First Results from Coordinated Observing with IRIS, Hinode, and Ground-Based Observatories (Invited)
Abstract
The NASA Small Explorer Interface Region Imaging Spectrometer (IRIS) was launched in June, 2013, and underwent successful commissioning in July and August. IRIS obtains UV spectra and images with high spatial resolution (0.33 arcsec) and high time cadence (1 sec) of the chromosphere and transition region of the Sun. It does not measure magnetic fields, and so the mission plans from the beginning have included coordination with other observatories to provide these, as well as additional coverage of chromospheric and coronal images and spectra. Coordinated observing with Hinode and with ground-based observatories, including Big Bear, the National Solar Observatory, and the Swedish Solar Telescope on La Palma, began in August. An extended campaign with SST from late August through early October (HOP 236) has been scheduled, performed by LMSAL and Oslo Co-I's. In these campaigns, Hinode SOT provides photospheric magnetic fields with high resolution and sensitivity, and the ground-based observatories provide chromospheric magnetic field measurements (and other images) in Ca II 8542 and/or He I 10830. IRIS performs observations from its initial observing plan on a variety of solar targets, and the other observatories follow its lead. This talk will describe some of these coordinated campaigns and first scientific results from them.
