| Comments |
The Doppler shifts of 2 blobs at 1.67 and 1.90 Ro of the PA=45 observations show changing shift from one to the next exposure, indicating possible helical motion. However, since this only occurs in two exposures in the available data, existence of helix or not can not be definitely certain.
