Eric, Jeff and I divided up the task of inspecting the top multiplets. I'm doing those with rank mod 3 = 0. Here are my comments thus far:

Many of the top scoring 200 pixels are from one of two regions: ~21.5 RA, ~10.1 Dec; or 5.4-5.5 RA, 28.5-29.5 Dec.
Any specific reasons for this? Are these directions more likely to be affected by RFI from local RADAR, or known communications satellites?
Alternatively, are there any nearby stars within these pixels with planetary systems?

The most recent top scoring pixels now focus on a region around 23.66 RA 13.5 Dec.
This doesn't correspond with any known geostationary satellite.
According to the SDSS sky survey, there is a magnitude 15 star at that position. I'm not reading much into that, since you can find a faint star almost anywhere you care to look. However, for those that want to follow this up the coordinates are:
SDSS J013439.49+133008.0
Object ID 1237649918969446408
RA 23.6645527070509 DEC 13.5022256386534
I can't find any other information about it (distance, spectra, etc.)
