GRANDMA Project

GRANDMA is a network of ground facilities dedicated to time domain astronomy. It will be operational during the electromagnetic follow-up of gravitational waves candidates during the next LIGO/Virgo observational campaign (O3).

To contact us, please send a message to antier@lal.in2p3.fr.

It is composed of telescopes (mostly robotics) spread all over the world with photometric and spectrometric capabilities.
