Vanguard 1 (5/58002B) is making perigee morning passes near lat 34N.
At 1129 UT (0429 local) on 5/17 it was glimpsed in an 11.4 cm (4.5 in)
newtonian scope using a 10mm eyepiece, giving approx. 90 power.  The
slant range when it was seen was 890 km (553 sm).  The phase angle
and sky transparency were both very good, which helped negate the
glow from a 3rd quarter moon.  The magnitude was between 9.5 and 10,
very close to Skymap 6.2's magnitude 9.4 prediction.
