Abstract
Very low signal to noise with Halca-GRTs baselines though fringes were detected. No short spacing available less than 100 M lambda. Imaging was made with self-cal for both phase and amplitude. There were two fetures with separation about 8 mas in NE-SW direction, which are consistent with USNO images.

Comments on Difmap processing
Only phase self-cal was performed with selfflag false, 3,4 mode. There were two fetures with separation about 4 mas in N-S direction, which are consistent with USNO images.
