The cases of COVID-19 have continued to grow in the Coquimbo region, in particular in La Serena, Coquimbo and Vicuña. After careful consideration of the pandemic situation in the Coquimbo region and to safeguard the health of the observatory staff, the April 2021 GeMS/GSAOI run has been cancelled. We hope that observations later in the semester will be possible.
The GSAOI web pages have been updated to reflect the recent changes introduced by the replacement of the guiding unit in Canopus. The new guiding unit called Natural Guide Star Next Generation Sensor (NGSNGS or NGS2) has been installed in July 2019. The on-sky characterization of NGS2 have been taken in place in October and December 2019. Results from commissioning show an improvement in sensitivity of about ~2.5 magnitudes, compared to the previous NGS guiding unit. In addition, there is a large improvement in acquisition and offsetting.
