(meteorobs) The decay of the GLONASS launch objects
Report time 13:00 UTC
There is as lot of excitement and confusion about the events
last night (UTC).
The European observations on Dec 01,22:30 UTC are very likely
related to the 2001-53 launch (URGAN/GLONASS). Normally the first
decayer of this mission type is the casing of the Proton DM -
stage (normally named "Platform" by SPACECOM).At this time I don't
see any "Platform" registration by SPACECOM, but the decay of the
of 3. Proton stage, generally the "number 2 on the runway".... I
think this case is clear. The "European" decayer was the casing.
2001-053D (#26990) Proton 3. stage.
SPACECOM'S FINAL REPORT - prepared Dec 02, 04:46 UTC - shows the
decay on
02 December, 04:16 +/- 07 minutes (27.0°N, 254.0°E)
on a northbound pass over Mexico.Many visual observations
from Texas shows a little bit later decay.
What can MPM + REENTRY say about this decay? In general I agree
with Alans conclusions but I see some small differences in detail.
02 December, 04:22 +/- 02 minutes (40.82°N, 263.35°E)
on the same pass over Nebraska.
With some iterations I constructed the reentry trajectory under
the assumption that the visual observations confirm the decayers below
100 km altitude.
Time (UTC) Latitude Longitude(West) Altitude
04:14 25.14° N 106.68 86.35
04:15 28.75° 104.75 82.16
04:17 32.28 102.68 76.25
04:18 35.67 100.50 67.56
04:19 38.68 98.34 53.85
04:20 40.50 96.92 34.10
04:21 40.80 96.66 18.74
04:22 40.82 96.65 10.00
It would very important to see observations from Nebraska....
