Discussion:
The circle above is plotted at the expected 34 km diameter of Kotelnikov. With no positive chords we cannot say where the actual path was, so the circle has been plotted on the predicted path. A good turn out witha bright star and nicely spaced sites

Observation details for MP ( 2726 ) Kotelnikov By Star HIP HIP95967 On 2012-07-18 at 12:28:47.0 _______________________________ Observer M. Forbes Location Lower Hutt, NZ Longitude +174:58 Latitude -41:09 Altitude 25 m Datum WGS84 Telescope SCT including Cass and Mak Aperture 20 cm Seeing Slight flickering Clear Camera Type KTC530 PAL/CCIR Camera Delay 0 Timing GPS - time inserted Video with frame analysis Missed Comments: The problem was the edge of the dome was also occulting the scope (my dome has a dead spot near the zenith due to its clamshell design), so I could only just see the star. The resulting signal-to-noise is so low that I could have missed any occultation (buried in the noise). [With a mag drop of 8.5 and misses either side I think we are safe in counting this as an observed miss - jt] Report prepopulated by IOTA Reporting Add-in for OW ver.1.6 _______________________________ Observer G Hudson Location Porirua, New Zealand Longitude +174:50 Latitude -41:06 Altitude 52 m Datum WGS84 Telescope SCT including Cass and Mak Aperture 30 cm Seeing Steady Clear Camera Type WAT120N+ PAL/CCIR Camera Delay 0.07 Timing GPS - time inserted Video with frame analysis Missed Comments: No event was observed Clear sky with the star easily visible. _______________________________ Observer Graeme McKay Location Blenheim, NZ Longitude +173:57 Latitude -41:32 Altitude 18 m Datum WGS84 Telescope SCT including Cass and Mak Aperture 20 cm Seeing Steady Clear Camera Type WAT120N PAL/CCIR Camera Delay 0.33 Timing GPS - other linking Video with frame analysis Missed Comments: _______________________________ Observer Peter Graham Location Martinborough, New Zealand Longitude +175:29 Latitude -41:14 Altitude 73 m Datum WGS84 Telescope SCT including Cass and Mak Aperture 25 cm Seeing Steady Clear Camera Type WAT120N PAL/CCIR Camera Delay 0.03 Timing GPS - time inserted Video with frame analysis Missed Comments: The star/asteroid was visible the whole time but the light curve fails to show any detectable sensible variation in magnitude. _______________________________ Observer John Talbot Location Waikanae Beach, NZ Longitude +175:01 Latitude -40:51 Altitude 5 m Datum WGS84 Telescope Newtonian Aperture 25 cm Seeing Slight flickering Broken cloud Camera Type KPC-350BH PAL/CCIR Camera Delay 0 Timing GPS - time inserted Video with frame analysis Missed Comments: Wind and cloud affected but star visible for 2 min each side of predicted and no event.
