Here's the view of Enceladus during the plume search tomorrow:



Both Saturn and the sun are on practically the opposite side of Enceladus from Cassini during the observation (sun phase angle 162 degrees; Saturn phase angle 164 degees).

The sub-Cassini point on Enceladus will be 0.8 degrees N, 171 degrees W--so the limb is approximately the 81W/99E meridians.

Here's a comparison to theplume search they did on Feb. 17, 2005:



That was somewhat further away than today's observation (282,000 km vs. 183,000 km) and the solar phase angle was a bit less (154 degrees), also a bit more saturnshine (129 degrees). So today's observation is more favorable all around.

Here was the result of one long-exposure NAC image Feb. 17th:
