All is set for our attempt tonight. Amazingly, it looks like the weather forecast is good for southern California (Palomar), southern Arizona (Vatican Observatory), southern New Mexico (Apache Point, Magdalena Ridge Observatory), and also Mauna Kea and Haleakala (UH 88inch and Faulkes 2m, respectively). I believe this to be some sort of record.
Bill Ryan at MRO got a nice comparison light curve from last night, which will be quite useful for definitely identifying tonight's event.
Between all of the observatories we will have two full rotations, so even thought it might be painful, I believe we will be able to stitch together a full dataset for comparison.
