Messenger No. 16 published
The 2025 February issue of Messenger (No. 16), the newsletter of the Mercury and Venus Section is now published online and available to BAA members. This issue’s contents include an article by Bill Leatherbarrow discussing his 1964 observations of low-contrast features in Venus’ clouds which Hedley Robinson persuaded him to publish in the Journal. These were consistent with the, now accepted, four day circulation of the upper atmosphere of the planet.
