With all the excitement over C/2020 F8 (SWAN) don't forget that our old friend C/2019 Y4 (ATLAS) is still around in the evening twilight although the elongation is rapidly decreasing. Here is my image from May 8. My measurement of inner coma magnitude in an 11 arcsec aperture has gone up by a magnitude since last night (from 15.1 to 14.1). This comet is still doing interesting things so please keep it under observation.
