Coronal mass ejection (CME) is one mysterious property of the sun. Practically studying CMEs directed to earth, known as Halo CMEs is very important since these CMEs can affect space weather around the earth and cause major problems to human activiti

Pulsar is a highly magnetized rotating neutron star. It continuously emits a wind of relativistic electrons and positrons. This wind creates an electron-positron-cloud around the pulsar. This cloud, which is full of relativistic electrons and positro

Journal of Atmospheric and Terrestrial Physics. 51:529-531
Some sources of errors when using the Obolensky filter method for space charge measurements have been studied. No influence of disturbed lines of forces of the atmospheric electric field caused by a grounded instrument was observed. Under unfavourabl
