Seeing was particularly bad this night, but I took these images as they were the
closest I could get to opposition. Cloud interfered constantly.
Despite the blurred images there is some evidence of the coherent-backscattering
ring-brightening (sometimes incorrectly called the Seeliger Effect) notable in
the blue image, where the rings are brighter compared to the globe than they are
normally (compared, for example, to my Jan 31 images).
