As part of our blazar monitoring campaign, SMARTS observes southern blazars and blazar candidates that appear on the public Fermi Large Area Telescope (LAT) monitored source list (http://fermi.gsfc.nasa.gov/ssc/data/access/lat/msl_lc/).
Relative aperture photometry of target PKS 0502+049 (RA=05h05m23.18s DEC=+04d59m42.72s, J2000, redshift z=0.954) was performed in B, R, and J bands between UT Mar 14 2015 and UT Mar 23 2015 with the SMARTS 1.3m+ANDICAM instrument located at Cerro Tololo InterAmerican Observatory in Chile. We report that this source increased in brightness by delta_B=3.1 mag, delta_R=3.2 mag, and delta_J=3.2 mag. This source was last reported to be in a flaring state in March 2013 (Atel#4858, Atel#4868).
The optical and infrared errors on differential magnitudes are estimated to be about +/- 0.02 mag.
Further multi-wavelength observations of this flaring source are encouraged.
