Caption: Figure 1.

Photometry of SN 2014J from −11d to +29d. The observations were made at Mt. Abu (JHKs) and by the LCOGT (UBVRI). The LC properties and the significant extinction of SN 2014J are discussed in Section 3. Photometric uncertainties are plotted, although there may be residual systematics due to M82 host galaxy contamination. Note that the NIR bands have not reached their secondary peaks at the final observation date in this sample.
