Update of LYRA level2

The calibration of LYRA data (level 2) has been updated on December 31 2016 00:00:00 to take into account new information about the evolution of dark current, as well as the result of the last calibration campaigns. This update currently results in a small amplitude jump in the timeseries. This jump should disappear the next time the data will be reprocessed, in a few months.

 

Mercury Transit 2019

Mercury as it approaches the solar disk

All SWAP Images Available from the Mercury Transit on November 11 2019.

In preparation for the 2019 Mercury transit, the PROBA2 team have made a high cadence image campaign throughout the day. A movie made with all the SWAP data is shown below. All of our SWAP data products for this Mercury transit are now available here.

 

Ninth Call for PROBA2 Guest Investigator Program

The PROBA2 PI-team welcomes research proposals for the ninth round of its Guest Investigator program for research based on SWAP and LYRA data analysis by scientists outside the SWAP and LYRA PI-teams. We encourage in particular early-career post-docs and PhD students to apply, although more senior guest investigators' proposals are also welcome.

PROBA2 sees a Partial Eclipse on July 2, 2019

On July 2, 2019 the so-called Great South American Eclipse took place. The total eclipse path ran over parts of Chile and Argentina, where the Moon was seen to move in front of the Sun and blocked the sunlight out completely.

Evolution of a Coronal Cavity using SWAP, AIA, EUVI and LASCO data

The image on the right shows a coronal cavity observed by PROBA2/SWAP along with its associated filament as seen in SDO/AIA data. Coronal cavities are believed to be the low-density cross sections of magnetic flux ropes.

Synoptic Images of the Sun

Synoptic Image of the SunA synoptic map (or a latitude-time map) of the Sun shows the evolution of the Sun over a given period of time in a single image. The PROBA2 team have created a synoptic map of the Sun for whole Carrington Rotations.

PROBA2 Science Working Team Meeting 17

The PROBA2 team is pleased to announce the 17th PROBA2 Science Working Team (SWT) meeting, which will be held on Tuesday November 13, 2018 at the Royal Observatory of Belgium, between 15:30 - 17:30 local time (i.e. CET) in the Nadir room.

Solar Polar Images of the Sun

The solar poles are relatively unexplored regions of the solar atmosphere, this is due to a lack of satellites that have travelled over and through them. In this article we briefly explore how we can use current instrumentation to generate artificial polar images, and what might be learnt from studying the solar poles.

PROBA2 Partial Eclipse Observations - 13-Jul-2018 and 11-Aug-2018

Two partial solar eclipses were visible this summer: one on 2018 July 13 and another on 2018 August 11.

The majority of the eclipse in July took place over the Pacific and Indian Oceans, and a very small fraction above the southern Australia.

PROBA2 Science Working Team Meeting 16

The PROBA2 team is pleased to announce the 16th PROBA2 Science Working Team (SWT) meeting, which will be held on Monday August 6, 2018 at Royal Observatory of Belgium, between 15:30 - 17:30 local time (i.e. CET+1). 
 
As with most of our SWT meetings, we will present the usual mission status presentations and then we will have guest speakers present interesting science based on LYRA and SWAP measurements.
