MAGIC daily integral ULs from the direction of SN 2014J for energies above 300 GeV (red circles) and 700 GeV (blue squares). The integral UL for energies above 700 GeV was not computed for the first night (MJD 56 684) due to low statistics (see also Table 1). The horizontal black dashed line indicates zero flux level and the vertical green line indicates the day of the SN explosion (MJD 56 678), just six days before the beginning of the MAGIC observations.
