The good work by Clyde Foster, ASSA Planetary Specialist, has been recognised again. He was included as a co-author in a paper accepted for publication in Astronomy & Astrophysics.

From the abstract: “First identified in 2016 by JAXA’s Akatsuki mission, the discontinuity/disruption is a recurrent wave observed to propagate during decades at the deeper clouds of Venus… Taking advantage of the campaign of ground-based observations undertaken in coordination with the Akatsuki mission since December 2021 until July 2022, we aimed to undertake the longest uninterrupted monitoring of the cloud discontinuity up to date to obtain a pioneering long-term characterization of its main properties and better constrain its recurrence and lifetime. The dayside upper, middle and nightside lower clouds were studied with images with suitable filters acquired by Akatsuki/UVI, amateur observers and NASA’s IRTF/SpeX, respectively…”
