We present the first images of a coordinated campaign to follow active regionNOAA 12709 on 2018 May 13 as part of a joint effort between three observatories(China-Europe). The active region was close to disk center and enclosed a smallpore, a tight polarity inversion line and a filament in the chromosphere. Theactive region was observed with the 1.5-meter GREGOR solar telescope onTenerife (Spain) with spectropolarimetry using GRIS in the He I 10830 \r{A}spectral range and with HiFI using two broad-band filter channels. In addition,the Lomnicky Stit Observatory (LSO, Slovakia) recorded the same active regionwith the new Solar Chromospheric Detector (SCD) in spectroscopic mode atH$\alpha$ 6562 \r{A}. The third ground-based telescope was located at theFuxian Solar Observatory (China), where the active region was observed with the1-meter New Vacuum Solar Telescope (NVST), using the Multi-Channel HighResolution Imaging System at H$\alpha$ 6562 \r{A}. Overlapping images of theactive region from all three telescopes will be shown as well as preliminaryDoppler line-of-sight (LOS) velocities. The potential of such observations arediscussed.
