Comet overglow observed the 13rf of July
The comet showed an increased brightness of about one magnitude in the 13rd of July night. Despite the moon presence, the comet was visible with naked eyes. A noticeable extension of the coma is clearly visible, certainly due to a possible fragmentation of the comet.
In the same time, Christian Buil was recording comet spectra, with the prototype of what will the Spectr'Aude.
