Grindlay, M. Garcia, and P. Zhao, CfA, report: "B. McLean obtained moderately deep I-band imaging of the EXOSAT error circle for EXO 1846-031 (Parmar et al., ibid.) with the 1.2-m telescope at the Whipple Observatory on Oct. 14.15 UT. No optical counterpart brighter than I = 21.5 in the EXOSAT error circle was detected, suggesting that the source is either very distant or heavily absorbed or that this outburst decayed more quickly. Deeper observations would still be useful." 1994 October 15 (6096) Daniel W. E. Green
