Going home

What happened?? All of a sudden the days just started flying by and the next second, I'm packing my bag to go home again! I definitely didn't sleep away my time, we just realised that within the last 60 hours we've slept 8 hours in total... It was a long day today, starting last night with really really good aurora! Unfortunately it wasn't our radar run, but we were up in the science building anyway and got some great data! I was determined not to go to sleep until the camera boxes had been shipped off to Tromso and Stockholm again with FedEx today, but it was a bit trickier than I thought (I don't think I've ever filled in so many forms in my life!) so that's why we didn't get some rest until 5 o'clock this afternoon! At one point during the form signing, Tobbe just decided a corner in the FedEx office was a good enough place to take a nap, which was fair enough, since I didn't manage very well to stay awake in the car when spending hours trying to find the place. Oh well, now we have 4 hours of sleep before heading to the airport, I think we will both be snoring our way over the Atlantic tomorrow.

So, as a last note from my stay in Alaska, I'm putting out a photo from the Dalton Highway (the road up to Toolik) showing the true Alaskan nature, and another one of the aurora we saw last night... It was really pretty! I'm going to miss gazing out for aurora every night, but I'm really looking forward to getting to sleep during the nights again. And I hope I'll be back in Fairbanks soon again!

Rocket launch!

So the last night of the February rocket window passed with a substorm and brilliant aurora... but no rocket since we were even worse out for winds than we've been before! That means that we will leave Toolik and Alaska without a rocket launch! =( The devastation was total! So total, that we decided we couldn't have it like that, we needed a rocket! So, as Faye would say, what is a girl to do? Well, we needed to build our own rocket! We told Scott and Shelby about our plans, and they had lots of ideas! Shelby turned out to be a top-class producer of hydrogen gas, and Scott is very handy, so they quickly turned a toilet-paper-roll and some tape into our own Toolik Hydrogen Rocket. The rocket was then placed in a tube, with hydrogen gas underneath, that we were going to ignite with a long pokey stick! It was quite windy outside but we decided we were NOT out for winds, and survaillance said GO so we went...5-4-3-2-1 and BOOM! The rocket flew through the air... almost a whole meter!! We were laughing so hard, rocket launches are so much fun, and after having waited for 4 weeks up here it felt so great to finally get a rocket in the air!

After some sequence tests we decided that the Toolik Hydrogen Rocket was ready for launch!


And it went! Just not so far...
So, I know you're all dying to hear if we got any good data? Well, the aurora wasn't so impressive tonight, but two nights ago we had a proper substorm, the whole sky lit up by the aurora and there were so much structure in there! We were standing outside for ages, just gazing up at the sky and all the beautiful forms showing up there... I don't know if you're getting fed up of aurora pictures here, but I can never get enough, so here are some more!

With the rocket window being closed now, we're heading back down to Fairbanks on Saturday, for the third part of this adventure (the first one being working on SMILE at Poker flat and the second up here at Toolik). The last part will be our PFISR radar campaign, when we will try to get some black aurora in our cameras.. We have radar runs almost every night next week, from 22 to 04, so we might as well just stay on a night schedule until we go home.. and we are going home! It's now settled that we are both going back to Stockholm on 15 March. So we're about to start our last week in Alaska, which feels good.. and still, somehow, I really like it here and a part of me could stay forever.

Sweet aurora!

Last night of the rocket window... and we're out for winds again!! This is so frustrating. We're having nice aurora in our cameras at the moment, and they can't launch any rockets... well, all we can do is continue observing it, and collecting optical data. I was out last night collecting some optical data myself, the aurora was amazing, and I got my first photos of coronal aurora... and I saw blue aurora! I'm posting some of my photos here, so you can see. I think we got some really good data last night, we were pointing toward Kaktovik where Hans and Allison are making measurements with their cameras of some 'whimpy minibreakups' that must be something not a lot of people have studied before! Well, when looking overhead we got more dynamic stuff. It was a Themis conjunction night too, which means this data will be very valuable since there's also satellite and radar data for it.

This is what Kristina calls Sweet aurora! I agree!

Well, I can definitely see some blue stuff in there...

Are those two separate arcs?? Is that black aurora?? This is quite an interesting event!
Today we needed a break again, and went out and helped Scott bring logs to the sauna. The great thing about carrying lots of wood down there is that we got to play with the snow machines again! We took a ride over the lake afterwards and it's soo much fun flying over the snow piles! Here's a photo of the sauna (the view through the window is soo nice when sitting in the heat in there):

Tobbe, getting logs from the sled to bring into the sauna. It was a gorgeous day today!
Well, the last night of the rocket window for this period (the next window starts again 15 March, but I don't know yet if I will be around for that or not) is not over yet, and the winds can still change. Could everyone please do an aurora and wind dance for us, we need some help to get this rocket in the air tonight!

Snow blizzard

Yesterday we experienced a proper snow blizzard.. we had winds of 60 mph (28 m/s for all Europeans and other sensible people) and snow, the whole building was shaking and we had to spend a couple of hours closing up the window again that blew open! I've made it into a habit to go outside every hour to check on the weather and aurora, for our updates from here to the rocket people down at Poker Flat, but yesterday I just turned in the door, it was impossible to even step outside. So we spent the evening monitoring the rocket progress without being able to take part much, and then watching 'North to Alaska', an old John Wayne movie from 196o - a film where men are fist-fighting rough heroes and women are deceptive and silly (oh, and beautiful obviously)... Not the best film I ever saw, but I've been humming on the theme song ever since!

Today we had to face the consequences after the blizzard... Our boxes had been filled with snow, even though they were covered up, and then the snow melted since we have heaters inside them... so when we opened the guppy box today there was 2 cm of water on the bottom! We spent the rest of the evening taking things inside and getting everything dry again (we managed to fix a broken transformer to the mount by applying some female touch.. that is, using the hairdryer!) and in the end everything worked, hurrah! The time really does pass quickly although we are just waiting. But doing anything up here takes 3 times as long.. For example, all the work on pointing the boxes in the right position was useless, since the blizzard had blown them down anyway today! So just to start over... I have no photos to put out here from the blizzard, it's kind of hard to catch on camera, and Tobbe wouldn't let me take a photo of him using the hairdryer on the transformer PCA... But I do have a photo of the boxes with some aurora that I took two nights ago. That night we had brilliant aurora, and we kept observing lots of black aurora and other sweet things until the sun came up again.. Unfortunately they couldn't launch the rocket that night either, they were out for winds (it was too windy in the atmosphere for the rocket).

From left to right: Alvis, guppies, Blvis, house. From top to bottom: Sweet aurora, fainter arc in the distance, our boxes with cameras.

So, we are still here, still waiting. We've rebooked our flights so right now we have tickets to come home on 15 March.. Let's see if that is realistic or not!
