What Would Cause A Triple Sunrise?

How can the same Sun rise three times? Last month on Friday, 2009 July 10, a spectacular triple sunrise was photographed at about 4:30 am over Gdansk Bay in Gdansk, Poland.

Clearly, our Sun rises only once. Some optical effect is creating at least two mirages of the Sun — but which effect? In the vast majority of similarly reported cases, mirages of the brightest object in the frame can be traced to reflections internal to the camera taking the images. Still, the above image is intriguing because a sincere photographer claims the effect was visible to the unaided eye, and because the photographer took several other frames that show variants of the same effect (see below). Therefore, readers are invited to debate whether the above image captures a particularly spectacular example of common reflections inside a standard digital camera, shows one of the most spectacular examples of atmospheric lensing yet recorded, or was caused by something completely different. If the discussion converges, the consensus will be posted here at a later date.

All I can think of is that a cold front was moving left to right in the picture and had just passed line between the photographer and the rising sun.

The current thought is that this has been taken through a double glazed window, hence the double reflection (the "primary" sun, a reflection, and a reflection of the reflection).

This also explains why it would have been visible to the naked eye.

Note the same lens blur at the bottom of the sun and its reflections. This could only have been done close to the observer. If the effect was done in the atmosphere it wouldn't have this copied lens blur.

a reflection is visible in the lower left corner of the 2nd image from the top, indicating the photo is taken through at least one glass window
