TASOS President Albert Lim captured a series of photo sequence of Asteroid 2005YU55 as it races past the Earth on the night of the of 9th Nov 2011 Wednesday from his observatory from 2100hrs LT to 2330hrs LT. The Asteroid was moving East from the constellation of Pegasus from near the bright star Algenib into the constellation of Pisces. The photo attached showed the 2005YU55 as at 10.30pm local time when it was located at RA 00h 59m 16.27s and Dec +19d 21m 57.1s (J2000). This photo of the 12th magnitude asteroid was taken with a Nikon D700 with MLU at 15 secs exposure at ISO1600 through the observatory’s RC Optical 40 cm telescope on Paramount ME. The sky condition was partially cloudy and the target was blinded In the glow of the bright full Moon nearby. The asteroid was moving at very high velocity thus producing a trail even in this short 15 sec exposure. (40 cm RC focal length 2,600mm F6.5). It was moving rapidly towards the East passing North of the 10.45 magnitude bright star GSC1192:1259.

TASOS records dual occultation of bright star 13R and Hydra by Pluto on 27th June 2011

event picture event picture event picture

On the Monday evening of 27th June 2011, TASOS President Albert Lim, TASOS VP Ang Poon Seng and TASOS co-opt committee Tan Wei Leong gathered at the President’s home observatory to record these events. Wei Leong had received a late e-mail request to record these events.

The bright 13.9 mag target Star R is located at RA 18h 25m 29.010s and Dec -18d 48m 47.570s J2000 co-ordinates. The magnitude drop in Star R is expected to be 0.8 when occulted by Pluto. This first Pluto event is predicted to last a maximum of 130seconds. The predicted time of Pluto occultation is at UT 14h 17m 15s (+/- 16 secs) on 27th June 2011. A second occultation of Pluto’s small moon Hydra also occurs on the same night some 33 mins later at UT 14h 50m 23s (+/- 16 secs). The predicted duration of occultation of Hydra is maximum of 4.2 secs. This second event is challenging given the approx visual magnitude of Pluto at mag 14.0 and that of Hydra at mag 23. The Pluto starfield had first to be confirmed with the observatory’s 40cm F6.3 RC Optical on Paramount ME. It took sometime before the field was finally plate resolved and Pluto captured through Wei Leong’s QSI 583 CCD camera. A smaller field of the target was then recorded of the event through the 16 inch RC using a Flea3 camera operating at 2x2 bin, 0.5s at 2fps starting from approx UT 14h 05m through 15h 10m supposing covering both the occultation events. LT correspond to 10.05pm start capture through to 11.05pm end on Monday night 27 June 2011. 300 dark frames were taken with the Flea3 at the end of the recording session. The raw data is being Fedex by Wei Leong to NASA as requested. The result be it an event or non event will still place constraints for better future predictions we hope.

The 3 charts attached shows Pluto’s motion bottom up vertically from 26th Jun thru 27th Jun at occultation time and 28th Jun 2011. North is to the Left and East is Down on these charts and the QSI 583 CCD Image of Pluto. The target star 13R is marked on the 26th and 28th Jun charts. The 27th Jun chart shows Pluto occulting the star as to be expected.
