Earlier astronomy fans were treated to the sight of the International Space Station crossing at speed over the dusky Donegal sky.
The station – 250 miles above earth – could be seen streaming past Donegal just after 10pm.
Now an alert for the Aurora Borealis has been issued by several organisations for tonight – and tomorrow night.
Softservenews.com reckons August could see a series of displays.
With skies relatively clear of cloud overnight tonight, this could be the night to see this wondrous display.
The National Oceanic and Atmospheric Administration (NOAA) Space Weather Prediction Center has issued two magnetic storm watches (one 24 hour watch, and a second for 48 hours) indicating a Coronal Mass Ejection (CME) or a high speed solar wind stream emanating from the Sun may be heading towards Earth.
These fast moving charged particles can cause a Northern Lights display.
NOAA says that the beginning of a storm watch does not necessarily predict the arrival time of the aurora-causing particles, rather it indicates that, within the watch period, increased activity is expected.
