NELIOTA Archive

The NELIOTA Archive is automatically updated with new suspected and validated flashes within 24 hours of the actual observations (see observing schedule here). Scientists may obtain full access to the NELIOTA Archive by registering here. If you are already registered, please login by clicking here.

The table below lists the UT date and time of the start of the validated events (i.e. detected by both cameras), their duration, peak R and I magnitude, as well as their lunar coordinates, altitute, azimuth and airmass. Registered users can also view the suspected events, i.e. events which cannot be validated.

Registered users have access to the FITS data cube files for each event, which are provided separately for the R and I filter. These include:

  • the reduced (bias-subtracted and flatfielded) images
  • the background image (running average of previous reduced images) 
  • the difference images (between the reduced image and the background)

The reduced image files include 7 frames before and 7 frames after the frames that contain the event. The difference image files include the frames that contain the event and 7 subsequent frames.

If you plan to scientifically exploit data from the NELIOTA Archive, please inform us in advance and include the following acknowledgement in your publications:

This work has made use of data from the European Space Agency (ESA) NELIOTA project, obtained with the 1.2-m Kryoneri telescope.
