An orange (red), green and near-UV colour filter composite image of Mars; the UV channel (the blue color) has been enhanced. The enhanced UV signal clearly shows the presence of the cloud system covering most of the Martian disk.
The image was acquired on 24 February at 19:28 CET from a distance of about 240 000 km; image resolution is about 5 km/pixel. Higher resolution images of Mars will be made available later.
