search on the LSE site, I can't share a URL:
What are auctions?
During the trading day, the matching of buy and sell orders takes place on a real-time, continuous basis known as regular trading. Auctions differ from regular trading as matching is paused for a period of time, during which orders are collected from the market, which is known as the Call Period.
