This paper is based on a proposal submitted for a BRICS astronomy flagship program, which was presented at the 2019 meeting of the BRICS Astronomy Working Group, held in Rio de Janeiro from 29 September to 2 October 2019. The future prospects for the detection and study of transient phenomena in the Universe heralds a new era in time domain astronomy. The case is presented for a dedicated BRICS-wide flagship program to develop a network of ground-based optical telescopes for an all-sky survey to detect short lived optical transients and to allow follow-up of multi-wavelength and multi-messenger transient objects. This will leverage existing and planned new facilities within the BRICS countries and will also draw on the opportunities presented by other multi-wavelength space- and ground-based facilities that exist within the BRICS group. The proposed optical network would initially perform followup observations on new transients using existing telescopes. This would later expand to include a new global network of \sim ∼ 70 wide-field 1-m telescopes which will cover the entire sky, simultaneously, with a cadence of less than a few hours. This realization would represent a ground-breaking and unique global capability, presenting many scientific opportunities and associated spin-off benefits to all BRICS countries.
本文基于提交给金砖国家天文学旗舰计划的一份提案，该提案在2019年9月29日至10月2日于里约热内卢举行的金砖国家天文学工作组2019年会议上进行了展示。宇宙中瞬变现象探测与研究的未来前景预示着时域天文学的一个新时代。本文介绍了一个专门的全金砖国家旗舰计划，旨在开发一个地面光学望远镜网络，用于全天巡天，以探测短寿命光学瞬变现象，并对多波长和多信使瞬变天体进行后续观测。这将利用金砖国家现有的和计划中的新设施，同时也将借助金砖国家集团内其他多波长空间和地面设施所带来的机遇。提议的光学网络最初将使用现有望远镜对新的瞬变现象进行后续观测。之后，它将扩展为一个由约70台1米口径宽视场望远镜组成的新全球网络，这些望远镜将以小于几小时的时间间隔同时覆盖整个天空。这一设想将代表一种开创性的独特全球能力，为所有金砖国家带来众多科学机遇和相关的附带利益。
