Which nova is this?

This paper from 1937 has observations of "Nova Lacertæ 1936":
http://cdsads.u-strasbg.fr/abs/1937JO.....20..120L

I only find one nova in Lacerta for 1936: CP Lac. If I plot the light curve of this one, it looks like it was discovered June 1936.

But the observations from Lagrula start in february and end in september.

Where dit it (or he?) go wrong?

The July-September

The July-September observations quite fit the AAVSO visual light curve, so I assume they were "Fevrier" observations we made in June. Probably it was a typo. I doubt they were prediscovery observations, especially since two days before the discovery CP Lac was fainter thatn 13pg. (P.P.Parenago, Perem. Zvezdy 7, N3, 109, 1949.)

Merry Xmas,

Robert

Thanks! Now that you mention

Thanks! Now that you mention this, it seams obvious it is just a typo....

His observations are not included in the database. I would like to add them, but have no info about the filter used (unfiltered?) or which comparison star(s) he used for each observation.

Are there already other observations from Lagrula in the database (is there somewhere a list available with observer - observerinitials)?

These are photographic (pg)

These are photographic (pg) observations. Mpg is usually blue mag, the closest is the B band, but not the same. Historically they were included as "pg" in the AAVSO database. The comp stars were listed on the table "Etoiles de comparaison".
