D. 1. Using a search ephemeris published by Zweck, A. A. 03. It was described as stellar and, with a magnitude of 12, it was 2 magnitudes brighter than expected. The object was confirmed by L. E. 25, who described it as perfectly stellar, with a magnitude of 11. Cunningham was at once suspicious of the object and calculated a circular orbit based on his two positions and found a very close agreement with the asteroid Nysa (44). A comparison with the predicted position and 17 catalog of comets motion of that asteroid immediately confirmed this finding and the search for P/Schwassmann–Wachmann 2 continued.
