I found from JPL Horizons some data that appears to be postlaunch but pre-insertion -planned orbit on Jan 2, GRAIL A in 88 x 8378 km x 87.2 deg, GRAIL B in 111 x 8359 km x 88.3 deg.
Here's hoping they choose Calvin & Hobbes!

During the prime mission, which stretched from March 1 to May 29, the two GRAIL spacecraft, named Ebb and Flow, orbited at an average altitude of 34 miles (55 kilometers). The average orbital altitude during extended mission will be 14 miles (23 kilometers), which places the GRAIL twins within five miles (eight kilometers) of some of the moon's higher surface features.
"The data collected during GRAIL's primary mission team are currently being analyzed and hold the promise of producing a gravity field map of extraordinary quality and resolution," said Maria Zuber, principal investigator for GRAIL from the Massachusetts Institute of Technology in Cambridge.
I think we'll convert this into a live thread for the EOM. I'll convert it back later.

Burned a little longer than thought, due to remaining fuel in the tanks4 min burn Grail A (EBB)
Here's a heart-felt memory...

A mysterious large mass of material has been discovered beneath the largest crater in our solar system—the Moon's South Pole-Aitken basin—and may contain metal from the asteroid that crashed into the Moon and formed the crater, according to a Baylor University study."Imagine taking a pile of metal five times larger than the Big Island of Hawaii and burying it underground. That's roughly how much unexpected mass we detected," said lead author Peter B. James,
