. Fig. The SOHO/EIT 171 image (a) illustrating a pronounced transequatorial inverted V-shaped chain 1-2-3-4 which appears to outline the large soft X-ray CH observed with the Yohkoh/SXT (b) on March 1-2, 1999. The BBSO H-alpha (c) and MLSO/HAO He I 10830 (d) heliograms are shown to demonstrate relation of this and some other EUV chains to other large-scale structures such as H-alpha filaments and He I 10830 features.
