Jun. 5-6, 2012 - An international campaign to observe the aureole of refracted sunlight in the transiting Venus' atmosphere on June 5-6, 2012 has involved several orbiting spacecraft/instrumentation. There has been a worldwide coordination between NASA's Hubble Space Telescope ACS/WFC3 moon observations, ESA's Venus Express science operations, JAXA's Hinode Solar Observatory/SOT, AURA's NSO/IBIS visible high resolution spectro-imagery, NASA's Solar Dynamical Observatory/HMI and the ground-based Venus Twilight Experiment coronographs. - See e.g. Science News@Analysis, Vol. 336, 11 May 2012 : Venus's Rare Sun Crossing May Aid Search for Exoplanets - T.W.

In order to make it easier for all observers to have access to the observations date & time performed by SOIR on VEX, the SOIR team has built a web tool which allows the user to find past and near-future observations of SOIR corresponding to several search criteria. This tool can be accessed freely with no password needed through our web site at the following address : [1] SOIR solar occultation opportunities in the period 1/1/2012-31/12/2012 are described in the following file: File:SOIR MTP76-MTP86.xls For further details, contact the SOIR Principal Investigator: Ann-Carine Vandaele <A-C.Vandaele@aeronomie.be>

This file describes all VeRa radio occultations carried out in the period 1/7/2006 - 2/6/2010. For further information contact the VeRa team: Martin Paetzold <Martin.Paetzold@uni-koeln.de>, Bernd Hauesler <Bernd.Haeusler@unibw.de>, and Silvia Tellmann <tellmann@geo.uni-koeln.de> This file describes all opportunities for Radio occultations in occultation seasons in January 2011 - November 2012. File kindly provided by Stefan Remus, ESAC. Note that not all radio occultation opportunities are exploited.

Other linksThe Venus Exploration Analysis Group, established in 2005, is NASA's community-based forum designed to provide scientific input and technology development plans for planning and prioritizing the exploration of Venus over the next several decades (Between 23 May and 9 June 2007 - ESA web site) The Venus ground-based image Active Archive (VAA) allows you to upload and retrieve ground-based Venus observations obtained in infrared, visual or ultraviolet light. The aim of this archive is to complement the Venus Express (VEX) spacecraft observations of Venus with worldwide ground-based images to allow for continuous monitoring of the planet. |
