Near-Earth Asteroid 2014 UF56 is approaching: an image (26 Oct. 2014)

Near-Earth asteroid 2014 UF56: 26 Oct. 2014

Near-Earth asteroid 2014 UF56: 26 Oct. 2014

While waiting for the near-Earth asteroid 2014 UF56 and its very close encounter later today, we imaged this small, ~14 meters rock 24 hours, while it was already within one million kilometers.

Above is a single 180-seconds exposure, remotely collected with the  PlaneWave 17″+Paramount ME+SBIG STL-6303E robotic unit part of the Virtual Telescope Project. The telescope tracked at the fast apparent rate of the asteroid, 30″/minute, so the object looks like a sharp dot of light, while stars are leaving long trails.

The Virtual Telescope will show asteroid 2014 UF56 live on 27 Oct. 2014, at 19:00 UT on its webTV here!

Near-Earth Asteroid 2014 SC324: an exceptional movie

Near-Earth asteroid 2014 SC324: min vs max brightness (25 Oct. 2014)

Near-Earth asteroid 2014 SC324: min vs max brightness (25 Oct. 2014)

Last night, at Virtual Telescope we tracked the near-Earth Asteroid 2014 SC324, sharing it with our followers online, in real time.

In particular, on 25 Oct. 2014, we managed to collect 110 images, back to back, covering the 00:12 to 00:42 UT (30 minutes). This ~60 meters large asteroid showed evident variations in brightness suggesting it was a quite elongated body. A first guess suggests an amplitude of 1.5 magnitudes.

The animation above alternates the max and minimum brightness, showing the full amplitude at a glance. Images were carefully adjusted so that the variation you see is just real.

Understanding that variation is easy: the asteroid is rotating and, because of a very elongated shape, it is changing during rotation the amount of light it is reflecting to us. The larger the amplitude, the stronger the elongation (in principle, darker/brighter areas on the asteroid could do the same, independently from the shape). Things can be of course much complicated (as for non-principal axis rotators), but that is the key point.

Of course, the apparent luminosity changes smoothly if you consider a continuous coverage and it can be better seen in the video below, showing all the available 110 frames. NB: a larger (16Mb) version is available here. We are working to extract useful data from these observations.

Near-Earth asteroid 2014 SC324: a spectacular close encounter – image and podcast

Near-Earth Asteroid 2014 SC324: 24 Oct. 2014

Near-Earth Asteroid 2014 SC324: 24 Oct. 2014

Once again, an asteroid was the “star” of our live, online activities. This time, it was the near-Earth asteroid 2014 SC324 coming as close as about 550.000 km on 24 Oct. at 19:21 UT. While it was not at all a risk for our planet (and this was of course well-known), this 60-meters large asteroid made a spectacular apparition, perfectly accessible from the northern hemisphere.

We planned a live, online coverage of this fly-by, sharing it with the community. It was a great success: during the event, we captured many images, showing also the large brightness variations of light of the asteroid, around 1.5 magnitudes, suggesting a very elongated shape. Data will be further analyzed to get an estimate of the rotational period.

Meanwhile, above is an image coming from a single 60-seconds exposure, remotely collected with the  PlaneWave 17″+Paramount ME+SBIG STL-6303E robotic unit part of the Virtual Telescope Project. The telescope tracked the apparent, fast (200″/minute) rate of the asteroid: so, 2014 SC324 is visible as a sharp and bright dot of light in the center, while stars are trailing. At the imaging time, the object was at about 580.000 km from the Earth, on its way back.

Below is the podcast of the live event.

Near-Earth Asteroid 2014 SC324 getting close: a image (23 Oct. 2014)

Near-Earth Asteroid 2014 SC324: 23 Oct. 2014

Near-Earth Asteroid 2014 SC324: 23 Oct. 2014

Less than 24 hours before its close approach, at Virtual Telescope we imaged near-Earth asteroid 2014 SC324 while it was peaking in brightness at magnitude 13.5.

The image above is a single 300-seconds exposure, remotely collected with the  PlaneWave 17″+Paramount ME+SBIG STL-6303E robotic unit part of the Virtual Telescope Project. The telescope tracked at the apparent, fast (75″/minute) rate of the asteroid. 2014 SC324 is visible as a sharp and bright dot of light in the center, while stars are trailing. At the imaging time, the object was at about 920.000 km from the Earth

Next 25 Oct. at 00:00 UT at Virtual Telescope we will show this very close approach live, online, for free: save the date!

Near-Earth Asteroid 2014 SC324 coming close: a image and video (20 Oct. 2014)

Near-Earth Asteroid 2014 SC324: 20 Oct. 2014

Near-Earth Asteroid 2014 SC324: 20 Oct. 2014

While waiting for the live event covering this object, we observed the near-Earth asteroid 2014 SC324 on its approaching route. Late this next 24 Oct., this 60-meters large object will “touch” a minimum distance of about 570.000 km from us, that is 1.5 lunar distances. Needless to say, it is an absolutely safe distance, no risks at all for the Earth. It will be a wonderful opportunity for all of us to look at this asteroid.

A few hours before of the fly-by, it will be as bright as magnitude 13.5, so easily within the capabilities of a small photographic equipment: so, amateur astronomers, stay tuned! It will be perfectly placed in the sky, especially for those living in the northern hemisphere.

The image above is the average of three, 180-seconds exposures, remotely collected with the  PlaneWave 17″+Paramount ME+SBIG STL-6303E robotic unit part of the Virtual Telescope Project. The telescope tracked at the apparent rate of the asteroid. 2014 SC324 is visible as a sharp dot of light in the center, while stars are trailing.

Below a video is available, showing four images taken back to back during the the same session: the asteroid is a sharp dot of light in the  center, tracked by the mount, while stars are trailing on the background. Click on the image for the full res version.
