The large-scale temperature structure of the low corona is investigated using synoptic temperature maps, derived from the intensity ratio of the green (Fe XIV) and red (Fe X) coronal lines as observed at the National Solar Observatory/Sacramento Peak. This intensity ratio is sensitive to coronal plasma with temperatures of 1-2 MK, a range of temperatures usually associated with the quiet corona. The synoptic maps indicate an association between high coronal temperature and the large-scale magnetic field. A comparison with Stanford `source surface' synoptic maps shows that, especially when the heliospheric current sheet is stable over several rotations, the large-scale high-temperature features follow the current sheet remarkably well. For recent Carrington rotations, temperature maps are available for four heights between 1.15 and 1.45 Rsolar. For these maps the correspondence with the current sheet (calculated at 2.5 Rsolar) improves with height. Discrepancies between temperature structure and magnetic structure appear to be largest when the magnetic structure changes rapidly from rotation to rotation.
