"Photometry of the object pointed out by us in GCN 924:
start time Jan 27.0451; R = 21.3 +- 0.2 ; exp. time 30 min
start time Jan 27.0687; R = 21.3 +- 0.4 ; exp. time 20 min
Calibration star: USNO U350_08031605.
The hypotized short term variability (GCN 924) is excluded.
Although these values are well above the detection limit of DSSII-red,
the object is not present on it. This behaviour is consistent with a
long term, large amplitude variable or an eclipsing binary.
