AB: The Solar Radio Burst Spectrometer (SRBS) is a project designed to 1) provide high quality radio dynamic spectra to the wider solar, heliospheric, and space weather communities; 2) serve as a development platform for ultra-wideband feeds and receivers. Dynamic spectroscopy is a powerful tool for observing radio bursts in the Sun's corona. These bursts are associated with solar flares and/or coronal mass ejections and result from coronal shocks (type II radio bursts), electron beams (type III radio bursts), and other forms of energy release in the corona. The community has been hampered by a lack of readily available dynamic spectra in the 12-24 hr UT time range, a shortcoming that has now been remedied. The instrument is located at the Green Bank Site of the National Radio Astronomy Observatory in the National Radio Quiet Zone, where the effects of radio frequency interference are much reduced compared with unprotected sites. The spectrometer is composed of two swept-frequency systems that together support observations from 18 MHz to 2 GHz with a time resolution of approximately 1 sec. The low frequency system, operating from 18-70 MHz, is a standalone dipole antenna. The high frequency system is fed by an antenna mounted at the vertex of a 13.7 m telescope and operates from 70-300 MHz; a broadband feed at the prime focus of the telescope provides frequency coverage from 300-2500 MHz. The data are available daily through a web-based interface. Both raw and background-subtracted data are available in a variety of formats. Users are encouraged to view and download selected data for research or forecasting purposes.
