We have not had a look at one of our “old friends” NSW284 for quite a while. The last time we looked at it was in week 257, about 1.5yr ago. This object was the first Be type outburst star we accidently found in the data. We wrote a paper about this and two others a while back.
We found that this source shows outbursts roughly every 300 to 400 days. Thus, the live database, which has now data for over 2yr, should show two such bursts. And indeed, in the above image there are two bursts visible. They are separated by about 400 days, so everything is going as normal for the object. In the past, as can also be seen from the Gaia data, the object ad bursts of varying amplitude. Often at most two consecutive large amplitudes bursts where followed by a low amplitude or ‘missing’ burst.
With the object getting into prime visibility over the next few months, keep an eye on it so we can see what the next burst does, or if it indeed is weak or missing. It should start in about 3 months or so, but who knows ….
