Adelaide has been showing a persistent beam for the last week or so, along with the usual dots from all over the east coast and irregular beams in the west. In the past day or two Darwin Airport started showing partial circles, and then came up with a couple of colourful fan-shapes today.
Soon after the Darwin fan shapes were some odd beams from Cairns and Bowen radars.
Below is a look at the Adelaide beam which has been pretty well consistent for at least a week:
Adelaide radar is still stuck on high beam; Canberra radar has been throwing up the odd beam of its own, and Willis Island had an almost full circular anomaly today. This is the first time Willis Island has been seen to produce any anomaly since we began monitoring the radar at the time of Cyclone Yasi, fourteen months ago. It was followed three hours later by another colourful fan shape from Darwin, as shown below.
This update has been slow in coming (it is now the end of May) but here are the rest of the anomalies that occurred during April.
First up on April 9 is a circle from Geraldton in the west. Meanwhile, Adelaide is still stuck on high beam.
Next up is this colourful circular flash from Broome the following day, April 10.
Then back to Geraldton two days later:
April 17 saw Canberra light up:
The next series come from Bowen in Queensland on April 22:
