29P/Schwassmann-Wachmann - 2025-05-15 (passing through Leo) Sun Distance 6.28 AU (receeding slowly) Earth Distance 6.22 AU (930.8 million km) A stellar like object is visible at the forecast position of the comet but there is no star object at this location in Aladin. It would seem that the comet is having a new outburst Measured Magnitude +14.10 (Clear Filter) |
