My mistake of using no filter in fotographing sun eclypse with a digit camera (Casio) resulted in pictures with no shadow onto the sun. A strange cylinder appeared instead,with a diameter many times its height. The cylinder showed a larger and very thin disk as a base. In picture 1 the object was at the S/W of the sun whereas in picture 2 at the South.Time elapsed between pictures was about 12 minutes.Pictures taken the day after under an identical set of conditions showed no strange objects.
