For the month of April our min. av. temp was 1.2C up at 9C while our av. max was up by 1.5C at 21.6C.

Our rainfall was also up by 55.5mm at 97mm while our year to date is still 42.25mm above average at 353.75mm.

Anyhow May is off to a damp start.

Cheers.

Here's something new- the BoM has issued a space weather warning.

The Bureau of Meteorology's Australian Space Weather Forecasting Centre has forecast a geomagnetic storm event of level G4 (severe) on the global G-scale.
...
Geomagnetic storms of G4 level can potentially disrupt:

critical infrastructure such as power grids, causing power outages
satellite services, affecting communications and global position, navigation and timing services that use high-frequency radio communication
The Bureau continues to monitor the situation and will provide updates of significant changes.

G5 is the highest warning level.

I'm curious about the photographic data. What aperture ratio does the lens need (standard or expensive high-speed lenses) and the exposure time (seconds?). I suspect you can't see northern lights at all with the naked eye at low latitudes. Correct?

Yes you won't see the aurora borealis (northern lights) here down under, but you can see the aurora australis (southern lights).

Sadly I missed the spectacle due to the heavy cloud and rain occurring at the same time.

Cheers.

D'oh!

I've had luck with cheap camera (less than 10gbp) nd an expensive one (no change from 2000gbp). Small appature (large f-mumber), long exposure (several seconds) is said to be best, but the auraura is realy intense then even a point amd click camera or phone will get reasonable results.

Well, Tassie is certainly getting the snot knocked out of it lately.
Gale force (and stronger) winds over the last few days, and tonight and tomorrow even stronger winds are expected & this time with flooding to top it off.
Power outages for some are likely to take up to a week to be resolved.
