AB: We reconstruct the magnitude of the interplanetary magnetic field B and solar wind speed v at 1 AU using 1) yearly values of sunspot numbers and geomagnetic index aa; 2) available spacecraft measurements of v and B since 1964. We compare our results with the reconstruction done by Stamper et al. (1999) and also with the reconstruction by Svalgaard et al. (2003). References Stamper, R., M. Lockwood and M.N.
