Discovery
D. J. Martinoff (Engelhardt Observatory, Kazan, Russia) found this "comet-like object" on a plate exposed for P/Brooks 2 on 1946 October 20.92. The object was described as diffuse, without a central condensation, and exhibited a slight tail. The magnitude was estimated as 12. The object was not found on the plate until the end of October, and Martinoff said it could not be verified because of bad weather.
Positions
Analysis
Martinoff requested verification on November 1. On November 5 and 6, H. L. Giclas (Lowell Observatory, Arizona, USA) used the 33-cm photographic telescope to search for this object. Two photographic plates covering an area of 160 square degrees were exposed. The first was centered 2° north of P/Brooks 2 and possessed a limiting magnitude of 14, while the second was centered on a declination of +25° and possessed a limiting magnitude of 16. No comet-like objects were found, although 24 asteroids were located, the faintest being magnitude 14.2..
