Mars in 2016-'17: Third interim report

摘要

Since the second report on the 2016 opposition in the 2016 August Journal (126(4), 205-206 (2016)), Mars was kept under continuous observation by over 80 observers. This third and final report was prepared just before the solar conjunction on 2017 Jul 27. The apparition had begun with an observation on 2015 Aug 29 at Ls= 034°. The final image was submitted on 2017 Apr 7 by Martin Lewis (UK) and the final drawing by Gianluigi Adamoli (Italy) on May 16 at Ls= 006°. The data covered fully 92% of a martian year.
