Thanks to volunteer data miner/digitizer and AAVSO member Bob Stine of Newbury Park, California, the AAVSO International Database is richer by over 3,200 historical observations of Nova Per Nr. 2 (1901) = GK Per.
The improvement to the accessible light curve for this star is both dramatic and vital, as the data which Bob digitized covers the 18 months following the outburst--from February 18, 1901 to August 8, 1902--as can be seen in the light curve shown here.
You can view a close-up light curve  of this 18-month time interval via the AAVSO Light Curve Generator.
The AAVSO is grateful to Bob Stine for his important contribution to the variable star record. Thanks Bob!
