  The temperature anisotropy power spectrum measured with the Wilkinson
Microwave Anisotropy Probe (WMAP) at high multipoles is in spectacular
agreement with an inflationary Lambda-dominated cold dark matter cosmology.
However, the low order multipoles (especially the quadrupole) have lower
amplitudes than expected from this cosmology, indicating a need for new
physics. Here we speculate that the low quadrupole amplitude is associated with
spatial curvature. We show that positively curved models are consistent with
the WMAP data and that the quadrupole amplitude can be reproduced if the
primordial spectrum truncates on scales comparable to the curvature scale.
