From whi at mailman.ucar.edu Sat Apr 22 13:49:27 2023 From: whi at mailman.ucar.edu (Whole Heliosphere and Planetary Interactions) Date: Sat, 22 Apr 2023 13:49:27 -0600 Subject: [WHPI] STEREO SECCHI High Telemetry Campaign Message-ID: We would like to make the Heliophysics and connected communities aware of an upcoming high-telemetry period for STEREO -A/SECCHI, between July 3 - Aug 4, 2023 in conjunction with STEREO-A?s approach to the Earth-Sun line later in August. The campaign will include higher cadence, low compression EUV images and higher cadence coronagraph images. If any observatory would like to support this effort through campaign science targeting, please email gsfc-stereo at mail.nasa.gov, and we will add you to a target planning email list. We are also interested in already existing plans for compatible observations during this time period. Target suggestions can be submitted (again to gsfc-stereo at mail.nasa.gov) and the STEREO/SECCHI team will choose some for focus during this period, to be advertised through the WHPI Campaign page in order to enable observatories to coordinate. General science targets and goals are: - Active regions: The structure of complex active regions, so we are interested in data that provides information on AR magnetic fields, temperatures, and densities. - Low latitude coronal hole boundaries: Determining their characteristics at the Sun and how those propagate outwards into the corona and perhaps the solar wind. - Coronal outflows/intermittency to characterize the spatial/temporal scales of small-scale structure at the origins of the solar wind. For this, we need off-limb information (imaging, spectroscopy) below about 2-3 Rsun to connect w/ the COR2 deep-field images. -- --------------------------------- *Sarah Gibson * Senior Scientist, HAO/NCAR (she/her) Phone: 303 497 1587 Fax: 303 497 1589 3080 Center Green Drive Boulder, CO 80301 -------------- next part -------------- An HTML attachment was scrubbed...
