Aurora Borealis March 2004


A nice start in March with a couple of aurora bursts in the night 9/10. All the night there was some activity, but the two better and shortlived bursts took place at about 22UT and 23.30UT. Two more minor displays were witnessed on 9/10 Mar and on 18/19 Mar. Both were a bit surprising to me as there was no forecast of them (to be seen in my relatively southern latitude).
Night 9/10 darkened nicely allowing astrophotography OK. Then (about 19.45 UT) surprisingly a strange greenish light was pulsating in NW (about cycle/minute) and some faint light columns rose from below. (Two last images on row 6.) Later this aurora was faintly glowing low in north trying to raise faint columns at about 23-24UT.
Night 18/19 did show a very faint aurora glow all night and a minor burst at about 23.45-00.00 UT showing a low arch and a few columns of light (the rest of images). This activity was a bit harmful to astrophotography spoiling all images which extended to 40 degrees or lower in northern horizon.
