Google has invited us to an obscure corner of San Francisco tomorrow for a special announcement concerning Chrome. It all starts at 10:30 a.m. Pacific Time, and we'll be live-blogging the event from Dogpatch Studios.

What the announcement will be, exactly, we don't know yet. Chrome OS is Google's browser-based operating system that runs Web applications only. It's unlikely that Chrome will be ready for Netbooks this year as earlier promised, but the Chrome team might be demonstrating a near-final version for us. Or, it's possible Google is ready to take the wraps off its Web-based version of an app store, called the Chrome Web Store.

Be sure to come back here tomorrow morning, or sign up below for a reminder e-mail.
