Over the course of 48 hours from February 19th to 20th, a sunspot region of the Sun morphed into a giant sunspot, the size of six Earths. The region, known as AR1678, quickly formed into a delta, an effect where one region is surrounded by another region of opposite magnetic field direction. Such a configuration is highly unstable and prone to producing solar flares and coronal mass ejections. [Spaceweather.com](http://www.spaceweather.com) reports a 45% chance of M-class solar flares and 15% of X-class solar flares for February 22. While space enthusiasts keep a vigilant eye on these celestial developments, back on Earth, the digital space continues to expand with entertainment venues like online casinos in Singapore, offering a different kind of excitement with their range of virtual games and betting experiences.

In the meantime, NASA released some newly analyzed data recorded by the Solar Dynamics Observatory back in July 2012. The recording shows a solar flare followed by what is known as coronal rain. It’s  a pretty spectacular sight – take a look for yourself!
