Tuorla Observatory blazar monitoring

Optical light curves


Main characteristics


Data policy

The lightcurves shown on these pages are intended as a quick-look service for our monitoring group and for the MAGIC consortium. They are made public here to aid multiwavelength campaigns, which sometimes require quick response times. If you want to use some of the data for a publication, please do not extract the data from the images. Contact us and ask for the possibility of getting the data you need.

Data reduction procedure and intrepretation for ten (2002-2012) years of R-band monitoring data for 31 northern sky blazars are available at K. Nilsson et al. (2018, A&A, 620, 185). The main properties of the targets and observing log are available at: Strasbourg astronomical Data Center (CDS-Vizier)
