@korina Thank you for this information. It is exactly what I was looking for and perfectly explains the situation.

I did actually look for this information before submitting, but didn't find it. Could I suggest that the "System Status" category be included in the main menu, perhaps beside "Error Console"? I would never have submitted the bug report had that been the case.

@petra-pik Is there any timescale for resolving this problem? I note that detailed satellite imagery is available for Europe; I have attached a comparison with Sat24.com.

@petra-pik Thanks for the explanation.

@petra-pik I have added a screenshot showing the transition from high quality imagery in the Atlantic to poor quality imagery in Europe:

Hope this helps...

The resolution of the European satellite view has recently become very poor in the visible and blue channels. In fact, they look identical to the infra-red channel (which is always fairly low resolution).
