From today (August 11th) up until Friday the yearly Perseids meteor shower will have its peak. This phenomenon is not only interesting for amateur astronomers, professional astronomers will be observing them as well.
STORIES
In Humans of ASTRON we share stories about the people at ASTRON. Who are the people behind the discoveries and innovations and also, who are the people that make sure that everything runs smoothly? In this second part of the series, we’ll be sharing the story of Jorrit Siebenga, who joined ASTRON in 2017 as research instrument maker.
Throughout the history of astronomy, women have played essential roles towards astronomical breakthroughs. In this article we highlight but a few of these women identified in history from 1600 to the modern era.
In Humans of ASTRON we share stories about the people at ASTRON. Who are the people behind the discoveries and innovations and also, who are the people that make sure that everything runs smoothly? In this second part of the series, we’ll be sharing the story of Emanuela Orrù, support scientist at ASTRON since 2012.

Enhancing the Value and Sustainability of LOFAR Science Archive

LDV is reaching the conclusion of its first phase of operations at Surf. The storage occupancy was reduced by 7.5 PB through resampling of beam formed data, compression of interferometric data and a large data placement action. This gain in storage translates in a saving of about 56 kEuro/yr. Curation of data enabled the removal of duplicates and the addition of quality flags. Currently, preparations are ongoing to perform a major retirement action (~9.5 PB distributed over the three LTA sites) of the early cycles (0-6) archived data with no legacy value.
The next operational aim at Surf is the generation of higher level data products by running the LOFAR Initial Calibration (LINC) pipeline on a significant portion of the archived data. For the first time, calibrated visibilities through the observatory processing framework with latest workflows will be offered to the astronomical community.
Furthermore efforts are ongoing to extend the processing framework infrastructure at the Juelich LTA site, for enabling the next round of data editing operations with an expected duration of 1 year. As a result more than 4 PB of tape storage space will be gained. Looking ahead, the LDV processing infrastructure will be expanded to support the LOFAR2.0 MPS operations, marking a key step toward future-ready science operations.
