Ha Full Disk - 5th April

It was a case of look carefully on the sun on 5th April.  At first sign there is nothing happening, but look closer and there are a number of very small filaments all over the face of the sun.  The clouds of cool plasma are held aloft above the suns surface by magnetic fields.  Proms were in a small scale and also short supply.  Taken with the double stacked Lunt 50 and the PGR Chameleon 3 camera.
