BARREL Kiruna campaign update

Hej (Swedish for hi)

The campaign is almost here! Once again this year we'll have daily e-mails and telecoms during the campaign for coordination between us, the Van Allen Probes, and other friends. The list of friends is continually growing. Some of the new missions we're excited to work with are MMS, HiT&MIS (an Auroral Imager from UMass Lowell), and the new and improved FIREBIRD.

A more complete update on the science side of running the campaign can be found on the science blog here. We'll be putting the daily e-mail summaries up on the science blog as well.

Stay tuned for more updates as the team travels to Sweden and starts setting up at ESRANGE! Also follow the campaign on twitter @KeV_balloons. @PlasmaNerd on twitter (Alexa) will also be twitting the campaign from Sweden as well.

Hej då (Swedish for goodbye)

Two new BARREL papers just in time for some summer reading.

Looking for something to read for this summer? Well we have something for you. Within the last month we've had two new BARREL papers published.

Lauren Blum et al published another GRL on the January 18 & 19 2013 relativistic electron events. It's a great new look at EMIC waves and when they may be responsible for relativistic electron precipitation.

The second paper is one that we've been working on for a long time. It's on two event time periods, one on the 3rd and the other on the 6th of January 2014. For each event we had some fantastic conjunctions between the array of BARREL balloons and the two Van Allen Probes. We were able to show that the plasmapsheric hiss, and then the precipitation where the hiss was resonant with radiation belt particles, was coherent across large regions of the plasmasphere.

Okay so perhaps this isn't really the light summer reading that you were hoping for, but we hope you enjoy them any way!

The Daily e-mails for this year's campaign

Hi all,

As with the previous campaigns, we'll be having our daily e-mails. I'll also be putting up a shortened version here on the blog. I've heard from some of the teams already that they would like to be included, but please feel free to let me know if you would also like to be added to the list. Just leave a comment below.

Thanks and here's hoping for an exciting campaign!

Update on Campaign 3

This year's campaign is starting to come together. We'll be shipping everything off in mid July so only a month and a bit to get all of it put together.

Unlike the previous two campaigns, we'll be flying in the northern hemisphere during turn around. It's a period when the stratospheric winds are changing directions so the balloons should hopefully stay relatively close by. This will make it easy to predict where conjunctions will be with nearby ground stations and satellites. Hopefully it will also make it easy to collect the payloads once they have been terminated! That means we could have multiple flights per payload. It also means that we could still have payloads to fly again next year *fingers crossed*. 

Like the previous campaigns we'll be coordinating bursting with the Van Allen Probes. We'll again have daily e-mails and daily telecoms, but this time it might have to be via google hangouts. (Just a heads up for those interested). If you have an instrument that you would like to coordinate with BARREL please let us know. 

We've also got a new and exciting lineup of other instrument teams who we'll be working with. Over the next few weeks we'll try to highlight the different groups. Each of the new groups will give us a new look at a new piece of the puzzle, just as the Van Allen Probes have. This year has the promise of being a tour de force of measurements!

Stay tuned!

New Publications out!

Long time no post.

The third campaign is really heating up! We hope to have an exciting set of new collaborations just by virtu of launching in a new location, ESRANGE in Kiruna Sweden. (Congrats Sweden on the Eurovision win!)

However, we've also just had a set of papers all come out over the last six months that should be highlighted. 

All of the BARREL papers can be found in the recent publications page. If you notice that we're missing one, let us know and we'll add it. 

There are many more papers on the way so keep a look out and we'll keep you posted. Remember to also follow us on twitter at @KeV_balloons for the latest updates.

From the Ice: BARREL Status Update #43

Hi folks,

 Sorry for the late report, but we had no internet all day yesterday (planned outage). There isn't too much new. Both SANAE and Halley are waiting for surface weather to improve. SANAE has a possible launch opportunity Friday. Halley has a possible opportunity Sunday. If neither of these days are favorable, we may end up not launching since we are leaving soon and have to start packing!

From the Ice: BARREL Status Update # 42

No launches again today due to high surface winds. Payload 2A was terminated at 1730 UT.  For those of you who haven't seen it, here's a link to an article about BARREL on the NASA website. There is also a video that Alexa put together. I can't view it myself but have heard it's great!

Also, some of you have been asking about our travel plans. Our SANAE team leaves around February 9th. They'll fly to Novo and then on to Cape Town from there. The Halley team will board the ship somewhere between February 17 - 20 and will sail to the Falkland Islands. We expect to depart from the Falklands on March 1st to return via South America. As such, the last possible launch date for the SANAE team is February 9th and the Halley team a few days later (we have to have our cargo on the line by February 15th at the latest). Although we've now launched 20 balloons, we'd very much like to replace the two that came down shortly after launch. So, each team hopes to be able to launch one more before departing. So far, surface conditions do not look great for the next few days. We have a possible launch opportunity from both stations tomorrow.
