    Description

    Venus under excellent seeing on 01-Jun-23.

    Thanks to the conditions, particularly fine cloud structure was visible in the ultra-violet band, with the bright polar hoods also nicely resolved. The Schröter effect is also very noticeable in this image with Venus appearing much less illuminated than the actual (expected) phase.
