Description
The blue regions indicate the presence of ice in the uppermost surface layer; red shows no ice; and grey indicates portions of the comet that were in shadow.
The animation shows the ice abundance at each time during the comet's 12.4 hour day, such that each data point represents the average, for a particular hour of the comet day, over the entire time period August-February.
