ALMA, Atacama Large Millimeter/submillimeter Array showed us something on the dark lane at the center of Centaurus A in 2012. Eastern half (or left half on the frame) was coming toward us, and western half was moving away from us.

Equipment: Takahashi FSQ-106ED, F3 Reducer 0.6x, and Canon EOS 5D mk3-sp4 by Seo-san on Takahashi EM-200 Temma 2 jr. autoguided with Fujinon 1:2.8/75mm C-Mount Lens, Pentax x2 Extender, Starlight Xpress Lodestar X2 Autoguider, and PHD Guiding 2

The frame, 4,056 x 2,437 pixels is cropped of the original, 5,760 x 3,840 pixels, and it is comparable to a frame taken with a scope of the focal length about 400mm.

Exposure: 3 times x 22 minutes, 5 x 4 min, 4 x 1 minute at ISO 1,600 and 320mm f/3.0

site: 2,674m above sea level at lat. 24 37 43 South and long. 70 13 45 West near Cerro Armazones in Atacama Desert Chile

I tried imaging of the object, though the imaging condition was not so good yet. North is up, cropped a little. The left upper corner of the frame is around 16h56m28s +64 06 52, and the right lower corner is around 16h16m13s +58 47 43 according to the planetarium software in my PC.

The altitude of the object was low about 14 degrees in the north east at moonrise. We can view some amount of IFN, integrated flux nebula in the area.

Something faint and elongated vast object looks to be visible near the ephemeris on the frame, though I can not confirm it the remnant of the comet. I feel that I may be able to confirm it following the movement of the object in coming days. If it was mere some kind of ghost which I might have made during the extreme emphasis in processing of the frame, I must be unable to see it again on the following images. If it was the real ghost of the comet, I must be able to see it again at different location near the ephemeris at the time. I am planning the follow-up observation during this stay in Hawaii.

equipment: Leica Apo-Elmarit-R 180mmF2.8 and Canon EOS 5Dmk2-sp2, modified by Seo-san on Takahashi EM-200 temma 2 jr. equatorial mount, autoguided at a star with Takahashi FSQ-106ED, reducer QE 0.73x, hiro-design off-axis guider, Starlightxpress Lodestar Autoguider, and PHD guiding

exposure: 2 times x 1,560 seconds and 3 x 1,200 seconds at ISO 1,600 and f/4.0
The first exposure started at 13:01:08, and the last exposure started at 15:09:41 December 29, 2013UTC. The moonrise was 13:53UTC at the site.

site: 11,000 feet above sea level near Mauna Loa Observatory in Hawaii

# update at 1:39 December 31, 2013UTC: It was reported that the sausage-like faint object was visible on DSS. I thinks it not the remnant of C/2012 S1 but a part of integrated flux nebula. #
