I think you mean:
USNO Star Mag: 15.1 (Blue) 13.8 (Red)
Field: 476
Magnitude: 14.29
RA: 04h 22m 49.85s Dec: +12°07'44.16"
RA: 04h 22m 40.05s Dec: +12°07'19.92" (Epoch 2000)
but this is the bright (relatively) star just above and to the right
of the frame 3 defect chosen by Lieder as the "white" persona. Havas
is excited by his "red" persona which seems to be a star and which is
not apparent in my 11 disk copy of the USNO-a2.0
