🔭GRANDMA Telescopes
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@ijclab.in23.fr.
It is composed of telescopes (mostly robotic) spread all over the world with photometric and spectrometric capabilities.
