AR 1476 – the monster sunspot
May 17, 2012
The sun is without a doubt our primary benefactor and without it life as we know it would have been utterly impossible. One of the intriguing features of the sun is the sunspot, comparatively cooler region of the photosphere of the sun that harbors intense magnetic activity. Sometimes these sunspots grow to massive sizes and recently I was lucky enough to observe one of these monster-size sunspots, designated AR 1476.
This image of the sun was taken on May 14th 2012 using Celestron NexStar 6 inch telescope with a full aperture solar filter. AR 1476 is the largest of the five sunspots that can be seen prominently in this image.
In 2016, The Planetary Society’s LightSail program will take the technology a step further.
