Aurora activity resulting from the CME August 1st.
Took about three days to arrive from 149597870.691 kilometers (1 A.U) away.
Do the math and post a reply with the speed in Kilometers per hour and Miles per hour.
Here’s some quick math from Susan in Tennessee:
2,077,748.2 km/hr or 1,291,053 mi/hr
Making the assumption that it takes a full three daysâ€¦
3 days * 24 hr/day = 72 hr
149,597,870.691 km / 72 hr = 2,077,748.204 km/hr
There are 0.62137 miles in a kilometer, so
2,077,748.204 km/hr * 0.62137 mi/km = 1,291,050.401 mi/hr
Youâ€™ll have to excuse my not worrying about significant digits and such
If we take Susan’s 2,077,748 km/hr and divide by 60, then take the result and divide by 60, we get 577 km/sec
Solar wind is between 400 and 700 km/sec. Keep in mind people, these are really rough numbers, but they are pretty close.
