Auf der comets mailing list wurde ein Ausbruch um ein mag angezeigt . Der Komet steht in den Fischen, ist 2°° MESZ niedriger als 10° und ist von weiten Teilen Deutschlands aus ein schwieriges Ziel. Vor dem Ausbruch hatte der Komet etwa 13 m, es sind alse im Moment etwa 12m.
Hi all,

Based on just 2 Zwicky Transient Facility g-band images from the last
week, it appears comet 29P has outbursted again. Differencing the two
images shows a moderately strong point source component, suggestive of
an outburst. Quan-Zhi Ye measured photometry within a 20,000 km
radius aperture (4.5") for confirmation:

Date (UT), g (mag)
2019 Jun 9.46, 17.42
2019 Jun 12.45, 16.54

The g-band magnitudes are calibrated to the PanSTARRS DR1 catalog.
Sorry for the delay, but with only two images, we wanted to be sure of
our results.
