Notes. R- and I-band peak magnitudes (Cols. 8 and 9) and duration of the impact flashes (Col. 10) observed with the 1.2 m Kryoneri telescope for the NELIOTA project. The UT date and time at the beginning of the observation (Cols. 2 and 3 respectively), the airmass (Col. 4), the selenographic coordinates (Latitude and Longitude; Cols. 6 and 7) and the lunar phase (Col. 5) are also presented. Each flash is assigned with an ID (Col. 1). The error in the selenographic coordinates is estimated to be ∼0.5 degrees. Uncertainties in the magnitudes are calculated as in Eq. (5). Impacts detected in a single frame (in both R- and I-bands) have a maximum duration of 33 msec.
