Notes. Columns (1)–(4) present the respective observer and its location in Carrington coordinates (with the first row providing the flare location). Column (5) lists the measured solar wind speed. Columns (6)–(7) and (9)–(10) provide the backmapped magnetic footpoints of the observer at the solar surface using the simple PFSS and the ADAPT-WSA models, respectively. Column (8) presents the magnetic field polarity observed (O) in situ and modeled (M) by ADAPT-WSA and PFSS.

(a)

PFSS and ADAPT-WSA footpoints at 1 R.

(b)

Longitude and latitude values are given in the Carrington coordinate system.

(c)

Average and standard deviation values calculated from all 12 realizations of the ADAPT-WSA.

(d)

This is not an observational value but a nominal value consistent with ENLIL simulations.
