Report time 09:20 UTC
In addition to Alans and Robs calculations I have also looked for the possible
reentry of 1989-096C (#20354) Granat R/B with an updated version of SpaceComs
MSGP 4 program: Here the relevant figures:
July 25 Time(UTC) Altitude(km) Latitude Longitude
16:08 278.1 15.46°S 88.94°E
16:09 76.5 11.19°S 92.13°E
16:10 - 98.2 06.61°S 95.43°E
The sun is well below under the horizon. The decay area is over the Indian
Ocean SW of Sumatra.
1999-036B (#25848) SL-6 R/B 1:
The last update from SpaceCom - prepared July 23, 06:43 UTC - forecasted the
decay at July 23, 18:55 UTC +/- 09 hours (62.0°N, 187.4°E)
MPM shows with the ELSETs 99203.793...and 99204.160... a decay at
July 23, 19:05 UTC +/- 90 minutes (36.7°N, 236.8°E)
This last descending pass shows with SpaceCom a decay area around the Bering
Street. My MPM prediction shows a possibility that the R/B crossed California
around San Francisco during decay.
An update will follows with the next released ELSETs.
