The Lunar Surface Electromagnetics Explorer 'LuSEE Night' is a low frequency radio astronomy experiment that will be delivered to the farside of Moon by NASA Commercial Payload Services (CLPS) program in late 2025 or early 2026. payload system being developed jointly and US Department Energy (DOE) consists 4 channel, 50 MHz Nyquist baseband receiver 2 orthogonal $\sim$6m tip-to-tip electric dipole antennas. LuSEE Night enjoy standalone operations through lunar night, without electromagnetic...

We expect the monopole signal at lowest frequencies below $100\,$MHz to be composed of two components: deep Rayleigh-Jeans tail cosmic microwave background and distinct features: dark ages trough $\sim 17\,$MHz dawn 75\,$Mhz. These are hidden under orders magnitude brighter foregrounds whose emission is approximately a power-law with spectral index $\approx -2.5$. It usually assumed that signals interest separable from based on smoothness. argue this difficult approach likely impossible for...
