The data set was taken on 1999 June 1 starting at 09:13 UT. Below each image we show the resulting line profile for both O V and N V taken at the same time at five different temporal locations (09:47, 09:53, 10:00, 10:03 and 10:05 UT) labeled a)- e), normalized to unity. The quiet Sun profile is over-plotted for comparison (dashed line).

The gaps in the TRACE light curve are missing data due to the presence of cosmic rays.
