  text: In this Letter we exhibit a one-parameter family of new Taub-NUT instantons
    parameterized by a half-line. The endpoint of the half-line will be the reducible
    Yang-Mills instanton corresponding to the Eguchi-Hanson-Gibbons L2 harmonic 2-form,
    while at an inner point we recover the Pope-Yuille instanton constructed as a
    projection of the Levi-Civitá connection onto the positive su(2)+ ⊂ so(4) subalgebra.
    Our method imitates the Jackiw-Nohl-Rebbi construction originally designed for
    flat R4. That is we find a one-parameter family of harmonic functions on the Taub-NUT
    space with a point singularity, rescale the metric and project the obtained Levi-Civitá
    connection onto the other negative su(2)- ⊂ so(4) part. Our solutions will possess
    the full U(2) symmetry, and thus provide more solutions to the recently proposed
    U(2) symmetric ansatz of Kim and Yoon.
