Observing cosmic rays angular distribution is essential to study Forbush decreases, and doing it in real time is quite helpful for space weather forecasting. By analyzing this distribution one can detect anomalies and predict possible commencement of a storm. The ring of stations method described by Abunina et al. (2020) suits really well for this task since it does not require any complicated modelling.

We present an online tool built for this task. It collects hourly data from NMDB automatically and presents it visually as a longitude-time distribution plot. Apart from the plot itself, it also features the precursor index, which is intended to display likelihood of storm in the upcoming hours.
