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.
