AWARE: Alert Watcher and Astronomical Rapid Exploration

The previous LIGO/Virgo/Kagra (LVK) O3 run has demonstrated the importance of rapid follow-up observations of binary-neutron star (BNS) and neutron star – black hole mergers (NSBH) electromagnetic counterparts such as short gamma-ray bursts (GRBs) and kilonovae (KNe). However, the localization of LVK events typically spans a few hundred square degrees on the celestial sphere. It is essential to observe the localization contour as much as possible in order to find the fast-decaying optical sources. The issue is that one needs telescope network and automatic scheduler to observe the localization area. In this paper, we discuss two main follow-up tactics: target observations for narrow-field and mosaic scanning for wide-field telescopes. We describe the automatic schedule software AWARE that provides both LVK alert receiving and observation scheduler. The processed alert messages are almost immediately sent to the subscribers via Telegram bot. The asynchronous implementation of AWARE allows scheduler thread in the concurrent mode to create observation plots and plans as a final product. The generated products are adapted for usage in observational systems, for instance, KDS, FORTE or CHAOS. We are attempting to exploit the AWARE with IKI GRB Follow-up Network (GRB-IKI-FuN) in the LVK O4 run.
