problem focusing on the projects lately, I can definitely say that work is going well, and I am very happy here. I have been thinking about my time here and talking with others, and I think by the time winter ends and I head home, I will definitely be ready to go, but I know that I am going to miss this amazing and beautiful place with all the amazing people that I am living and working with over this year here. In the mean time, I am going to enjoy the experience while it lasts!

Many of the photos below were relatively recently taken by Martin.  Several were posted to Facebook, and I am reposting them here for those of you who are not friends of Martin or I on Facebook and haven't seen them yet.  He is an amazing photographer!
