(Left) Variation in the BC/NC flux ratio of He I λλ5877,4923,4473 emission lines with time. He I λ4027 is not shown in the figure since it is of much lower S/N with its profiles from individual nights relatively noisy. (Right) Variation in the FWHM of NC and BC through the epochs for He I D3 line. The widths of both the components are anti-correlated (grey line and shaded region denotes the linear fit and its uncertainty), with the overall profile shape remaining the same with time.
