Brazilian Solar Spectroscope (BSS)

Digital, decimetric (200-2500 MHz) Brazilian Solar Spectroscope (BSS) with high time (10-1000 ms) and frequency (1-10 MHz) resolution is in regular op eration since April, 1998, at National Space Research Institute (INPE) at S ao Jose dos Campos, Brazil. BSS operates in conjunction with a 9-m diameter polar mounted antenna. It allows to select suitable observing frequency ra nge, frequency and time resolutions and data can be digitized up to 100 cha nnels. BSS has capabilities of quasi-real time display of the ongoing dynam ic spectra of the solar activity that enables the observer to modify observ ational parameters so as to suit a specific type of activity such as spikes and improve the quality of data acquisition and storage. Minimum detectabl e flux density of the spectroscope, for different combinations of the obser vational parameters, is similar to3 s.f.u. Observations are carried out rou tinely from 11 UT to 19 UT. Necessary software for data acquisition and red uctions has been developed in IDL 5.3 environment. Data are available in FI TS and ASCII formats. Absolute timing accuracy of the station is less than 3 ms. Here, we present examples of the bursts which have been recorded by B SS and available display facilities.
