Abstract

1. AR9393 and CR1974

Synoptic chart with (upper panel) and without (lower panel) the active region AR9393.

The coronal field lines (Figure 1.2a) calculated using the HCCSSS model (Zhao and Hoeksema, 1995), and magnetic maps at different levels (Figure 1.2b).

Figure 1.3a Figure 1.3b Figure 1.3c Figure 1.3d

The field lines in different heights. The range of the height in Figure1.3a-d are respectively 1.0 - 1.3 Rs, 1.3-1.5 Rs, 1.5-1.8 Rs and 1.8-2.5 Rs.

Figure 1.4

Another presentation of the coronal field lines. The active region AR9393 was near the central meridian.

Figure 1.5a Figure 1.5b

The same as Figure 1.4 but with different height. The range of the height in the Figure 2.5a-b are respectively 1.0-1.8, and 1.8--.
