Cometary activity in (457175) 2008 GO98: follow-up image (27 July 2017)
After a few days, we imaged the intriguing (457175) 2008 GO98, the Hilda-type object again, to check if its cometary activity was still ongoing. And it was, of course, as this image clearly.
The image above is the average of nine, 180-seconds exposures, remotely taken with “Elena” (PlaneWave 17″+Paramount ME+SBIG STL-6303E) robotic unit available at Virtual Telescope. The image scale is 1.2″/pixel.
(457175) 2008 GO98, sitting in the center of the image, is still clearly showing cometary activity, while the magnitude of the “head” is around 18.8. Compared to our 21 July 2017 and 17 July 2017 observations, we see that the activity is basically unchanged.
Needless to say, we will continue monitoring this object to learn more about its behavior.
