Note: Arrival time following a data gap in solar wind data from 2023-12-17T05:53Z-2023-12-17T07:32Z. Following the data gap, there is an enhancement in magnetic field components from 8.14 nT to 13.7 nT, peaking at 15.69 nT. The Bz reaches -13.9 nT at DSCOVR and undergoes several rotations. There is an increase in solar wind speed from 435 km/s to 525 km/s, increases in density from 18 cm^-3 to over 25 cm^-3, and an increase in temperature at the time of the shock. The temperature begins to decrease around 2023-12-18T13:40Z. The solar wind speed starts to decrease around 2023-12-18T15:30Z to approx. 470 km/s. The arrival of this CME was also detected at STEREO A around 2023-12-17T00:30Z, following a data gap.
