Possible Nova in the Hyades field? (!)

An ATel (#4513 [1]) just came through suggesting a possible 6th magnitude transient in the Hyades field.

Coordinates are 04:23:29, +17:58:29, 10" error.  A quick check of VSX showed nothing in that position.  Minor Planet Checker also showed nothing.

All followups encouraged, especially from the spectroscopists.  It is possible this is not a real detection, so confirmation of the transient is most critical.

A Special Notice will go out shortly.
