FW: Sumbandila Missing Blog

SunSpace was established in 2000 as a spin-off from Stellenbosch University following the successful launch of SUNSAT by NASA with a Delta-II launch vehicle. During the past decade SunSpace has developed and delivered numerous satellite components, subsystems and two flight model satellite, now operational in space. This blog documents the mission of Sumbandila (funded by the DST), launched on a Soyuz-2.1b on 17 September 2009. SunSpace places a high premium on a strong partnership with the South African Government for supplying the ongoing satellite needs of our government.

Hubble Catches Stars On The Move




Source: SpaceDaily by Staff Writers, Heidelberg, Germany (SPX) Jun 03, 2010

By exploiting the exquisite image quality of the NASA/ESA Hubble Space Telescope and comparing two observations made ten years apart astronomers have, for the first time, managed to measure the tiny motions of several hundred young stars within the central cluster of the star-forming region NGC 3603.
The team was surprised to find that the stars are moving in ways that are at odds with the current understanding of how such clusters evolve. The stars in the cluster have not "settled down" as expected.

Vuurbal tref Jupiter! Kyk die video

Herman Bonnet van ASSABFN stuur hierdie nuuswenk op Spaceweather.com. Loer gerus die videos.

Photo credit: Anthony Wesley, Broken Hill Australia
JUPITER IMPACT! Amateur astronomers Anthony Wesley of Australia and Christopher Go of the Philippines have independently observed an impact event on Jupiter. The strike occurred at 20:31 UT on June 3rd and produced a bright flash of light in the giant planet's cloudtops:

"I still can't believe that I caught a live impact on Jupiter," says Go, who has made a must-see video of the event.
"There were no visible remains at the impact point for the next half hour or so, until sunrise put an end to the imaging," says Wesley.
The nature of the impactor is presently unknown. It might have been an asteroid or a comet. In either case, a dark and cindery debris field is expected to develop around the impact point; that's what has happened in the aftermath of previous Jupiter impacts. Astronomers are encouraged to monitor Jupiter, and stay tuned for updates.
Update #3: A full day has elapsed since the flash, and many observatories have imaged the impact site. So far, a prominent debris cloud has not emerged. Was this impactor too small to produce much debris? Observations will continue...
Update #2: Wesley has posted a 46 MB video of the impact on his web page.
Update #1: Anthony Wesley has pinpointed the impact site at Jovian latitude minus 16.1o, and central meridian longitudes CM1: 300o, CM2: 33.8o and CM3: 210.4o.

Komeet 81P/Wild

Hier is `n komeet in Virgo met `n magnitude van so 10 wat `n lekker uitdaqing bied vir die donker aande wat voorlê.

 Click on image to enlarge

On this night 81P/Wild is best visible between 18:30 and 01:06, with the optimum view at 21:27. Look for it in Virgo, high in the sky in complete darkness. It is easy visually in the Orion SkyQuest XT8 Dob. Use the Ultima 42mm for optimum visual detection. It is magnitude 10.5 with a diameter of 1.5'.

In the following 30 days this object is easy visually on June 6-17, with the best view coming on June 6. During this period it will fade by about 1.2 magnitudes and will reach minimum altitude of 11° on June 21.

81P/Wild will next reach perihelion in late July 2016. It is predicted to reach maximum brightness of magnitude 11.3 in mid July. The best visibility from Bloemfontein, South Africa near maximum brightness is predicted to be in mid July when it will be approximately magnitude 11.3. At that time it will be in Leo, low in the northwestern sky during evening twilight and will be detectable in the Orion SkyQuest XT8 Dob. The previous perihelion was late February 2010. Note that the magnitude and visibility of a comet can be very unpredictable.

Bortle Dark-Sky Scale

 Het jy geweet van hierdie duistere skaal? Hier is `n inliging op `n Wiki daaroor. Klik op die skakel en word wyser....
Hier is net so `n lusmaker:

The Bortle Dark-Sky Scale is a nine-level numeric scale that measures the night sky's and stars' brightness (naked-eye and stellar limiting magnitude) of a particular location. It quantifies the astronomical observability of celestial objects and the interference caused by light pollution and skyglow. John E. Bortle created the scale and published it in the February 2001 edition of Sky & Telescope magazine to help amateur astronomers compare the darkness of observing sites. The scale ranges from Class 1, the darkest skies available on Earth, through Class 9, inner-city skies.[1]

Venus en die Maan se wals

Herman Bonnet van ASSABFN het hierdie pragfoto Sondag uit sy agterplaas in Bloemfotnein vasgevang. Die aardskynsel (Earth shine) kan duidelik op die maan se verduisterde deel gesien word. Loer gerus vanaand met skemr weer. Hoewel die twee bietjie verder van mekaar gaan wees.
