To whom it may interest.
Hi,
if some body is interested in an “older” observation of short timed
black-dark spot, I´ll annex a Word for Windows 6.0 –file with J.H.
Schroeter´s manuscript of "Beobachtungen verschiedener schwarzdunkler
kleiner Flecken des Jupiters, welche von sehr kurzer Dauer und im
Verhältnis mit der von Cassini bestimmten Umdrehungszeit des Jupiters
von einer merklich geschwindern Bewegung erschienen" (Observations of
different small black-dark spots on Jupiter, which are very short timed
and which appearing notable faster in relation to Jupiter´s revolution
determined by Cassini).
If you are not interested just delete it.
Thanks
