Jungles,

to IIS too!

I've had a look this morning at the images from the live feed. No, it's not the Moon. You are right. My mistake.

There are now a couple of reflection flares and TWO of these spots. I now suspect that the spots are focused reflections from the glare of the sun. I've seen this happen on my photos with unshielded lenses. Focused internal reflections aren't all that common these days with today's multi-coatings, but they do happen. The reflection comes off one (or more) of the internal elements, and itself is reflected back and into focus from the other element members.

Another source of the reflection could be the unblackened metal housing.

I'm not surprised that it's visible in these webcam images as these cameras normally are made very cheaply and with minimal, if any, coatings on the lenses.

It may or may not have the focused reflection move relative to the movement of the sun. But that it is focused may only see the spot appear fixed to the one spot.

HOWEVER, a third reflection source just occured to me that it could be the housing that the camera is placed in, particularly if it is a dome. The inside of the dome could be reflecting the light within the housing back into the lens. Then, regardless of the camera quality, it may well be inevitable to get this artefact appear. I've also remembered seeing these spots on images on CCD external security cameras that face the direction of the Sun.

If its not a reflection, then I am affraid that it IS a UFO, and the buggers are looking to trigger off a major eruption, . Better nuke them, just in case.
