P. Kilmartin and A. Gilmore (Canterbury) report on behalf
of the AAVSO International High Energy Network:
We observed the localization of the Swift burst GRB050915
(Grupe et al. GCN 3977) with the 60cm OCS telescope of Mount John
Observatory. 600 seconds of stacked unfiltered observations
with mipoint at 050915.542 (1.6hrs after the burst) reached
a limiting magnitude of CR=18.0 estimated from USNO-A2.0 stars.
No new object is present by comparison with DSS2-R. Observations
are continuing.
