Title

Possible cometary activity of 2017 TW13 2017 TW13 (YTBE6EF) is an unusual object on a cometary orbit (q = 2.0 au, inclination 45 degrees, period 19 years). I recovered it a week ago and found a coma, and a hint of tail northwards today. Now it is around 18 mag, 2mag brighter than predicted. The position was about 20" off from the ephemeris by mpc.
