    Here is a rough estimate I cobbled together from various sources, which I intend to be used only to assess visibility
    1 79050U          12044.45493056  .00000000  00000-0  00000-0 0    01
    2 79050  69.4990 238.7700 0002498 100.5250  75.6290 12.52000000    02
    Based on the object's size (0.364 m dia.), I estimate standard visual magnitude of 10.6 +/- 1 (1000 km, 90 deg phase
    angle), which will make it difficult to spot in its 1450 km orbit.
