We investigate the coronal imaging capabilities of the Solar UltraViolet
Imager (SUVI) on the Geostationary Operational Environmental Satellite-R series
spacecraft. Nominally Sun-pointed, SUVI provides solar images in six Extreme
UltraViolet (EUV) wavelengths. On-orbit data indicated that SUVI had sufficient
dynamic range and sensitivity to image the corona to the largest heights above
the Sun to date while simultaneously imaging the Sun. We undertook a campaign
to investigate the existence of the EUV signal well beyond the nominal
Sun-centered imaging area of the solar EUV imagers. We off-pointed SUVI
line-of-sight by almost one imaging area around the Sun. We present the details
of the campaign conducted when the solar cycle is at near the minimum and some
results that affirm the EUV presence to beyond three solar radii.
