What about an Apparent Magnitude 2.0 when viewed from Earth during the
Passage, as diagramed to the Zeta specs at the Point of Passage page
(http://www.zetatalk.com/theword/tword03y.htm)?  This is much less than
1 AU, being more or less 2/5 of an Earth-Sun distance.  The Zetas said
somewhere, 14 million miles from Earth, no closer.  This would make
Planet X brighter than Magnitude 2.0 (H) and thus an Apparent Magnitude
11 at 9 Sun-Pluto distances, I suspect.  (Asking for a math assist here,
being a math dummy big time).
