The flux from distant type Ia supernovae ( SN ) is likely to be amplified or de-amplified by gravitational lensing due to matter distributions along the line-of-sight . A gravitationally lensed SN would appear brighter or fainter than the average SN at a particular redshift . We estimate the magnification of 26 SNe in the GOODS fields and search for a correlation with the residual magnitudes of the SNe . The residual magnitude , i.e . the difference between observed and average magnitude predicted by the “ concordance model ” of the Universe , indicates the deviation in flux from the average SN . The linear correlation coefficient for this sample is r = 0.29 . For a similar , but uncorrelated sample , the probability of obtaining a correlation coefficient equal to or higher than this value is \sim 10 \% , i.e . a tentative detection of lensing at \sim 90 \% confidence level . Although the evidence for a correlation is weak , our result is in accordance with what could be expected given the small size of the sample .
