Paul and all,
After doing some research I'm inclined to call Sirko Molau's shower #69 the Andromedids as well.
It agrees fairly well with all current projections for the radiant (Kronk, Jenniskens).
Molau puts the radiant for shower at RA 24.6, Dec +26.5 on Nov 9, with activity from the 8-15th.
Nov 15 Radiant would be 25.8, +33.
Kronk gives the AND radiant as RA 026 Dec +37. Activity Period Sept 28-Dec 5. Peak Nov 14.
Jenniskens (IAU Shower #18) Peak Nov 14 at RA ~ 24 Dec ~ 32.5, activity 10/8-11/22.
So while Kronk and Jenniskens give a very long activity period, Molau supports detectable activity from the 8-15 of November from a radiant agreeing with Jenniskens, and only 4 degrees off from Gary.
Thanx very much for bringing up the subject, Paul!!
That's my 2 cents
Wayne
