untilGRS Transit on Jupiter, crossing the meridian at 4.18am with Jupiter at just over 21 degrees altitude. GRS starts to come onto the disk at around 2.10am, disappearing at around 6.15am. A couple more events too, an Io Shadow Transit starting at 4.22am and an occultation or Ganymede at 4.29am. Full timings in the attachment. Best time to view is probably 5.18am with both shadow and GRS well positioned.

untilAs per Chris's post, GRS and a shadow transit of Io are visible tomorrow morning, weather permitting of course! Io Shadow Transit starts at 2:28am, finishing at 4:39am GRS Transits at 3:32am, and Jupiter itself transits the meridian at 4:53am Between 3:30 and 4am could be an optimum time, Jupiter at around 19 degrees and above, not far off its highest at 21 degrees.

Io shadow and GRS -

Latest try at Jupiter, with GRS and Io's shadow., It MAY be that a slightly bright patch to the right of the GRS is Io or I may be fooling myself... -
As per the heads up, GRS was transiting at 6.02am this morning, so with the promise of clear skies the alarm was set. I was too lazy to setup the AZGTi further down the garden, which would have been better, so I was stuck closer to the house and trees with the scope on the Giro-WR. Lovely views right from the start really, GRS heading for the meridian showing some nice colour although not as dramatic as I've seen it in the past. I could see the white separation between GRS and SEB, north and south polar regions and what I assume was the South Temperate belt and Zone. Hints of a festoon dropping into the Equatorial Band. This was another occasion when I tried cyclops first, then switched to the binoviewers to see if I preferred it. Binoviewing, on this occasion, definitely made the detail easier to access although that has not always been the case for me. I was at x230 ish and floaters were well controlled. I thought the seeing dropped off after a while, until I defocussed and realized I was observing through the twigs of one of our trees! Amazing that I could still see some detail even then. Loppers required before the next outing I think, plus putting the other pillar extension on! What a lovely way to start the day. Blackbird singing his heart out and the gulls floating gently overhead on their way to the reservoirs. The Parakeets had yet to start their noisy morning commute! Two last surprises. I thought Saturn might be visible, and did catch it just before it was occulted by......my house! OK views but good just to see it again. Finally, despite it being quite light at gone 6am, Arcturus was clear and I could also still see Izar so I popped the scope onto it. What a beautiful sight! Very well controlled faint diffraction ring around Izar and its secondary was as clear as I've seen it, lovely separation and nice almost greenish blue colour to my eye. It has always been bluish grey to me, so perhaps just a trick of the daylight. Great way to finish off, then back in for a warming cuppa and a little three year old who wanted a cuddle .

The GRS is perfectly positioned right now on Jupiter, pretty much dead centre a few minutes ago. The seeing seems pretty decent here in Bedfordshire at the moment as well!

First time imaging since April of last year! Managed to grab three 1000 frame videos between it being dark enough for me to see Jupiter and it going behind the row of 40 foot Sycamore, Oak and Beech trees that back onto our garden. Scope: Celestron C9.25; Mount: CGEM; Camera: QHY5LIIc; Lens: Explore Scientific x3 Telextender; Capture Software: EZPlanetary 3 x 1000 frame videos, centred and cropped in PIPP, stacked & RGB aligned in Autostakkert 2 with wavelets done in Registax 6; post processing and turning into a GIF. in PS CS4 Seeing was very poor with some very high thin cloud. I think my focus was also off and as I haven't used my scope in anger for well over a year the collimation is probably way off. But hey-ho, at least I've finally managed to enter something into one of these competitions instead of living vicariously through others efforts! ? -
Last year I didn't have a barlow yet, I kept taking photos of Jupiter with great quality mostly. This year I finally got my barlow and was severely disappointed with my first Jupiter shot. Blurry, dark, and bad. Then my 2nd shot was a bit better, then the 3rd better still. I've somehow managed to keep getting better shots this year, this being my 5th. This is now easily my best shot of Jupiter ever, or of anything really in terms of quality. I'm really quite pleased with it. 6 Inch Mak 1800mm Skywatcher + EQ5 Explore Scientific 2x Focal Extender (Barlow basically) ZWO ASI 120 MC 2 minutes of footage FireCapture + Astrostackert + Registax + GIMP + Lightroom 2017-04-09 - 0:46 local time Taken from Amsterdam, Netherlands

The picture was taken 13th april in Alicante (Spain). We are at sea level so seeing was mediocre (~7/10). Telescope: Celestron Nexstar 6se Camera: QHY5L-II Color Barlow 2x: Chinese unbranded Stack of 120sec video using pipp+autostakker and color adjustment capture NX. Warm regards from Spain! Vicente

