The detection of gravitational waves (GWs) from the binary neutron star (BNS) coalescence, GW170817, and its electromagnetic (EM) counterparts marked the dawn of multi-messenger astronomy. The observations had fundamental implications in astronomy, astrophysics and cosmology. The current sensitivity of the LIGO-Virgo instruments is almost twice as the previous observing run. While there have been potential candidates, no coincident counterparts have been observed. This means that, in general, detecting counterparts is difficult. The first step towards this needle in a haystack problem is a rapid, robust alert system that reports and disseminates the candidate information including useful data products to external facilities to perform follow-up operations. For the first time, in the third observing run, the LIGO-Virgo alerts are public. In this talk, I will highlight the low-latency campaign of LIGO-Virgo and the dissemination of alerts to facilitate multi-messenger observations.
