The merging of binary neutron stars (BNSs) produces gravitational waves capable of being
detected by Advanced LIGO and Virgo before the time of merger. Therefore, the merger event
can be detected before the electromagnetic counterpart. The early warning gravitational wave
detection pipeline was previously tested in Sachdev et al. [1]. Here we will build off that testing
with an updated method of data recoloring to more closely simulate real signals. We will be
narrowing the range of frequencies investigated in the original paper to look solely at 49 Hz. By
enabling the early warning of gravitational wave event, an organized observing group including
several telescopes has the potential to observe the merger seconds before the event occurs.
