The second apparition was calculated for 1938, but Gale failed to find it; however, it was recalculated by Leland E. Cunningham who later recovered it for that year.
The 1949 apparition was never detected, and due to unfavourable conditions ever since it has never been recovered and it remains a lost comet.
