  4. Super Moon? How About a Super Sun!

    “On May 5, 2012, while everyone else was waiting for the “Super Moon” astrophotographer Alan Friedman was out capturing this super image of a super Sun from his back yard in Buffalo, NY!

    Taken with a specialized telescope that can image the Sun in hydrogen alpha light, Alan’s photo shows the intricate detail of our home star’s chromosphere — the layer just above its “surface”, or photosphere.

    Prominences can be seen rising up from the Sun’s limb in several places, and long filaments — magnetically-suspended lines of plasma — arch across its face. The “fuzzy” texture is caused by smaller features called spicules and fibrils, which are short-lived spikes of magnetic fields that rapidly rise up from the surface of the Sun.

    On the left side it appears that a prominence may have had just detached from the Sun’s limb, as there’s a faint cloud of material suspended there.”
