1846-01D Probable nova in Aquila = CI Aquilae??
Abstract:
Kesao Takamizawa discovered an apparent nova at magnitude 10.0 in Aquila on Apr. 28.669 and 28.673 UT. This object is close to CI Aql, a possible nova discovered in 1917. Spectroscopic observations indicate it to be a fast nova a few weeks after maximum.
Justification:
CI Aql is a historical nova, and understanding new outbursts helps in studying nova phenomena.
