Light curves of masers and the NEOWISE W2 band detection in G24. Panel (a) displays the representative spectra of the 6.7 GHz CH₃OH (black) and 4.8 GHz H₂CO (red) maser spectra detected on 2019 September 7 with TMRT. Panel (b) presents the light curve of the WISE and NEOWISE W2 band, overlaid with the fitted long (black) and short (red) periodic curves. The best-fitting periods and their uncertainties are indicated in the top right corner, while the two arrows highlight the two peaks of 6.7 GHz CH₃OH maser variability in G24 (Wolak et al. 2019; Kobak et al. 2023). Panels (c) and (d) provide the light curves of the integrated intensity of the 6.7 GHz CH₃OH and 4.8 GHz H₂CO masers monitored with TMRT. Panel (e) contains the normalized light curves of the masers zoomed in on the time range defined by the dashed box in panels (c) and (d).
