Observations made with 25cm L at 145x. Comps 131, 128, 126, 123 from aavso
d chart.

SGRV4641 20020521.4298 12.9 LMK
SGRV4641 20020521.4958 12.5 LMK
SGRV4641 20020521.5 12.8 LMK

I watched this object over a half hour period and saw it varied
chaotically from mag 12.5 to 12.8 with a "period" of just a few seconds! I
have never seen such a behavior in a variable star before.
