Jupiter’s Great Red Spot Galileo Anniversary Mosaic 1, natural color
3x2 'anniversary image mosaic' of the Great Red Spot (GRS) that Galileo obtained during its first orbit of Jupiter on June 26, 1996 from a distance of 1.8 million kilometers. The image represents approximately true color and contrast.
This image is based on data obtained through two filters, a 756 nm near infrared filter and a violet filter. In this image, color and contrast have been exaggerated to enhance the visibility of various features and the image has been processed with an unsharp mask to more clearly show small scale features. An enhanced color and contrast version can be found here.
The image shows the GRS from the spacecraft's vantage point, i.e. it is not map projected. The viewing geometry is shown below.
