Abstract
We have investigated 49 solar macrospicules observed in 2010 at the rising phase of the solar cycle at high (circumpolar) and low (near the solar equator) latitudes. We have found that, within the measurement accuracy, the macrospicule birth rate does not depend on the latitude and is \({\sim}0.1\) deg\({}^{-2}\) h\({}^{-1}\). Concurrently, we have established that the mean heights of macrospicules near the equator and the poles differ noticeably. After the elimination of projection effects, we have obtained \(31.7\pm 0.2\) thousand km for macrospicules at low latitudes and \(39.1\pm 0.3\) thousand km for high-latitude macrospicules.
