Mr. Hirofumi Sugimoto (Japan) reported a possible strong activity of the Ursids 2016. After I received this news, I calculated the Ursids 2016 activity using worldwide radio meteor observed data from RMOB. As a result, a strong activity was observed. The peak time was around 10:00-11:00 (UT) on 22nd Dec. The FWHM had -2.0hr / +4.0hr. The activity graph is as follows:
