In 1943, the foundation of Surlari National Geomagnetic Observatory marks the beginning of a new era in the systematic study of geomagnetic field by a continuous recording of its variations and by carrying out standard absolute measurements. Since 1998, Surlari observatory is an IMO (INTERMAGNET observatory). Over the next years, the basic equipment of the observatory has been affected by significant physical and moral wear, especially under the context of rapidly developing technologies and of the high performance acquisition process, so that the observatory was faced a growing risk not to continue to be part of the INTERMAGNET observatory network. Since March 2009, in the frame of a bi-lateral cooperation, the Helmholtz Centre Potsdam - GFZ German Research Centre for Geosciences supports the Geological Institute of Romania to upgrade its traditional and reliable observatory for the up-to-date INTERMAGNET standard. The general objective of the project consists in increasing competitiveness in order to maintain partnerships, as well as to add innovative products and services capable of meeting present and future requirements.

[en] Poleward propagating on-off switching aurorae and equatorward propagating aurorae, otherwise similar, were observed simultaneously at Rabbit Lake and La Ronge, respectively, for about 40 min before dawn of Feb 20, 1980. Rabbit Lake is a high auroral latitude site at the northern end of the Saskatchewan chain of stations for the Pulsating Aurora Campaign, whereas La Ronge, due south of Rabbit, is almost at the southern edge of the auroral zone. The repetition periods of the on-off switching aurorae are about 6 to 13 s. The poleward propagating aurorae had well defined fronts of light which extended a few hundred kilometres or more in the east-west direction. The light fronts of the equatorward propagating aurorae, though comparable in extent, were less well defined: they were thicker and fuzzier. The poleward propagating aurorae moved with a speed of approximately 10 km/s whereas the equatorward ones did so with a slightly greater velocity. Geomagnetic field fluctuations were concurrent with the aurorae at both sites. At Rabbit Lake, northward (southward) field changes were associated with upward (downward) changes, whereas the trend is reversed at La Ronge, viz., northward (southward) changes with downward (upward) changes. These trends are consistent with a model of a periodic occurrence of two line currents, westward and eastward, the former moving poleward north of Rabbit Lake and the latter approaching La Ronge from the north

[en] Complete text of publication follows. After the installation of geomagnetic observatory 'Abdus Salaam' in Sonmiani (South-west of Pakistan), Pakistan has established another geomagnetic observatory at Islamabad (33.75degN, 72.87degE), located in the North-east mountainous region of the country. Since Pakistan is spread along 23-40degN, 60-80degE, the newly established observatory will provide enhanced coverage of geomagnetic activity in the country. During 2008, repeat station work at three selected sites (Multan, Gilgit and Skardu) was also carried out to compare with the survey work previously done during 2005. All this activity was the result of collaboration between SUPARCO and IRM started in 2006 and which culminated in July 2008 by this joint installation and measurement campaign. Experiences during establishment of the observatory and repeat station comparisons/results are described in this study.
