Max Altitude from Horizon 21 degrees. A little less than two weeks after perihelion and Earth's MOID. Same-Same, subjectively beautiful. From August 15 orbital trail clearly present in subframes . Dust tail extending to the 2 o'clock pos. Measured brightness at 7.8 mag without suitable comp. stars. As usual, color calibration was performed with PixInsight's SpectrometricColorCalibration process using a white balance of the spectral class of our sun as reference.
