Dark lane E from Rho Ophiuchi region. This is the middle of the main part of the great vacant lane that runs east from the region of Rho Ophiuchi. It is about 32' wide and has its beginning in a vacant area in which is the star 22 Scorpii (CD-24°12695, 5.5 arcmin). It runs slightly northeast to about a = 16h 40m, d = -23°40'. From this point it extends in a broken chain of dark spots to a little south of B 63. Its total length is therefore about 10°."
