The image was taken by Alfred Tan in Singapore on April 26 2012 at 10:00 am with a DMK 41AU02.AS camera on a Borg 76mm achromat fitted with a Solarscope SF50mm H-Alpha Single etalon filter. 1,800 selected frames from a 2 minute video were aligned and stacked in Registax 6 and colours added in Photoshop CS3. The DMK camera has not failed to amaze the local astronomy community with clear solar disk details and sharp prominences on the limbs. It is one of my most-used imaging camera and a worthwhile investment.

Beneath the huge prominence is Sunspot 1459 and further after the two filaments is Sunspot 1465. There was excitement on April 25 2012 because Sunspot 1465 has developed a "beta-gamma-delta" magnetic field that harbors energy for X-class solar flares.
