VisualisingTheUniverse

TASOS Founder Memebr R. Kalaimani will make an interesting talk titled "ASTRONOMY IN ART" on Saturday, 6 September 2014 at The ArtScience Museum.

Synopsis
Astronomy is the oldest science, and visual arts is considered one of the oldest art forms. The thought of astronomy in art is evident to anyone who has gazed at the wonders of the night sky represented in various art forms, from the prehistoric cave murals to the awe inspiring photographs of the Hubble Space Telescope.The desire to capture and record its beauty, majesty and mystery into various media has been strong in artists in all cultures throughout the ages. The difference between the artists and the scientists has become blurred, especially in the last century. Now we have artistic scientists or scientific artists, whether they hold the brush or the digital camera. This presentation will show the historic and indispensable connection between art and astronomy.

This extremely rare event of the Transit of Venus will be entirely visible throughout most of eastern Asia, eastern Australia, and Alaska. A partial transit can be seen in progress at sunrise throughout Europe, western Asia, and eastern Africa. The transit will be Visible from Singapore on the morning of June 6.

This is a truly once in a life time event which you must not miss as the next Transit of Venus will only be in Dec 2117. Transits of Venus are among the rarest of predictable astronomical phenomena. They occur in a pattern that repeats every 243 years, with pairs of transits 8 years apart separated by long gaps of 121.5 years and 105.5 years. The last transit of Venus was on 8 June 2004. After the 2012 transit, the next transits of Venus will be in December 2117 and December 2125.

The transit of Venus starts before sunrise on June 6. The transit will be visible from singapore at Sunrise about 6.57am on June 6 and will ends at 12.49pm.

The Timing ( 6 June 2012 - Singapore Time) of Transit of Venus is as shown:


6.13 am - Ingress Exterior (No visible from singapore)
6.31 am - Ingress Interior (No visible from singapore)
6.57 am - Sunrise (Venus Transit visible from singapore after Sunrise)
12.31 pm - Egress Interior
12.49 pm - Egress Exterior (End of Venus Transit)

TASOS will collaborate with Science Centre Singapore for this event. Participants are invited to the observatory grounds to view this Transit of Venus through telescopes setup by TASOS and Science Centre Singapore. The event will open by 9.00am for all participants and the transit will be visible up to 12.49pm.

Solar Viewers and TASOS T shirts will be on sale at the Transit Venue (area just outside of the Observatory classroom) where the live video feed of the event from the large observatory will be staged. These solar viewers can be used to view the transit event and kept for future solar or solar eclipse observations. At midpoint of the transit, a short talk will be conducted at the Transit Venue for participants. We look forward to seeing TASOS members and your friends at this historic event.

Warning: Looking directly at the Sun without proper solar filter or protection would cause permanent blindness. You may view the Sun directly only through a special filter made for safe solar viewing. Never look directly through telescopes, binoculars or cameras towards the Sun without proper solar filters.

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.
