A/2017 U7 This object traveled its perihelion 6.42AU on September already, but so far distance, it can be observed same condition like this. It seems a faint tail can be seen south-east direction. I estimate its magnitude m1=16.0 from UCAC-4. The image is not fine because in low declination. 2019.10.26.41392UT, 6*60s, 45cm F4.6 Reflector, FLI ML8300, 2 bin, 1/2 cropping, take in Nagano pref., Japan by Kunihiro Shima. |
