This observation was intended to be an image of Liu Hsin ejecta, but instead, haze and/or clouds were observed. At this latitude (approximately 50 degrees south), it is not entirely unexpected to get some clouds with the lighting rapidly changing and water-ice frost sublimating into the atmosphere.

Because HiRISE is primarily designed for geologic investigations of the Martian surface, HiRISE planners use images for its sister instrument MARCI to try and avoid bad weather on Mars. But just as on Earth, the weather is sometimes unpredictable.
