(survey that recorded microlensing event lightcurves)
Probing Lensing Anomalies Network (PLANET)
was a 1995-2015 collaboration
including a number telescopes world-wide,
to carry out follow-up observations of gravitational microlensing events
(recording their light curves)
in response to alerts of transients by
a number of surveys.
At some point, PLANET partnered with or merged with MicroFUN,
apparently using the name MicroFUN. I have found nothing about
recent PLANET activity.
