Submitted on 2010-05-04The ESA micro-satellite PROBA2 was launched last November with two solar instruments onboard: SWAP, an EUV imager, and LYRA, a UV radiometer. SWAP and LYRA have an open data policy. We are happy to announce the beta data release of the science data products.
We also announce the open call for the PROBA2 Guest Investigator Program to promote & fund SWAP and LYRA data analysis by external scientists (submission deadline June 10!).
For the time being, we have online the following FITS files in YYYY/MM/DD directories:
