McCracken (2007) inverted the galactic cosmic ray record for the interval 1428-2005 to estimate annual averages of the heliomagnetic field (HMF) near Earth during this interval. Quoting from his abstract, "There is good agreement with the results obtained by others using two independent methodologies based upon the sunspot [Solanki et al., 2002] and geomagnetic [Lockwood et al., 1999] records There is disagreement with another method based on the geomagnetic record [Svalgaard and Cliver, 2005] that needs to be resolved." We address the reported disagreement of our long-term reconstruction of the HMF strength with that obtained in the other three studies. We show that a recent reconstruction of the HMF by Rouillard, Lockwood, and Finch [2007] agrees much more closely with that of Svalgaard and Cliver than that of Lockwood et al. to the point where a consensus seems to be reached. We suggest that the discrepancy between McCracken's cosmic-ray-based HMF reconstruction and those based on geomagnetic data originates in the Forbush and Neher ionization chamber data (1933-1957) used to bridge the time gap between the 10Be time series (1428-1930) and the Climax neutron monitor record (1951-present).
