Using Gaia DR2 photometry we determine an approximate mass of the lens, which we use to calculate the expected microlensing effects. This yields 3914 microlensing events by 2875 different lenses between 2010 and 2065 with expected shifts larger than 0.1 mas between the lensed and unlensed positions of the source. 513 of those are expected to happen between 2014.5 - 2026.5 and might be measured by Gaia. For 127 events we also expect a magnification between 1 mmag and 3 mag.plc2.rawcands A table of candidates for optical microlensing. gaia_source names are the lenses; names with ob_ in front are lensed objects.388519source_idUnique source identifier.
