An 18th magnitude comet was discovered in PanSTARRS 1 images taken with the
1.8m Ritchey-Chretien on 17 August 2014. Internet reports suggest that the comet
was around 6th magnitude in late June 2015. The apparition was a poor one for
northern hemisphere observers, but it was visible in the southern hemisphere.
Willian Souza observed it as it emerged from perihelion, making it 5th magnitude with
a short tail in mid July. By early August it had faded to 7.5 and mid month it was 9th
magnitude.
