Many thanks for that explanation. It certainly looks from the streakiness in
the image that it was taken from behind glass, but it appears that I could
be mistaken. It does highlight, however, that details of where and how a
photograph is taken are important, e.g. location, time, exposure, when
trying to identify anything out of the ordinary.

The picture was not taken behind glass or plastic, the phenomenon was just
this bright. In fact, "the ball of light" wasn't even moving, but followed
a
nearby strike and was attached to a light pole with power lines for a
tram.
I think it isn't a "genuine ball lightning", but some sort of burning of
material (Magnesium?) from this pole or power line.

I agree with the posts that attribute the bright patch to reflection in
glass or plastic. From streakiness visible in the image, it is obvious
that
the exposure was made behind glass or transparent plastic, and
reflection
of
flash or some other light source behind the camera is the most likely
explanation.
