“…Our estimation of the zenith angle uncertainty is in qualitative agreement with previous results, for example [27], but demonstrates different energy dependence owing to the contribution of the shower front curvature to the angular uncertainty. Only a large scale structure of zenith angle distribution of EAS event rate can be analyzed using the Yakutsk array data at angular sizes greater than 6 0 .…”

The Yakutsk array dataset in the energy interval (10 17 , 10 19 ) eV is revisited in order to interpret the zenith angle distribution of an extensive air shower event rate of ultra-high energy cosmic rays. The close relation of the distribution to the attenuation of the main measurable parameter of showers, S600, is examined. Measured and expected distributions are used to analyze the arrival directions of cosmic rays on an equatorial map including the energy range below 10 18 eV, which was previously avoided due to the reduced trigger efficiency of the array in the range. While the null hypothesis cannot be rejected with data from the Yakutsk array, an upper limit on the fraction of cosmic rays from a separable source in the uniform background is derived as a function of declination and energy.PACS numbers: 96.50.S-, 96.50.sd

“…The last event in the Table 2 is the same pair as reported in [1]. Taking into account that the systematic error in determining the energy at the Yakutsk array is 25% [6] one could say that the Table 2: Pairs of showers with the most similar properties. Here b and l are galactic latitude and longitude, respectively.…”

The highest energy extensive air showers that come one after the other in a narrow time interval and have similar galactic coordinates are analyzed. There is no significant excess in overall statistics of paired events over the random distribution. Next, the showers with the difference in arrival time up to five hours, and the difference of galactic coordinates less than 10 degrees were selected for analysis from Yakutsk EAS Array data. We found that such paired EAS events have an approximately the same characteristics: energy and the content of muons.
