Space weather can be monitored from the ground (astronomic/astrophysics observations and geomagnetic observatories) and from space (satellite data).
Optical instruments (telescopes on the ground) recording the number of sun spots, as well as to viewing aurora, but these observations are affected by the weather from Earth's atmosphere. Observation from space does not have such a limitation. In the last years,satellites and spacecraft have monitoring the space weather. Through cooperationbetween European Space Agency (ESA) and National Aeronautics and Space Administration (NASA), was launched (in 1995) Solar and Heliospheric Observatory (SOHO) for study solar wind and the internal structure of the Sun.
The phenomena from the Sun, such as the sun spots, solar flares, the intensity of x-ray
and ultraviolet radiation, provide good indications about space weather. All of these
provide valuable information for space weather forecasting.On the other hand, geomagnetic observatories from Earth?s network INTERMAGNET provide the on-line three-axial monitoring of geomagnetic field.In this paper we conducted a study on the geomagnetic storm with apex in March 17,2015, which had a special character compared to others. It debuted suddenly on March17, continued until 20, returned to magnetic calm values on the 21, after which it had a new increase on the 22 and returned to calm values starting with 23 March.For the period March 16-23, 2015, we analyzed the geomagnetic data (provided from INTERMAGNET) from 5 observatories located at very different latitudes and latitudes on the terrestrial surface, as well as the data provided by GFZ Potsdam and NOAA (https://www.spaceweatherlive.com) on three-hours indices of geomagnetic activity.This study, presented in paper will be a part of a comprehensive report from the project:Development of capacities and services for research and forecasting of space weather (SWE), that is part of the complex project: Institutional capabilities and services for research, surveillance and forecasting of risks from extra-atmospheric space (SAFESPACE), funded by UEFISCDI Romania.
