Background image of the entire SDO/AIA 171 Å solar disk at the time of the FOXSI-3 observations (September 7, 2018, at 17:24 UT). Solar activity was very low at the time of the FOXSI-3 rocket launch. A very aged nonflaring active region was located in the western hemisphere. The colored squares represent the approximate FOV of a silicon detector and the targets during the FOXSI-3 observations. These boxes are approximate FOVs because every detector is clocked differently.
