[69.04] Recent Results from the Birmingham Solar-Oscillations Network (BiSON)

The Birmingham Solar-Oscillations Network (BiSON) consists of 6 semi and fully automatic observatories, dedicated to the collection of low-degree solar oscillations data in integrated sunlight. The network was established in 1981 with two permanent stations; the addition of several more sites culminated with the addition of a sixth in 1992.

Here, we give an update on the current status of the network. In addition, we discuss recent important scientific results from analysed data, including: low-degree rotational splitting results covering the period 1981 to 1995; and the measurement of low-frequency modes, down to \sim 1.2\,mHz, in a power spectrum generated from 32 months of recent BiSON data.
