Cometary activity in (457175) 2008 GO98: new observations (23 Aug. 2017)
The Hilda-type asteroid (457175) 2008 GO98 has been followed-up quite closely by our facility. Our latest observations still show a clear coma, saying the cometary activity is still ongoing.
The image above is the average of seven, 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. Sky conditions were very good.
(457175) 2008 GO98, is well visible in the center of the image and shows obvious cometary activity, while the magnitude of the “head” is around 19.0, a bit fainter than in our past observations. On 3 Aug. 2017, The Central Bureaus for Astronomical Telegrams (CBAT) issued the electronic circular CBET 4418 (subscription required), publishing our observations.
Of course, we will continue monitoring this object.
