The compact EAS Extensive Air Shower (EAS) array (200 m2) and the Linsley method have been used with the aim to observe the primary energy spectrum. The spectral indexes αproton and αiron are obtained as − 2.46 ± 0.17 and − 3.08 ± 0.24, respectively, in the primary energy region of 1016eV − 1018.5eV in the single observation of the compact EAS array. Additionally, αproton and αiron are obtained as − 3.12 ± 0.13 and − 3.52 ± 0.17, respectively, in the same primary energy region in the observation by restricting the zenith angle of EAS events.
