我们展示了2019年7月2日日全食的合成白光图像，来自太阳活动周期的最小值。我们展示了来自智利三个观测点的高分辨率高动态范围复合图像，其中一个观测点由646个单独的地面图像组成，其视野如此之广，超过了欧洲航天局太阳和日光层天文台上海军研究实验室的C2和C3日冕仪的视野。我们比较了日冕流光和其他日冕磁现象的分辨率。我们还展示了NOAA GOES-16和GOES-17太阳紫外线成像仪观测到的太阳表面特征的连续性。
We present composite white-light images of the 2019 July 2, total solar eclipse, from the minimum of the solar-activity cycle. We exhibit high-resolution high dynamic range composites from three observation sites in Chile, including one made of 646 individual ground-based images and with such a wide field it exceeds the field of view of the Naval Research Laboratory’s C2 and C3 coronagraphs aboard ESA’s Solar and Heliospheric Observatory. We compare the resolution of the coronal streamers and other magnetic phenomena of the corona. We also show continuity of features on the solar surface as observed from NOAA’s GOES-16 and GOES-17 Solar Ultraviolet Imager.
