We have recently published the 300-MHz component of the GaLactic and Extragalactic All-sky MWA survey (GLEAM-300), with 338k sources covering the sky up to declination +40 deg, with ~120" angular resolution and ~9 mJy/beam noise. The description paper is published via PASA: doi.org/10.1017/pasa....

Some bougainvillea in the garden. After 13 years of use, I've finally replaced my trusty Canon 1000D - still using the same 60mm and 50mm lenses (for now), but the new camera is a very nice upgrade.

Close-up view of white bougainvillea with some small flowers poking through the bracts.

Magenta bougainvillea with small white flowers. More bougainvillea leaves and flowers are out of focus in the background.
