Will be updated as more information becomes available.

hh:mm:ss.s km EventNotes:
Initial detection:
13:33:50 99 - ATV faintly & intermittent visible in GV SPOSH
13:34:2194 - First acquisition from DC8 by SPOSH
13:34:24 94 - ATV is a reddish point source near horizon - first acquisition from DC8 by NIRSPEC Xybion
13:34:26 94- ATV rapidly brightening in GV SPOSH data
13:35:01 88 - Echelle spectra contain: continuum, O
Early fragmentation:
13:35:24 84 A first sign of a wake (NIRSPEC Xybion)
13:35:24 84 - start video HDTV
13:35:2684- first sign of wake (HDTV)
13:35:28 83 B fragment separates from main body, moves along side, breaks away, then fades (HDTV)
13:35:29 83- zoom in reveals multiple small fragments in wake (HDTV) small fragments continue to trail further behind main mass
13:35:35 82 - Echelle spectra: continuum, O, Na, weak N
13:35:40 82 - ATV lost in window frame by EHFRI and FROG
13:35:52 80 - Echelle spectra: continuum, O, Na, Al
13:36:02.75 78 Conset flare, emission lines
13:36:03.45 78 Donset weak flare
13:36:05.25 77D onset flare
13:36:13.45 76F onset weak flare small fragment falls below main
13:36:18.65 75G onset weak flare
Main diruption:
13:36:19.08 75 H onset disruption
13:36:19.18 75 - peak flare, cloud left behind (HDTV), tracked until 36:28 (EHFRIGV)
13:36:24 74 - Echelle spectra: continuum, N2+, Al, Na, K, O
13:36:26 74 - ATV recovered in view by EHFRI
Fragment expansion:
fragments expand (one piece low in field)
13:36:27.95 74 I onset small flare
13:36:29.95 73 J onset small flare
13:36:30 73 - main mass seen separated in two
13:36:31 73 - Echelle detects strong hydrogen emission (H)
13:36:36 72 - Echelle spectra: continuum, N2+, Al, Na, H, K, O
13:36:39.35 71 K onset small flare
13:36:40 71 - now three main fragments (HDTV)
13:36:44 70 - ATV recovered in view by FROG
13:36:45.75 70 L onset weak flare top piece
13:36:50.65 69 M onset weak flare
Disintegration of main fragments:
13:36:53.91 69 N onset bright flash on lowest of three main fragments cloud left behind, fragment falls in pieces
13:36:55.40 68 O onset weak flare middle fragment falls in pieces
13:36:57.91 67 P onset series of flares
13:37:05.65 67 Q onset weak flare
13:37:06.85 66 R onset series of weak flares
13:37:07.90 66 S onset weak flare
13:37:08 65 - Echelle spectra: continuum, Al, AlO, Na, K
13:37:13.35 64 T onset weak flare
13:37:15.25 63 U onset weak flare
13:37:17.16 63 V onset of very bright part (top fragment)
13:37:25 61 - peak luminosity
13:37:27.35 61 W two pieces in train flare briefly
13:37:30.2 60 X at front, one piece moves ahead of main, unusual color. NIRSPEC Xybion + INT1 detect strong emission lines
13:37:41 57 - ATV behind window frame by EHFRI and FROG
Full disintegration and deceleration:
13:37:46 55 Y small pieces fall below main masses
13:37:46 55 - out of FOV of window frame for DC8 SPOSH
13:37:54.04 52 Z onset weak flare
13:37:55.44 52 Z1 onset series of flares on one of forward pieces
13:38:05 48 Z2 remaining main piece falls apart in fragments
13:38:06 48 Z3 one piece overtakes rest of fragments (high in field)
13:38:19 44 - NIRSPEC gain up
13:39:08 31 - final pieces lost from view NIRSPEC Xybion
