We present a new method for automatic detection of flare events from images in the optical range. The method uses neural networks for pattern recognition and is conceived to be applied to full-disk Hαimages. Images are analyzed in real time, which a

First 405 GHz and 212 GHz solar flare observations were obtained during short campaigns while the new solar submillimeter-wave telescope (SST) was still undergoing adjustments at the CASLEO El Leoncito observatory in the Argentina Andes. We show here

We report accurate new wavelengths for 29 mid-infrared ionic fine-structure lines, based on observations with the Short Wavelength Spectrometer (SWS) on board the Infrared Space Observatory (ISO). Our results originate from observations of NGC 7027,

During two Freja passes over auroral arc systems special wide-angle CCD cameras were operated from the ground. Comparisons of the optical observations with satellite-measured plasma parameters are performed. Motions of fine structures of the arcs are

During a nine day observational campaign in February 1992 we used an image-intensified CCD TV camera along with the EISCAT radar to observe auroral arcs in the magnetic zenith above Kiruna. We determine the normal motions of auroral arcs near magneti

During a campaign in January 1988 we observed auroral arcs with the EISCAT UHF radar system and a low light level TV camera. The aim was to compare apparent motions of the arc and its small scale structures with plasma motions in the adjacent F-regio

The paper reports data received from the Freja satellite during two passes over broad auroral arc systems or inverted-V events above Gillam/Manitoba when special wide-angle CCD cameras were operated at this location in addition to the CANOPUS network

The constituents of the cosmic IR background (CIB) are studied at its peak wavelengths (100 and 160 um) by exploiting Herschel/PACS observations of the GOODS-N, Lockman Hole, and COSMOS fields in the PACS Evolutionary Probe (PEP) guaranteed-time surv
