We report the result of an extensive photometric follow-up of ASASSN-13aw (ATEL#5183) aka SN 2013dr,
classified as type Ia supernova (Tomasella et al., CBAT TOCP for PSN J17193026+4742046).
The telescopes involved in the follow-up operated in the preparatory mode for the forthcoming Gaia Science Ale$
The photometric data were collected with a range of telescopes, instruments and filters, but were
all calibrated to common pass bands of B,V and r,i using APASS all-sky star catalogues (Henden et al.2009).
The light curve contains about 150 data points and covers a range of about 30 days.
It is available here: http://www.ast.cam.ac.uk/~wyrzykow/ASASSN-13aw_followup.pdf
Using a simple parabolic fit to the r-band light curve we obtain the peak MJD of 56491+-3.
The revised coordinates of the supernova are RA,Dec(J2000.0)= 17:19:30.10, 47:42:03.40.
The photometric calibrations were obtained using
the Cambridge Photometric Calibration Server (CPCS), designed and maintained by Sergey Koposov
and Lukasz Wyrzykowski.
