Does this photo really tell about the Miracle of the Sun of Fatima?

In 1917, a Fatimain Portugal, three poor children - Lucia, Jacinta and Francesco - claimed to see the Virgin Mary and that he would perform a miracle on October 13, in an open field.

When the day came, there were thousands of people: believers, skeptics, journalists and photographers. The sun began to zigzag across the sky and various bright colors appeared.

Did anyone manage to photograph that phenomenon? Well, there is a photo circulating on the internet and it is this:

The sun is the slightly darker point, located in the central part of the photo, a little to the right.

A main feature of the Miracle of the Sun was that the star was moving, so it would be difficult to capture the exact moment in a photo. So, if it were real, it would already be a historical artifact.

The problem is that the photo was not taken in Fatima in 1917.

Shortly after the event several photos were published but none of the sun. The image covered by this post appeared years later, in 1951, on theObserver Romanor, claiming that it was taken that very day. Later, however, it was discovered that this was a mistake: the photo was from another city in Portugal in 1925.

It is unclear why photos of the crowd were taken during the Miracle of the Sun but not of the sun itself. Was it because the photographers couldn't see (because everyone couldn't)? Or perhaps a photo of the sun has simply never been published?

However, there remain the beautiful testimonies of those who saw that miracle with their own eyes.
