Estimated CME and type II burst heights (lower emission lane, the two separate lanes overlap after 01:00 UT) for the 15–16 January 2005 event (Event No. 18). The the lanes overlap after 01:00 UT. The Wind WAVES frequency range is as in Fig. 2. The LASCO C3 image difference image shows the CME at 00:18 UT, at height 24.9 R_⊙, at central position angle of 325°  (counterclockwise from the top). This was a full halo CME. Estimated first SEP injection time was at 22:52   ± 5 UT.
