Multiple solar flares and solar filament eruptions were observed from 21-23 Jan, 2024. The associated coronal mass ejections (CMEs) were analyzed and modeled. Results of these analysis show potential impacts at Earth as early as late in the day on 24 Jan, with more likely impacts on 25-26 Jan, 2024. As a result, forecasters currently anticipate G1-Minor geomagnetic storm levels over these three days, with higher storm levels possible if more of a direct impact and/or stronger connection with Earth's magnetic field lines occurs. Analysis continues on the multitude of CMEs currently aimed at Earth.
