Venus Image 2007/02/26(UT)

This is a digest of my Venus observations for February.
This is not a very consistent set, as, while the UV images are all with the same
filter, the lower line uses different IR area filters. Also, there is a change
of telescope (and scale) for the Feb. 26 images. The Feb 06 IR looks
badly-processed (turned out too small), but unfortunately I have deleted the AVI
file so I can't go over it again.
It will be seen that during February, the bright polar caps were prominent in
UV. The most interesting images are Feb. 21, which show features in IR-R
distinct from the UV features. I have turned this data into an enlarged false
colour image, in a separate file, for what it is worth.
