Magnetars are slowly-rotating neutron stars with extremely strong magneticfields that rarely produce extremely bright, energetic giant flares. MagnetarGiant Flares (MGFs) begin with a short (200 ms) intense flash, followed byfainter emission lasting several minutes that is modulated by the magnetar spinperiod (typically 2-12 s). Over the last 40 years, only three MGFs have beenobserved within our Galaxy and the Magellanic Clouds, which all suffered frominstrumental saturation due to their extreme intensity. It has been proposed,that extragalactic MGFs masquerade as a small subset of short Gamma-ray Bursts(GRBs), noting that the sensitivity of current instrumentation prevents us fromdetecting the pulsating tail to distances slightly beyond the MagellanicClouds. However, their initial bright flash is readily observable out todistances of < 25 Mpc. In this presentation, we will evaluate the spectral andtemporal behaviors of MGFs using recent observations from events such asGRB200415A, to differentiate them from other progenitors, such as short GRBs.We then present an overview of the Moon Burst Energetics All-sky Monitor(MoonBEAM), which will attempt to discover more of these events, providinghighly sensitive data that will help unravel the nature of these phenomenafurther in an attempt to better understand their emission mechanismscomparatively with GRBs. In doing so, MoonBEAM will help provide acomprehensive picture of energetic astrophysical phenomena, a key goal of theAstro2020 decadal survey.
