No further elsets were published for #24291, Microsat, since my posting
yesterday. My decay analysis remains unchanged, that decay occurred at
Nov 12 18:45 UTC +-2h near 41.5 deg N, 25.4 deg W, while it was heading
NE-wards over the Atlantic, to the SW of Ireland. If it survived, it
would have crossed the UK from N Ireland (18:49 UTC) to Edinburgh
(18:50) and onwards to Oslo, Norway, (18:52) and N of Stockholm, Sweden,
at 18:53. It is unlikely to have survived much beyond the next
northbound crossing of the equator near 71.2 deg W at 19:59, just beyond
SpaceCom's decay point, but if it did there was another eastbound pass
over N Europe from Trondheim, Norway, at 20:20. Edinburgh was under an
overcast sky at the critical time. My SatEvo-predicted elset for the
final equator crossing:
MicroSat         1.0  0.0  0.0  8.3 d 0.37       115 x 107 km
1 24291U 96050A   99316.77320022 3.02242249  50000+2  75984-3 0 99774
2 24291  62.7373 280.4432 0006103 304.1373  55.8048 16.61011829176977

My updated prediction for the decay of #4222 ( 69- 97 B = AZUR Scout
rocket) is practically unchanged at Nov 15 08:05 +-12h, more than 12
hours before SpaceCom's current estimate.
