Adds background
SAO PAULO, Dec 30 (Reuters) - Brazil's central bank sold $1.815 billion in a fresh spot auction on Monday afternoon, it said in a statement.
The auction was called right after the Brazilian hit the 6.24 per U.S. dollar, weakening 0.7%.
The central bank has sold this month nearly 22 billion in several spot auctions, in addition to further $11 billion in repurchase deals, as the currency hit historic lows amid worries with local fiscal situation and FX outflows.
The real was strengthening by some 0.3% after the auction.
