In my decidedly unsystematic "looking for satellites" sessions, I've seen
23907 (= 96-029B = NOSS 2-3 R/B) on two evenings this year ...

   UTC Date        App.Mag  Quicksat Intrinsic Mag (@1000 km, 0 phase)
1997 02 09/23:56    V=2.3   IM=+2.4 Varying Period about 2.5s
1997 03 07/23:58    V=1.7   IM=+2.2 Steady
1997 03 07/23:59-   V=1.3   IM=+2.0 Steady

Alas, nothing more recent (nor, I must stress, have I looked for it).

Currently, based on the same old elements, I expect no good passes in the
next few days (just an 11 degree high pass tomorrow evening and a 5 degree
pass Tuesday evening).

Sorry.

Clear and dark skies!
