We report that an outburst of comet 29P/Schwassmann-Wachmann 1 was detected by using the images acquired with the SLT (16â Ritchey-Chretien telescope) at Lulin observatory. The outburst was observed to begin on 2021 January 14 with its brightness in V-band suddenly increasing by ~1.6 mag (from 16.6 mag to 15.0 mag), as measured through a 5.6 arcsec (10,000 km) aperture. Although the outburst event was relatively smaller than our previously reported last November (Atel #14207), the duration of two outbursts is consistent with Trigo-Rodriquezâs results (2008) who concluded that the average outburst rate is 7.3 events per year. Now, the central nuclear region was quite concentrated (https://www.astro.ncu.edu.tw/people/zylin/29P_202101.html) and the brightness might be increasing from time to time. Follow-up observations of comet 29P/S-W 1 is highly recommended.
