abstract of observational proposal

Main Objective: Multi-wavelength, multi-viewing angle observations of a flare

Scientific Justification: Solar Orbiter's upcoming flare campaign will provide observations of high energy flare processes in the corona (X-ray spectroscopic imaging & EUV imaging), chromosphere ((E)UV spectroscopy) and photosphere (optical light imaging and polarimetry). Coordination with Hinode and IRIS provides an unprecedented opportunity to study these processes in similar energy bands from substantially different viewing angles and at all layers of the solar atmosphere.

request to XRT

Normal mode: thin-be and med-be at a 1 min cadence, with med-be and thick-be in the pre-flare buffer (cadence as fast as possible)

Flare mode: thick-be, 2 s cadence, with med-be in context every 10 images

request to EIS

EIS will respond to the XRT flare trigger.
Set up hunter study Flare266_Hunter01 and enable the XRT flare trigger with response study Flare_SNS_v2.

other participating instruments

IRIS requests:
Contacted IRIS team directly as this is a Solar Orbiter coordination
