 | | For this, I worked closely with the German astronomer Hans-Emil Schuster and his night assistants, the brothers Guido and Oscar Pizarro from Chile, who did the original exposures at La Silla, as well as with the laboratory staff, including Bernard Dumoulin, Françoise Patard, Bernard Pillet and Jean Quebatte. |
 | | This plate was taken by Guido Pizarro on 24 September 1975, so I searched some other plates obtained a month earlier. |
 | | But then, incredibly, there it was: another, much fainter, trail right in the corner of a plate taken by Oscar Pizarro on 10 August. |
