The marking was carried out with great accuracy and the Main Force bombing was very effective. Crews saw through the clouds a huge explosion on the ground, the glow of which lingered for nearly 10 minutes. This was caused by bombs blowing up the naval ammunition depot at Mariensiel to the south of Wilhelmshaven. The resulting explosion devastated an area of nearly 120 acres and caused widespread damage in the naval dockyard and in the town. Much damage was also caused by other bombs.

Much of this caption is nonsense.
The attached Google Earth photo shows the aiming point in the naval dockyard in the town was 4kms away from the exploding Mariensiel arsenal. The bit of dock shown in your aerial photos is the Westwerft, which was mistaken by the photo interpreters for the naval dockyard.
I told you the raid happened in a NE gale which blew the skymarkers over Mariensiel before the Main Force arrived.
No doubt Butcher Harris put your pictures in his Blue Book together with the misleading caption.
By the way, where are these Blue Books today? Rumour has it there were three copies - one on Harris's desk, one on Churchill's desk, and one in the British Embassy in Moscow for showing to Stalin.
