Follow-up {\\it Swift-XRT} observations revealed three flaring episodes through March 2018, and the peak X-ray flux is about $10^3$ higher than the {\\it ROSAT all-sky survey (RASS)} flux upper limit. Optical spectral measurements taken by the {\\it Magellan 6.5-m telescope} and the {\\it Lick-Shane telescope} both show a largely featureless spectrum, strengthening the BL Lac interpretation first proposed by \\citet{Bruni18}.
