Following a prominent activity peak of bright meteors peaking about 0.75 days earlier, the Leonid outburst recurrence of 1998 displayed a second pronounced activity peak in the hours around passage through the node of parent comet 55P/Tempel-Tuttle on November 17.82. Here, we report preliminary video results from two observational networks established in China by the 1998 Sino-Dutch Leonid Expedition. The results suggest that two separate activity structures might have been responsible for the short-lived activity around nodal passage: a B=5 background peaking near 19h20m UT (lambda=235.260, eq. 2000.0) and a B=30 narrow structure peaking near 20h40m UT (lambda=235.316). These come in addition to the broader structure that produced the fireball activity on November 16-17. The two structures near nodal passage appear similar in shape and equivalent width (but not in activity level) to the two structures in the historic 1866 storm display.
