There was a dim but rare this time of year display of aurora borealis [ Northern Lights in English, revontulet in Finnish ( Fox {tail emitted} Lights ) ] on July 15'th 2000 at my summer cottage. The G5 rated storm was seen in Asia, Europe and America down to latitude of 40 degrees. The coronae was centred here on Vega near zenith. The show started with very faint red in east at 22:10 UT stretched and finished with a colourful corona at 22:25 UT - reaching west horizon. The display was faint due to full moon and sun just 6 degrees below horizon. I got a very few exposures with a digital snap shot camera - of which all are linked to from this page.