Amazing coincidental transits of the Great Red Spot AND Ganymede on Jupiter shot using my Orion Deep Space Video Camera II and my Orion SkyView Pro 180mm Mak around midnight last night (April 22). Ganymede can be seen casting a shadow along the northern limb. The GRS can be seen roughly near the center of the planet. "Intrapsychic Conflict" is introduced as the musical landscape, not unconscious turmoil, lol! Enjoy! Reggie- 4 replies

Hi all. Sharing my capture of Jupiter from 19 April 2017. The video comprises frames from 1622UT to 1718UT and shows the GRS traversing the planet. Video can be viewed at either the youtube or attachment link below. https://youtu.be/8M7d3m34c5I 2017-04-19-1622_1-RGB_pipp_x264.mp4 Equipment used: Celestron C8, QHY5L-II-C, GSOx2.5barlow -
Finally having some lovely views of Jupiter this evening (morning!) Tak FC-100D with Leica zoom and x2.5 PowerMate, this is giving better views than my BGO's which is normally the case. Backing off the mag a little is helping the contrast, and the GRS is rotating nicely onto the disc. It's looking quite dark and red, with a nice separation from the belt. Plenty of other detail visible, including what I think is a dark barge fairly centrally positioned currently, plus the lighter belts in the polar regions. Must look up my Jupiter terminology! Frost on the scope, had to use a hairdryer to clear it just now. Warming up for a few minutes whilst GRS gets better positioned then will head out again. I've been doing some interesting comparisons between my TAL and the Tak which I will comment on elsewhere. It's rather a harsh comparison for the poor TAL, and I'm pleased to say the Tak does warrant its rather high price!

Hi all, Some days ago I released a new project at animating the cloudbelts of Jupiter and the GRS. In order to have an almost continuous monitoring of Jupiter, we contacted 91 amateurs from all around the world to ask for permission to use their images in this project. It took a full year and thousands of hours of work to get all the pieces in place but I'm quite pleased with the results. John Rogers, Director of the Jupiter section at the British Astronomical Association has written: "An amazing animated map of Jupiter's winds has been released by Peter Rosen and colleagues in Sweden, portraying real observations from images by amateur astronomers over 3 months in 2014-2015. The map (in various projections and perspectives) shows Jupiter's winds in glorious detail, and this is by far the best such movie ever produced from ground-based images -- worthy to compare with the Cassini movie." I hope you enjoy it It is now up and running at https://youtu.be/YZc1Y662jtk /*Peter Rosén

Hi all, just a heads up for the GRS and Io transit on Jupiter tonight. GRS on show now till Io starts to transit at around 22:58 GMT, then Io's shadow on view from 00:07 GMT in the morning. Just a little warm up for the Mercury transit tomorrow!

Hi everyone. I recently acquired a ZWO ASI120MC-S and so with the bright summer skies I've turned towards solar and planetary lately. I'm not great at either, but I'm learning This is the result of my efforts from last night and I'm quite pleased with how it turned out given it was ~3-4 hours of sitting in the relative cold of my front garden. I've never managed to time weather & my availability with the GRS or a Jovian moon transit before so that's two firsts for me. The seeing was "soupy" to put it lightly, especially towards the end when the planet got lower in the sky and ended up over the roof of a house across the road, but I can't complain - at least it was clear! I took a video around every 5 minutes for almost 2 hours, stacked the best frames, then compiled into an animation of 19 frames that loops back & forth. Io started off about 1/3 of the way across the face of the planet when I started recording data so it's a bit tough to see but you can follow it back across once it pops out the other side. Thanks for looking! I hope the attachment works correctly because I couldn't seem to get the gif size down below ~14mb, so I apologise to anyone on a slow connection!

Hiya, a glance at Jovemoons yesterday afternoon indicated that the GRS would be nicely positioned early enough in the evening for the kids to have a look. So, I set up the scope around 7pm, and we had a look. For me, seeing wasn't great, but the GRS did shimmer into view from time to time as the planet drifted down through the FOV. My eldest boy (10) had a look, and, though it took him a little while to get his eye in, he reported seeing it, but not very clearly – it definitely came and went. Around 8 my wife and youngest son (8) came home and had a look. My wife initially struggled to see the GRS, but eventually got there. My youngest, though, as soon as he put his eye to the EP exclaimed 'Wow! The Great Red Spot!' He said it was really clear and red ... Even at 240 times mag he said the GRS was clear, but a bit fuzzy, whilst to me the planet was better at x136 in the ES 8.8. Oh, for younger eyes ... Kev
