Abstract: We report on the fastest CME observed during the rising phase of solar cycle 25, when Parker Solar Probe (PSP) flies through a CME on September 05, 2022, during its encounter 13 perihelion. The speed of this CME was measured to be ~2500 km/s putting it in 0.15% of the rare extreme speed CMEs listed in CDAW catalog. PSP cruises at a distance of ~13 Rsun, flies through this CME, its substructures, and eventually an associated current sheet on September 6 during this perihelion period. The in-situ measurements of the current sheet region show classical signatures of magnetic field reversal, high temperatures, and particle speeds that match well with analytical solutions of magnetic reconnection. We relate these measurements with the remote sensing observations from Solar Orbiter, and the results point towards ongoing reconnection while PSP crosses the current sheet. This measurement is the first in-situ observation of ongoing reconnection associated with an eruption in the solar corona.
