RAPAS Network

Réseau Amateurs Professionnels pour les Alertes Scientifiques — a Pro-Am network for rapid optical counterpart identification of transient alerts (GRBs, SNe, NEOs). Using standardized Gaia-compatible filters (G/BP/RP) for network-wide photometric consistency. This filters are lent by the RPAPAS group.

Coordinated by W. Thuillot (IMCCE), Th. Midavaine (SAF), M. Dennefeld (IAP), Ch. Buil (ARAS). Supported by Observatoire de Paris-PSL.
