Tonight, C/2025 R2 SWAN seems significantly brighter than 3 nights ago and probably in outbust. The ion tail is also more intense. I estimate mag 6.0 using 8x40m binoculars at 10UT on September 26. 3 nights earlier, I estimated it at mag 6.8. Attached image of C/2025 R2 SWAN taken on 2025 September 26 at 10:00UT using a Canon 6D + Sigma 200mm f/2.8 lens. iso3200 10X30sec. FOV 5 deg. North right. Cheers, M. Mattiazzo.
