Rob's observations compare favourably with my two reports of this object
(88- 50 A).
The latest of Feb 23rd had a mag 3.5->inv flash pattern A'fA' with
secondary flash mag4. Time period was 11.643 which compares very well
with
his 5 or 6 seconds if my secondary flash was a little brighter and
counted.
My obs of November 13th 1996 indicated a more complex flash pattern of
F'fffF' mag 2.5->inv with secondary flashes mag 4.5 .The flash periods
averaged 10.077secs. It would appear to have a couple of small
appendages
to make up the extra two secondary flashes seen on this occasion.
