February 1, 2019. Wind speeds surrounding Earth's magnetic field broke 1000 km/s again at 1206 km/s for approximately 16 minutes on 2/1/2019 at 00:39:05 UTC after more extreme turbulence in Earth's magnetotail that began 3 1/2 hours earlier.

Yesterday they reached into the 900's and 700's the day prior with some relative calm the day before.

But, we can add today to the string of 25 days of breaking 1000 km/s since January 5th

Solar winds only reached 550 km/s. Earth's magnetospause continues to buckle from the extreme pressure.
