Comment on Jupiter — November 6 in very good seeing by Mark

Hi wayne im a huge fan of your planetary imaging. You inspired me to buy a C14 and give planetary imaging a go. I have not had much luck yet tho. My images seem to come out blury and not much detail. What focuser do you use on your C14? What do you use to cool down your mirror?

An images from Glenn Orton using the IRTF is posted on the Cosmic Diary blog of Franck Marchis. No scar visible in the near infrared: No Detection of a Scar on Jupiter in the NIR

Does Curiosity have the capability to listen for Martian impacts?

Thank you very much for the update! It is wonderful that these days more and more observing programs seem to be building in some flexibility to respond to unexpected but interesting emergent events.

I just learned that Glenn Orton (CalTech/JPL/NHRA/Etc.) has obtained time on NASA’s Infra-Red Telescope Facility (IRTF) to study Jupiter for signs of an impact from yesterday’s fireball. This 4.2m infra-red telescope should be able to peer deep into Jupiter’s cloud deck for any of the tell-tale signs of an impact.

I haven’t heard of any of the professional scopes trying to see if there’s anything there. Since none of the amateur images have shown any signs of an impact, it’s unlikely that anyone will propose breaking into the schedule of the HST.

It’s not likely that a small impactor would leave a mark in the equatorial zone, due to the high cloud tops and convective flow in that region. Most likely it mostly burned up and the remnants consumed, just as happened in 2010 when Chris Go and Bird Wesley imaged a similar fireball.

Do you know if any large aperture scopes have looked for a ‘scare’? Is HST working in any observations this week? Have you heard any rumors of anything faintly visible?
