Using McMath-Pierce Facility on Kitt Peak I measured total
B field using Zeeman splitting of Fe 15648 at darkest position in spot umbrae
of 484 and 486 from 19-25 Oct 2003. Because this line is
always completely split, the measures are unambiguous and
accurate within our ability to locate the darkest place.
Resolution is 2 arcsec plus seeing, but believe the field
values are independent of seeing.
