9800476 Simonetti A High-Resolution, High-Sensitivity H-alpha and SII Survey of the Northern Galaxy. The objective of this project is the production of two major imaging surveys of interstellar line emission from that part of the Galaxy visible from the northern hemisphere. The first survey will consist of images of the faint hydrogen Balmer-alpha emission from the warm ionized interstellar medium over the northern celestial hemisphere. The second survey will comprise images of the interstellar forbidden line emission of ionized sulfur, and will cover the northern Galaxy between latitudes of plus/minus 20 degrees. The results of the surveys will be digital atlases available to the astronomical community.

小行星9800476 北方星系的高分辨率、高灵敏度H-α和SII巡天。 该项目的目标是对从北方半球可见的那部分银河系的星际线发射进行两次主要的成像调查。 第一次巡天将包括从北方天半球上方温暖的电离星际介质发出的微弱的氢巴尔默-α辐射的图像。 第二次巡天将包括电离硫的星际禁线发射图像，并将覆盖北方银河系正负20度之间的纬度。 调查结果将成为天文学界可利用的数字地图集。
