I captured the C/2020S3 Erasmus in lower southeast dawn skies. The 8th magnitude coma positioned in the western edge of Corvus, about a degree northeast of η Crt. And you can detect a thin and dimmed dust tail stretched in west direction. The elevation of comet was only 20 degrees. Although the comet will brighten up to 7th magnitude in the end of November, the condition get worse because the comet closes to the sun.
  View angle: 0.70×0.70°
