Comparison of the N V 1238, 1242 Å and C IV 1548, 1550 Å absorption features in the last STIS spectra. In each panel we show day 617, shifted upward for clarity, and day 834 (lower), all fluxes are scaled to 10^-14 erg s^-1 cm^-2 Å^-1. The doublet centroid was chosen as the reference wavelength in each case for displaying the changes. See Fig. 30 for a detailed view of NV in the two epochs.
