We show that a recent purported correction to the effects of Doppler boosting of flux density in an erstwhile published formula for calculating the observer’s motion from the cosmic radio dipole in sky brightness is erroneous. The thereby computed downward correction in the estimated magnitude for the observer’s motion needs to be scrapped and the results derived therefore need to be reverted back to their erstwhile values.
