From a shot during the observation effected by Paolo Lazzarotti on Oct. 3rd 2004 (h.01:14UT),  a rille is visible – north from the known G. Bond rille. It extends orthogonally to G. Bond rille, overlapping  for a short tract - thus creating a T-shape formation.
From a search on the existing atlas such as Lunar Orbiter (image IV-079-H1) and Consolidated (b3 picture), this rille is not visible in the light conditions during the satellite shooting.
The only evidence of the rille existence is in the PDS MAP-A-PLANET; the picture is identified as 1097399465 and it can be downloaded from the website:
http://pdsmaps.wr.usgs.gov/PDS/public/explorer/html/moonadvc.htm inserting the G.Bond crater (Long. 36.2   lat. 32.4).
In this picture a long rille is well visible – stretching along the Lacus Somniorum eastern edge (pictures 4 – 5).

As it is visible in Clementine image detail, a long rille  stretches along the Lacus Somniorum eastern edge. It extends from West to East and ends just close to the southern area of Maury B. crater. Its size should be roughly 240 / 250 km. For about 45-50 km. it stretches westwards the G. Bond rille and for the remaining 190-200 km. eastwards the G. Bond rille.
Its trajectory is probably interrupted by a small crater visible in  picture 4 (in this case it appears very bright). The maximum width should be 3-3.5 km.

Even  Rukl atlas does not show the rille (detail picture 6). Lunar chart no. 27 (LAC) instead shows it only partially (picture 7).
