Observational alerts issued for NA2 during Reporting Period 1.
The observational alerts issued through PVOL for NA2 were followed by over 200 active observers. The alerts are also sent through the hstjupiter list on groups.io, which has 64 members including highly active astro-photographers. Each of these alerts has generated new observations by observers., i.e.:
31st March 2020: Storm Activity on Saturn’s North Polar Region. Active follow-up by Trevor Barry (Australia), Clyde Foster (South Africa) and Christopher Go (Philippines).
31st May 2020: Jupiter Storm in the South Temperate Belt. Active follow-up by many observers over June-July.
3rd July 2020: Amateur Support to Venus Research. Active follow-up with tens of images by amateur astronomers: J. Camarena (Spain), M. Kardasis (Greece), L. Morrone (Italy).
18th August 2020: New Storm in the North Tropical Zone-North Temperate Belts Jetstream. This was a major event in Jupiter atmospheric dynamics and attracted large interest from the amateur community. Follow-up observations were obtained by several observers with initial coordination from PVOL later, with analysis by multiple active observers from many different countries, resulting in hundreds of observations uploaded into PVOL.
18th September 2020: Jupiter’s North Temperate Belt Plume and Turbulent Wake Interaction. This was a continuation of the previous alert.
13th October 2020: BepiColombo Flyby of Venus: Request for observations. Active follow-up by amateur astronomers: J. Camarena (Spain), M. Kardasis (Greece), L. Morrone (Italy).
29th July 2020: The possible detection of a volcanic plume at Io by J.-L. Dauvergne (France) could, If proven true, be the first detection of a volcanic plume in Io from ground-based observations although hot volcanic spots are regularly detected with large (8-m) telescopes with Adaptive Optics and volcanic plumes have been observed from space with HST. Three further observations by amateur astronomers following our observational alert on 5th August 2021 may indeed show some signatures of the volcanic plume with lower quality, but further scientific assessment will be needed and performed in September 2021.
