To explain, this was a Partial Penumbral Eclipse. A Total Penumbral Eclipse would only dim the entire surface of the Moon because only the fuzzy outer edge of the Earth's shadow (the penumbra) is blocking the Sun. You don't get that eerie dark red appearance that a total lunar eclipse gives.
So this Partial Penumbral Eclipse was so slight that only folks that stare at the Moon on a regular basis could even notice and only cameras and telescopes would really be able to see a noticeable difference from the normal full Moon.
Here's a photo I took during the peak eclipse coverage. This is a stacked image of 105 frames, processed in RegiStax6. Notice the light shadow on the lower right limb? Yup, that would be the full extent of the action.
Definitely mark your calendars for the next FULL lunar eclipse on April 15, 2014.
