Observers: 1(M) D Herald,Murrumbateman, NSW,AU 2(M) J Broughton,Reedy Creek, QLD,AU 3(M) C Chad,Gunnedah, NSW 4(P) Prediction, 9 Feb
Discussion:
The circle above is plotted at the expected 200 km diameter of Metis. With no positive chords we cannot say where the actual path was, so the circle has been plotted on the predicted path.

Observation details for MP ( 9 ) Metis By Star UCAC2 42042927 On 2013-03-15 at 09:49:19.0 _______________________________ Observer Dave Herald Location Murrumbateman, NSW Longitude +148:59 Latitude -34:57 Altitude 594 m Datum WGS84 Telescope SCT including Cass and Mak Aperture 40 cm Seeing Steady Clear Camera Type WAT120N+ PAL/CCIR Camera Delay 0.11 Timing GPS - time inserted Video with frame analysis Missed Comments: Report prepopulated by IOTA Reporting Add-in for OW ver.1.7 _______________________________ Observer John Broughton Location Reedy Creek, QLD, AU Longitude +153:23 Latitude -28:06 Altitude 66 m Datum WGS84 Telescope SCT including Cass and Mak Aperture 25 cm Seeing Slight flickering Thin cloud < 2 Camera Type WAT120N+ PAL/CCIR Camera Delay 0.19 Timing GPS - time inserted Video with frame analysis Missed Comments: Variable atmospheric transparency caused significant variations in the lightcurve that required normalisation with a comparison star. As with any occultation of small magnitude drop, short-duration events can't be discriminated from background noise. In this case, I can rule out durations longer than 3.2s (<=3.2 is an unlikely duration compared to the 16.9s expected maximum). _______________________________ Observer Chris Chad Location Gunnedah, NSW Longitude +150:15 Latitude -30:59 Altitude 315 m Datum WGS84 Telescope Newtonian Aperture 25 cm Seeing Steady Clear Camera Type Samsung SCB-2000 NTSC/EIA Camera Delay 0 Timing GPS - time inserted Video with frame analysis Missed Comments: Nothing apparent in the data. Used Occular without any convincing results. Plausible that any event had a brightness drop too small to detect with my system. 2nd station failed due to recorder failure Report prepopulated by IOTA Reporting Add-in for OW ver.1.7
