It is well known that, for asymptotically flat spacetimes, one cannot in ge
neral have a smooth differentiable structure at spacelike infinity, i(0). N
ormally, one uses direction dependent structures, whose regularity has to m
atch the regularity of the (rescaled) metric. The standard C->1-structure a
t i(0) ensures sufficient regularity in spacelike directions, but examples
show very low regularity on I+ and I-. The alternative C1+-structure shows
that both null and spacelike directions may be treated on an equal footing,
at the expense of some manageable logarithmic singularities at i(0). In th
is paper, we show that the Kerr spacetime may be rescaled and given a struc
ture which is C->1 in both null and spacelike directions from i(0).
