我们调查的日冕成像能力的太阳紫外线成像仪（SUVI）上的地球同步业务环境卫星-R系列航天器。SUVI名义上指向太阳，提供六个极紫外（EUV）波长的太阳图像。在轨数据表明，SUVI具有足够的动态范围和灵敏度，可以对太阳上方最高高度的日冕成像，同时对太阳成像。我们开展了一项活动，调查EUV信号的存在远远超出了太阳EUV成像仪的标称太阳中心成像区域。我们偏离了SUVI的视线，几乎是太阳周围的一个成像区域。我们提出了我们在太阳活动周期接近最小值时进行的活动的细节，以及确认EUV辐射存在于三个太阳半径之外的一些结果。
We investigate the coronal imaging capabilities of the Solar UltraViolet Imager (SUVI) on board 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 the SUVI line of sight by almost one imaging area around the Sun. We present the details of the campaign we conducted when the solar cycle was at near the minimum and some results that confirm that EUV emission is present to beyond three solar radii.
