我们简要地描述了我们在2007年协调的两个多仪器观测活动，并取得了一些初步结果。第一个（Hinode HOP 7）是SOHO/Hinode/TRACE/STEREO/Ulysses为期一周的活动，于2007年5月在SOHO-Ulysses quadrature期间进行。我们无法实现所有的目标，但我们非常幸运，因为“Del Zanna”活跃区域出现在太阳的正确经度上，并且观察到灯丝喷发和CME。特别重要的是，在Hinode/EIS观测到的长丝喷发区域的所有日冕线中发现了大的（100公里/秒）非热增宽。第二次活动（Hinode HOP 44）涉及SOHO （CDS、SUMER、UVCS）、Hinode、TRACE，于10月30日至11月4日测量了从低日冕到1.7太阳半径的极日冕洞的羽流/羽间区物理参数。我们获得了一组很好的观测结果，然而各种仪器的限制和缺乏充分发展的羽流限制了我们的目标。
We briefly describe two multi-instrument campaigns we coordinated to observe the off-limb corona in 2007, with some preliminary results. The first (Hinode HOP 7) was a SOHO/Hinode/TRACE/STEREO/Ulysses weeklong campaign during the SOHO-Ulysses quadrature in May 2007. We could not achieve all of our goals, however we were very fortunate in that the ’Del Zanna’ active region appeared on the Sun at the right longitude, and that a filament eruption and a CME was observed. Of particular significance is the finding of large (100 km/s) non-thermal broadenings in all coronal lines in the region where the filament was erupting observed by Hinode/EIS. The second campaign (Hinode HOP 44) involved SOHO (CDS, SUMER, UVCS), Hinode, TRACE to measure the physical parameters of plume/interplume regions in the polar coronal holes from the low corona to 1.7 solar radii, on 30/10 – 4/11. We obtained a good set of observations, however various instrumental constraints and the lack of fully developed plumes limited our goals.
