Covered California is exceeding some of its projections.

The health exchange says 828,000 Californians have picked new plans under Obamacare, which is 128,000 over earlier estimates.

There are six weeks to go in the current enrollment period.

Officials say more than 600,000 people are eligible for subsidies and that some 80 percent of enrollees have already paid their first month's premium.

Anthem Blue Cross of California, Blue Shield of California, Kaiser Permanente and Health Net lead the way among plans chosen.

The health exchange has had some problems enrolling Latinos, though, and it's launching a new outreach campaign.

Only 20 percent of people who signed up for Covered California identified as Latino in December and although that rose to 28 percent in January, the numbers aren't what was hoped.

Executive Director Peter Lee says they're now doubling Spanish-language advertising, improving the website and hitting the streets.

"We now have an extensive ground game in place, with more than 4,000 Spanish-speaking enrollment counselors and licensed agents in addition to thousands more Spanish-speaking county eligibility workers," Lee said. 

Latinos are a key group for the exchange: on average younger and healthier than the general population. Premiums paid will help cover the costs of older, sicker Californians.
