OGLE-2015-BLG-0060 based on observations obtained from 13 different
telescopes. Intensive coverage of the anomalous parts of the light
curve was achieved by automated follow-up observations from the
robotic telescopes of the Las Cumbres Observatory. We show that, for
the first time, all main features of an anomalous microlensing event
are well covered by follow-up data, allowing us to estimate the
physical parameters of the lens. The strong detection of second-order
effects in the event light curve necessitates the inclusion of
longer-baseline survey data in order to constrain the parallax vector.
We find that the event was most likely caused by a stellar binary-lens
with masses M_star1 = 0.87 ± 0.12 Msun and M_star2 = 0.77 ± 0.11Msun.
The distance to the lensing system is 6.41 ± 0.14 kpc and the
projected separation between the two components is 13.85 ± 0.16 AU.
