Project Status
The DASCH project has been a herculean effort spanning two decades. In order to ensure that the plate scanning is brought to completion, and that the resulting data are archived and as useful as possible, the project is undergoing an overhaul under the direction of the Harvard College Observatory. During this time, our servers will be down and access to DASCH data via existing interfaces will be limited. Please contact Purvang Patel, Executive Director at the Harvard College Observatory, if you have questions.
