Art, chat and NASA inspired baking

Happy Half-Birthday Solar Stormwatch….part 3

What’s the last thing you would expect when joining a forum? Making some good on-line friends maybe? Or actually meeting up with the people you post with (and finding that they really are OK!)? Or discovering hidden artistic talents? Or (and I think this might win) enjoying the culinary efforts of a lead team member who just happens to have a STEREO spaceship shaped biscuit cutter courtesy of NASA? Grin

Told you that one would win!

As well as a place to discuss the science and ask questions the Solar Stormwatch forum has developed into a place to chat with friends and share a virtual cup of tea or coffee and a slice of virtual cake.

The sense of community is important for some participants. It adds another dimension to taking part in the project. It might not be the busiest forum out there but it is somewhere people can drop in whenever they want advice, information, contact with other stormwatchers or team members or just to chat. Some people prefer to lurk – we always have guests – and that’s fine. In fact the majority of people who take part in Solar Stormwatch don’t use the forum at all, which is not unusual. You tend to find this with many projects. However, forums are not only where interesting discussions take place but where interesting finds pop up. Galaxy Zoo found the Voorwerp. Moon Zoo is looking for Moon bridges and Solar Stormwatch found circular storms. So anyone reading this who hasn’t discovered the forum yet – please consider coming along and joining in. It’s the place where the science team raise issues and ask for our help with extra projects. And the place where that unusual discovery is waiting to be made. Don’t miss out!

One forum thread in particular has something of a cult following. The Sun Art thread has attracted several arty types and the results are spectacular. Here’s just a taste courtesy of algwat, Christelle, Deanimation, Quialiss, Galactic Momma, me and resident artist Caro.

All pictures are based on single frames from Solar Stormwatch videos or related images of the Sun.

Posting on a forum is one thing but what about actually meeting up with people? Other forums do it but many people involved in the Zooniverse projects are new to forums and are naturally wary. It’s quite a big step coming out from behind your avatar and shaking hands but after 3 years of meeting people from forums I can highly recommend it. A small group of us had a Solar Stormwatch meeting back in March 2010 when we hijacked a Solar event at the Royal Observatory Greenwich.

One of the highlights of the meeting was sitting in the Endeavour Room at the top of one of the Observatory buildings at the biggest round table you have ever seen surrounded by old solar and astronomical equipment. Another highlight was these:

Biscuits in the shape of STEREO spacecraft! Never did establish whether it was STEREO A or B! Team member Chris Davis brought them and took an empty container back home. And the biscuit cutter really was from NASA.

We also got caught up in Word Cup fever and had our own World Cup Competition to find the solar storm that looked most like the FIFA World Cup Trophy.

The real thing
The winner! (Herve Stevenin.)

So in 6 short months we have helped collect hundreds of solar storms, found comets, planets, lots of dust, a World Cup trophy look-alike and established a truly international community.

Here’s to the next 6 months!

The First 6 Months: Happy Half-Birthday Solar Stormwatch!

Just 6 short months ago a new Zooniverse project was born. But this one was different. Not a galaxy or supernova in sight. Just one rather special star. Ours.

Solar Stormwatch was set up to track and monitor coronal mass ejections (CMEs) better known as solar storms. There’s a great deal we don’t know about solar storms. We know the Sun isn’t as quiet as it seems and that sometimes, huge solar explosions are hurled out across the solar system. As Chris Davis one of the Solar Stormwatch team says:

“Each one of these storms is a billion tons of material traveling at a million miles an hour, so they’re not inconsequential.”

One thing we do know is that they are spectacular to look at.

In fact they can be seriously spectacular.

There is a downside, however as with each solar storm comes a deadly blast of radiation so astronauts on the ISS need to know if a storm is on its way and which direction it’s heading so they can time their space walks carefully. Solar storms also have the potential to knock out communication satellites, damage power lines and disrupt mobile phone networks as well as produce spectacular auroral displays.

But no-one really knows what triggers them, why they happen or why they are different each time. To find the answers requires analysing thousands of solar storms. Acquiring data isn’t a problem. Since their launch in October 2006 the twin Stereo spacecraft have provided 25 terabytes of data – over 100,000 images. But that’s a lot of data for a small team in deepest darkest Oxfordshire to analyse. Ideally they needed a few thousand research assistants who were happy to offer their time freely and who wouldn’t drink all the team’s coffee and eat all their biscuits so the team turned to the crowdsourcing benefits of Citizen Science and on 22 February 2010 Solar Stormwatch went live.

So what have we found in the first 6 months? The Science Team at Rutherford Appleton are busy collating and analysing the results but in the meantime, while we eagerly wait for them, here’s a summary from a user’s perspective.

1. We have confirmed 229 storms from Solar Stormwatch Spot videos. This will help the team’s research into the speed, direction and frequency of solar storms. Each solar storm must be validated by several stormwatchers to count. The more people who mark a solar storm, the more likely it is that it really is a storm. To trigger further investigation the team need at least 20 people to spot the same solar storm.

2. We have also checked current (“live”) storm data. Around 25 solar storms have been found this way. To do this we use Stereo’s “beacon mode” data. This is a low quality version of the latest pictures transmitted every hour, so we can keep watch on events as they happen. The pictures are black and white, grainy and slightly mysterious but as near to real time as we can get and to see a storm appearing at the end of a video is always exciting. Then there is the wait for an hour or so for the next frame to be added, and then the next….

3. We have learned about circular storms – the “Perfect Storm.” Solar storms come in different shapes and sizes and exactly what kind of storms we see being hurled out from the Sun depends partly on their magnetic fields. The Sun behaves like a liquid which complicates things somewhat and the magnetic field lines that go through the “surface” twist and loop as the conductive fluid moves around. Without any further complications storms tend to end up in a helix shape and appear like a cylinder. If you look at a cylinder end on (the view we get from Stereo) you see a circle, a circular storm – a relatively simple uncomplicated storm. The “perfect” kind of storm to study.

Over 90,000 people have visited the site from 174 countries or principalities. The top 5 countries (ranked in order of highest number of visits) are:

    1. UK (30%)
    2. USA (25%)
    3. Canada (5%)
    4. Germany (3%)
    5. France (3%)

We have just been set a new stormwatching challenge and now we can trace and record individual storms in more detail and later in the year we will learn how to track storms. But Solar Stormwatch is so much more than just watching and measuring storms. In the last 6 months we have found all kinds of weird stuff – caused by camera flares, optical effects, spacecraft rolling manoeuvres and dust. In fact an early Solar Stormwatch discovery was that the Stereo spacecraft are encountering much more dust out there than expected and this has produced some interesting results. Stereo’s eyes have also spotted comets and planets including the Earth and Moon. And we have a real community with competitions, meet-ups, an art gallery and a virtual café with an endless supply of cake. But that’s enough for now. More about those next time.

Meanwhile – if you are reading this and haven’t considered Solar Stormwatch, why not try something a little different? You can do as much or as little as you want. You can choose the task you like best and stick to it or dabble in all of them while you learn about the effect of our nearest star on its neighbourhood. And if you need help just pop into the forum where you’ll get a warm welcome.

Next time: The Particles Strike Back….and other strange happenings.
