Week in Space Data, every Friday.
TIP message of 3 Nov, 11:32 UTC.
Between 05:47 and 15:47 UTC on Wed 4 Nov
Predicted 10:47 UTC, plus or minus 5 hours.
Window opens in about 10 hours.
That window spans about 7 orbits, so it could come down anywhere along about 7 laps of its path, between about 20.5°S and 20.5°N.
Space-Track update of 3 Nov, 11:32 UTC. Next update expected in about 3 hours.
Between 05:47 and 15:47 UTC the object makes about 7 laps between about 20.5°S and 20.5°N. The shaded band shows the latitudes it passes over. It could come down anywhere in this band, or burn up entirely.
Latitudes it passes over (about 20.5°S to 20.5°N)
Only the latitude band is shown: paths computed from the latest orbital elements did not match the prediction closely enough to draw. Map: Natural Earth (public domain), equirectangular.

The bars (wider screens) draw each window on one time axis, with a tick at the predicted time. The window is read as plus or minus that many minutes; Space-Track's documentation does not define the unit, so we cross-check it against NASA and ESA (see How we read these predictions).
