  We present sub-arcsecond imaging in [Ne V] of N49, the brightest optical SNR
in the LMC. Between the "cool" optical and "hot" X-ray regimes, [Ne V] emission
indicates intermediate temperatures for collisionally excited plasmas (2--6 x
10E5 K), for which imaging has been extremely limited. We compare the flux in
these images to the O VI measured spectroscopically by FUSE in individual
apertures and find dereddened line ratios that are reasonably consistent with
our predictions for intermediate velocity shocks. The overall luminosity in [Ne
V] for the entire remnant is 1.2E36 erg/s, which, given the measured line
ratios, implies an overall O VI luminosity of 1.5E38 erg/s. These large
radiative losses indicate that this material must have been shocked recently
relative to the total lifetime of the remnant. We also explore the complex
spatial structure. We find [Ne V] tracing the [O III] emission more closely
than it does H-alpha, measure significant shifts (~0.1 pc) between the peaks of
different emission lines, and find two orders of magnitude variations in the
flux ratios for different filaments across the remnant. These properties as
well as the general filamentary character of the optical emission suggest
thermally unstable intermediate velocity shocks.
