As promised a few weeks ago, here is the full light curve of the eruptive Be-star Gaia19eyy that has now been added to the data base since it re-opened. All the data ingested previously has been published in our sixth paper of the series “A survey for variable young stars with small telescopes: VI – Analysis of the outbursting Be stars NSW284, Gaia19eyy, and VES263” – see our publication page for a link to the paper.

We can see that we covered almost the entire outburst in the last year in four filters. There are a few outlying data points, which are mostly caused by data taken during non-ideal weather. The larger gap in the data is due to the object being too low in the sky to observe. If one looks in detail at the light curve there are some small systematic ‘jumps’ of a few percent in the data on some days. These are caused by flatfield gradients in combination with a German Equatorial mount. These systematic effects get removed in our off-line colour correction calibration if needed before we use the data in any publication.

Given the typical ‘period’ of the object of about one year, keep an eye on it, as the next burst should start at some point early in 2024!
