We describe the INTEGRAL Burst Alert System (IBAS): automatic software for rapid distribution of coordinates Gamma-Ray Bursts detected by INTEGRAL. IBAS is implemented as a ground based system, working on near-real time telemetry stream. During first six months operations, GRB have been in field view instruments and localized IBAS. Positions with an accuracy few arcminutes are currently distributed to community follow-up observations within tens seconds event.
Aims.With the ongoing AKARI infrared sky survey, of much greater sensitivity than IRAS, a wealth post-AGB objects may be discovered. It is thus time to organize our present knowledge known stars in galaxy with view using it search for new among sources.
