  - 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.@eng
