Observing Campaign #773: EX Lup outburst coverage requested

View here: Details for EX Lup outburst coverage requested

Abstract: A long-term campaign on the Young Stellar Object EX Lup, which is going into outburst. Photometry and spectroscopy are requested to observe the color evolution around the outburst.

Justification: These outbursts might be due to the same disk instability responsible for dwarf nova eruptions, which has never been properly tested by observing color evolution throughout the outburst.
