We are now taking routine all-sky images with KAIRA, 24 hours a day. These are great as not only are we building up a fantastic data archive, but we are starting to get a good feel for some of the features.
In this image, there is a strong source on the south-eastern horizon. It is so bright that it saturates out all the other sources in the sky.
No doubt this is some RFI (Radio-Frequency Interference). It is possible to recover the data, but these require a reasonable amount of work. In the case of fast-burst RFI, sometimes it is easiest just to flag it (i.e. note it, but otherwise ignore it) and move on.
