Episodes over the last 30 days An episode is one unbroken stretch during which an alert was running somewhere within this territory. Alerts in different rayons merge into a single episode when they overlap in time; most episodes are made up of several announcements. How many times — how many such stretches the period contained. Median — the midpoint of the duration series: half the episodes are shorter than it, half are longer. Average — the sum of the durations divided by their count. A few long episodes pull it above the median. Shortest and longest — the ends of the same series. The longest one is an unbroken chain of alerts, not a single siren. Days observed — on how many days of the period the source reported anything at all. Time the source was silent does not count toward the duration: an episode breaks off at the start of the silence and starts over after it.

The parts of this territory, from the loudest. Time is counted the same way — an alert anywhere within each of them.
When exactly?
A row is one day, a cell is one hour. The darker the cell, the larger the share of the hour the alert ran. That is how you can see that alerts cluster at night — no total reveals that.

At what hour most often?
When alerts begin — for the chosen period. An alert that started in the evening and ran until morning is counted once, at the hour it began.
By hour of day
Most often at 17:00.
By day of week
Most often — Tue.
Does an alert usually happen at this hour?
A different question from the chart above: not when alerts began, but what share of days an alert ran during this hour at all — regardless of when it started.
Calculated over a fixed 56 days, not the period chosen above: over a shorter stretch, a single day would swing the share. It describes the past and is not a forecast — do not use it as grounds to ignore a signal.
Peak at 03:00 — the alert touched this hour on 44.6% of days.
