(with us was also 6 year old boy Matjaž)
16th of August 2001, at 20:40 UTC with CCD ST7 (no Filter), exposure:2X90s,
telescope SC 10", f/6.3", city Ljubljana, state Slovenia.
We estimate CCD magnitude near value 14.5.
See
Photometry Reference Images.
Picture is bad quality because image has been done from city Ljubljana,
where light pollution is very strong.
One detail: during taking down images we saw between Ursa Major and
Ursa Minor very (exceptionaly) bright flying (burning) object
(at 20:56 UTC, magnitude near -10, max. wide about 3 degrees,
without trace, the
event hav took about 3 seconds).
The object is
extinguished below Algol. We have never seen such thing yet.
