Russell Eberst has reported a single observation of a bright, quasi 55 deg
satellite that may be OTV 5:

I offer the following search elements:

1 77201U 77201A   17276.17214120  .00000000  00000-0  00000-0 0    08
2 77201  55.9600 324.3919 0010000  59.9036  43.0917 15.71345000    08

1 77202U 77202A   17276.17214120  .00000000  00000-0  00000-0 0    00
2 77202  55.3600 326.6902 0010000  62.8533  39.3644 15.48005000    07

I doubt it is much lower in altitude than the 77201 orbit or much higher
that 77202.

Please do not be misled by the high precision to which the elements are
stated; that is the result of my efforts to constrain the orbit close to the
expected launch plane. The inclination and RAAN could be off by a few
degrees.

It is recommend to use wide field optics, or on favourable passes, the
unaided eye. Avoid observing close to the predicted intersection with
Earth's shadow.
