Green Flash

The green flash is a rare, fascinating sunset phenomenon. It may be observed when the Sun sinks into the sea. The last shard of the Sun disk turns green for a second or less, before it disappears. Mr. Aymen Ibrahem, BA Senior Astronomy Specialist, made a recent observation of the green flash effect in Alexandria.
The green flash can often be observed when the western horizon is clear. There are several types of the green flash effect. Sometimes a blue flash may also be observed. Ibrahem has photographed several green flashes since November 2005.
