\"AR1339\"<\/a><\/p>\n

Active region 1339 is a group of sunspots on the Sun that was discovered a week ago.\u00a0 A sunspot is a spot on the photosphere of the Sun. It appears as a dark spot because it is cooler than the surrounding surface.\u00a0 Cooler does not mean it is cold by no means.\u00a0 A sunspot can reach 4500 kelvin.\u00a0 The Sun reaches about 6000 kelvin.<\/span><\/span><\/p>\n

We have not seen a sunspot region like this since 2005.\u00a0 You can actually see AR 1339 from Earth with the naked eye.\u00a0 That is not entirely true.\u00a0 One should never look directly at the Sun.\u00a0 There are safe ways to view the Sun, and if you intend to look for AR 1339 you should follow these suggestions<\/a>.<\/span><\/span><\/p>\n

AR 1339 is approximately 17 times the width of our planet.\u00a0 There are spots within the cluster that are larger than Earth.\u00a0 We see the Sun everyday and its enormity eludes most of us.\u00a0 You could fit 11,900 Earths inside of the Sun.<\/span><\/span><\/p>\n

A sunspot is caused by intense magnetic activity.\u00a0 This magnetic activity cools certain areas on the sun and cause them to be dark.\u00a0 With intense magnetic activity there are the chances of\u00a0 coronal mass ejections (CME) and solar flares.<\/span><\/span><\/p>\n

Below is a picture that was captured on November 3, 2011 by NASA’s Solar Dynamics Observatory<\/a>.\u00a0 This is a close-up of the X class<\/a> solar flare that erupted from the Sun at 3:27 p.m. ET.<\/span><\/span><\/p>\n

\"SDO<\/a><\/p>\n

This X class solar flare disrupted radio communications on Earth.\u00a0 Thankfully, it was not aimed directly at the Earth.\u00a0 This week AR 1339 will be aimed directly at us.\u00a0 This means that if a solar flare or a CME should erupt they would come straight at the Earth. Relax, the talk among astrophysicists and astronomers is if this should happen the most we will have is a great aurora show.\u00a0 The worst that could happen is it could wipe out some satellites and communication devices.<\/span><\/span><\/p>\n

The Sun has an 11 year cycle.\u00a0 We are nearing the peak of this cycle.\u00a0 At the peak of a solar cycle solar activity is at its highest.\u00a0 The Earth is protected from solar activity by its magnetosphere.<\/span><\/span><\/p>\n

\"Magnetosphere\"<\/a><\/p>\n

In the past 7 days we have had 5 major CME that produced beautiful auroras or “Northern lights”.\u00a0 The light show is a result of electrically charged particles getting trapped inside Earth’s magnetic field.\u00a0 The majority of sun particles that get ejected are deflected by the Earth’s magnetosphere.<\/span><\/span><\/p>\n

\"Aurora\"<\/a><\/p>\n

These are a few websites that I would like to share with you:<\/span><\/span><\/p>\n

\"SOHO<\/a>
\n<\/span><\/span><\/p>\n

The website above is the Solar and Heliospheric Observatory<\/a>.\u00a0 You can view real-time images of the sun.<\/span><\/span><\/p>\n

Space Weather<\/a> (below) is a very informative site that gives you information on the Sun and weather in space.<\/span><\/span><\/p>\n

\"Space<\/a>
\n<\/span><\/span><\/p>\n

There are 2 CME’s that are headed in our direction that are likely to create auroras on the 11th-12th.\u00a0 If you are in the northern hemisphere make sure you look for them!\u00a0 Please, if you witness these auroras I would love for you to comment and tell your story.\u00a0 If you take pictures, please send them to me and hopefully we can get those up on the website to share with everyone.<\/span><\/span><\/p>\n

In closing, I would like to welcome everyone to Wormholeriders new science site.\u00a0 We are very excited about this project as it has been in the works for a few months.\u00a0 We have more features to add to the site.\u00a0 We have an impressive list of contributing writers for this site and we are honored to have them share their knowledge with our readers.<\/span><\/span><\/p>\n

Thank you for reading and I hope to hear from you soon if you have any stories or pictures to share in the event we do get to see some auroras in the upcoming days.<\/span><\/span><\/p>\n
