IC 3130 involves at least two stars, and probably a defect as well. It appears on Schwassmann's plate as "eF, pS, ?, 140 deg, li plan li". The last phrase decodes to "like an asteroid trail." The nominal position is between the two stars, and there are two other stars in the area which may also be part of the object that Schwassmann thought nebulous.
One of the stars I noted earlier is apparently a defect on the DSS1R plate at 12 18 49.75, +08 14 30.0 (UB10). It does not appear on DSS2 plates, nor in the Gaia, PS1, or SDSS. I've removed the entry (which I had called "I3130 nearby n *") from the position table.
