The first entry is always the pin's source. Overall confidence is a weighted average of how firmly each reference supports the start and end times used above; a reference counts half as much for every 180 days older than the newest.
SKAO's own science-operations timeline puts SKA-Low's AA2 Science Verification at 2027, and the observatory has said verification is offered with AA2 in the first half of that year; with no day announced the pin takes the end of the stated window.

Something missing or wrong? Say it in your own words: a link that backs this pin up, a different start or end date and why, or a fact it lacks or gets wrong. The AI checks it against this pin's sources, searches for better ones, and adds any page that backs you up. The pin's own sources still count most.
