  1. Date: 25/10/17 Time: 1600-1630 Scope: Lunt60+DS60 After what seems like an age, I finally got the chance to pop out and see the sun this afternoon! Must be at least 10 days as the first of the two (new to me) regions is approaching half way (6 day position) Seeing was poor, I had to fight through some thin clouds - Note that as long as you can see shadows being cast on the ground then you can tune an Ha scope into the sun and get a worthwhile image! Initial tuning was not easy as the disk was hidden in thin cloud but I managed to tease out the first (larger) active region - once you have something on the disk then its just a case of fiddling with the (1) scope pressure (2) double stack rotation and (3) finally the double stack tilt - if the image improves keep going otherwise reverse the other way. - in the end, I had teased out quite a lot of detail in the first region, several filaments and plenty of plage plus the spot of course. Several other stand-alone filaments were visible at 7 and 6 o'clock plus some smaller filaments in the centre. Managed to glimpse a nice exiting filament at 10 o'clock too! Initially, the highlight seemed like it was going to be the prominence formation at the 2 o'clock postion (which was extensive and contained multiple smaller tree proms) BUT then a solar flare started up in the 2nd newer region - it got quite bright and lasted a good 10 minutes so was probably a reasonably powerful event - which became the highlight of the session If you get chance in the next few days then make the effort for a look, the spots are small but the regions that contains them are reasonably active and there is plenty of other activity across the disk surface to make the effort. The prominence formation was on the coming-in side so maybe there is more to come around the corner? Alan
  2. Date: 28/9/17 10-30 -> 11-00 Equipment: Lunt LS60 double stack, Pan24 & Pan19 in MarkV bino with x1.7 gpc I haven't posted on this topic in quite a while! Probably due to the fact we have been under pretty much solid cloud and rain since early July (here in Penrith anyway) with only the occasional smash & grab session being allowed Anyway, this week I have now had two decent sessions (Tue & Thur) so I thought I would write something down. It is fair to say that the opportunity to see THREE regions all active and on the disk at the same time are few and far between. We have been treated to some super large spots over the summer but I think this current configuration is the best of the year IMHO so if you get a chance get outside and take a look... TUESDAY On tuesday, we had 3 and a half regions on the disk with the other half headed off the far side! The newest region was really putting on a show with several flares observed during my 30-40 minute session. One was a biggie, lighting up a whole strand of faculae while the other were smaller single point flares. It was so good that I had to grab the wife to come see the action. The central active region had a lovely "C" shape filament that was in the process of breaking up and over the time period there was a noticeable change in the clarity of the "C" due to the shifting of the filament itself. Many emerging flux's were seen in this central region. (they look like pairs of "bright eyes") I also remember that the sunspots were looking fine too, two double spots and a single. There were two areas of several small prominences but this is a "spot disk" at the moment. * I have begun to notice that we seem to get "spot disks", "filament disks" or "prom disks" with one or the other of these 3 in abundance and a distinct lack of the other two. Probably just my imagination or need to put the disks in pigeon holes! THURSDAY (today) The most noticeable change from Tuesday is that the central region has really expanded. It looks like it has grown from the centre outwards. The "C" shape filament is now a less distinct but much larger "S" shape filament and there is loads of flux activity coming from this region. Its double spot is now merged to a single. This region is becoming a real beauty. The newest region is much less active today with only a couple of emerging fluxes observed. It does have the nicest spots and the penumbra surrounding them is much larger than the spots in the centre. Maybe more spot growth to come. There seems a general lack of pores near any of the spots but I dont know what the impact of this is on the spots themselves?? There is a lovely thick filament on the disk and with the higher power 19mm (12mm equivalent due to x1.7 gpc being used) it revealed some lovely detail. I did not observe any flare activity so it seems the sun is quieter than on Tuesday but the middle region is definately worth the effort to get a look if you can. These multiple region views are quite rare. GENERAL The conditions are better today than on Tuesday when I had to quickly abandon the 19mm higher power and return to the 24mm for a nice sharp focused view! All the best, Alan
  3. After a hiatus of over a year, I finally managed to dust off my Quark. Here are my first baby steps. I managed to catch a bit of the activity from AR2644, it was a lot quieter 30 mins later (animations), and some stills of AR2645, AR2648. Still got some white light stuff to process. And now of course I need to learn the dark arts of Solar processing. This is much harder than lunar/planetary work! and seems to take loads more disk space. A question for the experts - advice on animations, how long for each video (time or frames) and interval between them? thanks in advance Neil
  4. after 12 days of not seeing it, i got a few shots through the clouds at last, there not the best but anythings better than nothing eh. taken with ED80 2XED barlow 450d, 32frames staxed with regi. thanks for looking clear skys charl. ps only 4 more days to Christmas yippee.
  5. this is my first sol post , sorry about the colour, taken with AR127L and sony alpha, 2 pane mosaic ,its not stitched very well had to do it by hand as ice would not play ball. ive still got a lot to learn about sol images, all tips will be welcome. thanks for looking charl..
  6. Ok, maybe not as dramatic as the title would suggest but still Santorini is a geo-active volcano system so I'm going to claim that one. So as some of you may know we have just returned from holidays in Crete and went to Santorini for the transit, the whole place was spectacular. Truly a worthy place for witnessing such a special event. We witnessed some great sights too while we were there, the rising of a near full blood red moon and the dramatic sunsets but that's for another thread possibly. We stayed in a hotel villa high on the rim of the caldera and had a perfect view eastward over the ocean, the weather leading up had been perfect and the morning before I had a succesful trial run in clear conditions and had everything worked out. Settings were honed, best location found etc... However, that evening some disturbing developments were afoot which left me feeling a bit uneasy. You guessed it, cloud. It was the type of cloud that only forms at the top of mountains and nowhere else, lenticular I think. So to my disgust this was the scen that I awoke to in the morning. Unbelieveable, there had not been a cloud in sight for are whole trip or the days after. Thankfully though as you may be able to see(I do have better pics of the effect) there was a thin strip of clear air between the horizon and the cloud which was situated right over my head, although at the time I wasn't sure how it was going to play out. So it was now a waiting game to see what would happen next. Then at precisely 6:02am local time a first glimmer of orange began to peek over the horizon, YES!!!! I was going to be able to see it. My first few shots however were way out... the change of seeing had dramatically changed the settings I had figured out a day before and this played havoc throughout the transit and my plans. But still I had some degree of success and I am thrilled to be able to of captured and share with you some of the photos I took. Santorini Transit by Jarrod Bennett, on Flickr I do have some white light pics as well which I'll post when I get around to checking all the SD cards. There was a good 30 min or so chunk of the transit that I missed due to the clouds as the Sun got higher but it reappered towards the end so I'll go through it all and see what I can come up with. It's also worth mentioning that the Polarie performed reasonably well on it's solar tracking rate too. All in all I'm ectstatic to have seen such a special event. Jarrod.
