Visibility I / V
29P / (Schwassmann-Wachmann) The periodic comet of the Jupiter family was filmed on the second night of the November 2021 campaign. Outbreaks sometimes occur in a comet, which is why we have tried to shoot several times. The comet's orbit is outside Jupiter's orbit and will be close to Jupiter 2037 less than 1au away. Discharges may increase the brightness by 1-5 mag. The size of the large comet's core is 60.4km. As of filming, the comet was 5,064 miles away, the closest 4.82au on November 6, 2020.
1Picture The sum of the stack by comet. In the direction of 3 o'clock a separate protrusion and a small tail pointing in the direction of 7 o'clock are shown. A large coma is visible due to recent eruptions.
