Figure \[fig:lc\_iris\] plots the light curves of ARTBs A (left panel) and B (right panel) obtained from all the three IRIS-SJIs taken in 1330 [Å]{}, 1400 [Å]{} and 2796 [Å]{}. For the ARTB A (B), the light curves show enhancements from the initial value in the intensities by a factor of more than 25(30), 60(8), and 2(1.7) in 1330 [Å]{}, 1400 [Å]{}, and 2796 [Å]{} respectively. It is noted that for A the intensity in 1330 [Å]{} filter becomes saturated during its peak. Both the ARTBs attained their peak within the 45 s (i.e., within the three time-frames) of its start and became visible nearly simultaneously in all the IRIS-SJIs (within the error of different observation times for different filters).

The light curves obtained for A and B using all the AIA channels is plotted in Figure \[fig:lc\_aia\]. As can be inferred from the plots, the intensities for both the ARTBs are enhanced by about a factor of 2 to 5 in different AIA passbands from their initial values. Both ARTBs attained their peak intensities within 36 s (i.e., within the three time-frames) of its start. Similar to IRIS, the
