An ATel (#4513 ) 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.
