    1. OPTICON Call for Proposals 2026<\/h3>\n\n\n\n

    The OPTICON Alliance -an alliance of small- to medium-aperture telescopes with historical roots in OPTICON (the Optical Infrared Coordination Network for Astronomy, formerly supported by the OPTICON RadioNet Pilot programme of the European Commission)- is pleased to announce its Call for Proposals.<\/p>\n\n\n\n

    The OPTICON Alliance continues the legacy by providing open-access Trans-National Access to the facilities of its member institutions.<\/p>\n\n\n\n

    Instructions for telescope time applications are available at: https:\/\/opticon-alliance.eu<\/a><\/p>\n\n\n\n

    Deadline for submissions: April 17, 2026, at 23:59 UT<\/strong><\/p>\n\n\n\n

    2. Call for NRT proposals – 2026B<\/h3>\n\n\n\n

    This is the 2026B semester call for proposals to observe with the Nancay Radio Telescope. The submission deadline is:\u00a01 May 2026<\/strong>.<\/p>\n\n\n\n

    The Nancay Radio Telescope (NRT, France) is a high sensitivity (1.4 K\/Jy at 21cm) meridian telescope (the tracking duration is 1 hour, and varies approximately as 1\/cos(DEC) ) with full polarization capability in the frequency range from 1.1 GHz to 3.5 GHz. The declination limit is > -39 deg. It is operated by the Observatoire de Paris, the Centre National de la Recherche Scientifique and also funded by the Region Centre-Val de Loire. <\/p>\n\n\n\n

    The NRT proposal call is open to the international community. <\/p>\n\n\n\n

    Forms and explanations: https:\/\/www.obs-nancay.fr\/nrt-support-pages\/<\/a><\/p>\n\n\n\n

    Proposals are to be sent to: lucas.guillemot at cnrs-orleans.fr<\/a> .<\/p>\n\n\n\n

    La multiplicit\u00e9 des missions vers les lunes Galil\u00e9ennes soul\u00e8ve des questions majeures sur les conditions de formation et d\u2019\u00e9volution et diff\u00e9rentiation des satellites. Nous proposons un atelier visant \u00e0 rassembler la communaut\u00e9 fran\u00e7aise, fortement engag\u00e9e dans les missions JUNO, JUICE et Europa-Clipper ainsi que la future mission Tianwen-4. L’objectif de cet atelier est d’amener les personnes travaillant sur diff\u00e9rents mod\u00e8les (formation, dynamique, structure interne) afin de cr\u00e9er une communaut\u00e9 consciente des contraintes physico-chimiques issues des autres disciplines.<\/p>\n\n\n\n
