And the crowning achievement of Kumeu Observatory so far was the detection of OGLE-2019-BLG-0960 Lb the smallest mass-ratio microlensing planet found to date.The microlensing alert on OGLE-2019-BLG-0960 had been called off but our then student observer and local Kumeu lad Andrew Marmont decided to to take an hours worth of extra “normalizing” data on the target before moving on to a new alert, it was lucky he did so because that hour of extra data became crucial for the detection of the exo-planet.This led to the then Kumeu team of Andrew Marmont, Jonathan Green & Steve Hennerley having our names put down as lead authors on the resulting paper which was then published in the Astronomical Journal …….https://iopscience.iop.org/…/10.3847/1538-3881/ac1582/meta
