I've been looking through Corona
some more, and I think I've found a Spaceflight Chronology
nod after all. Toward the end, it cites Epsilon Eridani as Vulcan's home star, rather than the generally accepted and now near-canonical 40 Eridani. Epsilon Eri was also chosen as Vulcan's primary by the SFC and referenced in Strangers from the Sky
, at least according to Memory Beta.
The book does have some odd continuity glitches, though, like referring to Andorians as "Andorrans." Maybe there was a copyeditor who thought they were from a tiny European principality.
