(meteorobs) Off topic... impacts on Jupiter



Greetings all...

This was on the RASC list this morning...  Bit off-topic, comet-related, but
probably of interest to many meteor crew with scopes...

>I looked at Jupiter shortly after it rose last night (about 11:45 pm)

>immediately saw a very small black spot near Jupiter's meridian on 
>the S edge of the first faint band S of the large S equatorial band 
>(perhaps at about S latitude 20 degrees(?)).  10 minutes later it had 
>noticeably rotated with Jupiter away from the meridian.  I could see 
>it in all three of my telescopes (444 mm, 200 mm, and 100 mm, 
>although in the smallest telescope it was distinct but not obvious 
>due to its tiny size).

>According to the Observer's Handbook, no shadows of the Galilean

>(from 5:30 to 6:15 this morning, Friday, Aug. 7).

>David (Levy) said that if there was an unexpended fragment of SL9,

>Has anyone else seen the spot or have any other information on

>System II on Jupiter where Jupiter rotates 36.26 degrees/hour, the 
>spot should be near Jupiter's meridian at 1:30 am Saturday 
>morning (i.e. tonight).  I shall be looking!
