英文摘要The perihelion of long-period comets places them near the Sun so they may exhibit activity. Before 2013 LU28 reached its perihelion, we performed a continuous observation to detect possible activity. Using the Lijiang 2.4 m telescope with a Johnson R filter, we measured the brightness of 2013 LU28 from 2024 January 3 to April 13. The instrumental magnitudes were subsequently transformed into the Pan-STARRS r system. Due to the noticeable descending trend in the absolute magnitude, we verified the cometary activity and constrained some photometric properties of 2013 LU28. Consequently, the increased cross-sectional area had a rate of 42.8 km(2) day(-1), and the corresponding mass-loss rate was 2.64 kg s(-1) with the assumption of a dust-particle size a=10 mu m and the density rho = 400 kg m(-3). We estimated the nucleus radius as 0.11 less than or similar to r(n) less than or similar to 0.21 km for CO sublimation and 0.20 less than or similar to r(n) less than or similar to 0.71 km for CO2 sublimation and the grain size of 2013 LU28 was a(c) similar or equal to 117.95 mu m for CO and a(c) similar or equal to 7.57 mu m for CO2. The long-term observations provided in this paper will offer significant value for investigating the mechanisms driving the activity of 2013 LU28.
