During observation of the moon and Mars in the morning sky, the German astronomer Gottfried Kirch made the first telescopic comet discovery in history. This comet then possessed no tail, but two days later, Kirch noted the first traces emanating from the coma. On November 21 the tail extended one-half degree and the coma was comparable in magnitude to Regulus (magnitude 1.5). On December 4 the tail was clearly 15 degrees long and the total magnitude was 2*. Soon afterwards, the comet was lost in the sun's glare. On December 18 it was at perihelion (r=0.006 AU) and in late December the comet reappeared in the evening sky with a tail 70 to 90 degrees long and a magnitude near 2*. During this time, P.J. de Fontaney studied the comet through a telescope, noting the transparent nature and comenting on how the nucleus seemed to be absent at times. He added that when the nucleus was present it occasionally appeared multiple. By January 10, 1681 the tail had shrunk to 55 degrees and 13 days later, when the comet had reached magnitude 4*, the tail was 30 degrees long. After February 11 observations of the tail were restricted to observers with telescopes and by the 18th the tail was seen for the final time. The last observation of the comet was made on March 19, when located 2.2 AU and 2.5 AU from the sun and Earth respectively)
