Weekly Solar Image 6-16-12

Starting yesterday afternoon into today there has been a geomagnetic storm caused by large sunspot 1504. The aurora reached storm level as this sunspot crossed the face of the sun, and blasted 2 CME’s towards Earth.

Sunspots: 1504, 1505, 1507, 1508. 6-16-12

Sunspots: 1504, 1505, 1507, 1508. 6-16-12

This image of the sun is 100 images stacked in Registax with some post processing done in Photoshop. Images were taken yesterday (June 16, 2012) afternoon, but I ran into some issues when stacking.

Venus Transit With The APO

The Venus Transit event put on by the wonderful people of the Adirondack Public Observatory went off with a bang! It really turned out to be a great day, and there were so many people that showed up for the event. I’d like to thank the people of the APO for putting on the event, and all the people that showed up to the event. You helped make it a fun and enjoyable time.
The skies weren’t exactly clear, even up to 5pm – an hour before the transit started. But we setup on the beach anyway, and at the Wild Center. We were prepared for it to clear, and we were prepared with indoor events in case the clouds didn’t clear. Luckily we were blessed with clear skies from a few minutes before the transit started, right up until the sun set. After sunset the clouds slowly rolled in, and I drove through three heavy downpours on the way from Tupper Lake back to Plattsburgh.
For all images, click to enlarge.
As we were setting up on Little Wolf Beach people started coming in, much quicker than I had expected. There was quite the turnout on the beach, with many people interested in the event asking questions. Unfortunately by the time I got to Saranac Lake I wanted to get a picture on the side of the road, but then realized my point and shoot camera battery was still on the charger at home. Good thing I had my cell phone to grab a few pictures of people at the event.
At times I had quite a line building up around my telescope, people of all ages from children to seniors all seemed to be impressed with what they were seeing. Lots of “ooohs” and “aaaahs” from everyone. I’m just happy that I was a part of it. This was my first time involved in an event like this, and I have to say I loved every second of it. I also got my first look through a Personal Solar Telescope which was very cool to see some solar prominence as Venus was trekking along the face of the sun. There was also a table top dobsonian, a 10″ dobsonian, and an 8″ dobsonian telescope on the beach.
I don’t know what I did in order to miscount how many images I took for each stack, but I ended up with way more than 30 images per stack like I had planned. Glad I got more images than I had planned, it really helped sharpen up the images when stacking and editing them to really bring out Venus, and the sunspots that were visible.
The first image is comprised of 53 images, the second is 61, and the third is also 61. All pictures were taken at ISO200, and a shutter speed of 1/4000 prime focus with a white light filter. As the sun got closer to the horizon you can see that even through the white light filter the sun became a pretty orange color. Images stacked in Registax, and cropped in Gimp.
Here is a time lapse of the sun setting behind some mountains with Venus still in transit. Short 7 second video, best viewed full screen in HD.

Transit of Venus

I had previously wrote about the events of the Venus Transit in Tupper Lake at the Adirondack Almanack. I really wanted a post about it here on my blog too, as not everyone that follows this blog also follows the Almanack.

The Transit of Venus is quickly approaching, and the window of clear weather is very slim; but that shouldn’t stop you from joining the events in Tupper Lake held by the good folks at the Adirondack Public Observatory. This is the last time Venus will cross the face of the sun – from our vantage point of Earth – until 2117, which most likely no one reading this will make it to. If you do I would like to drink from the same fountain you are drinking from!
WPTZ News Channel 5 meteorologist Gib Brown has been keeping a close eye on the weather for Tuesday, but it’s still too early to make a final decision on whether it will be an outdoor event, or an indoor event. Final decision will be made by 7:00pm on June 4th. I have also been keeping a close eye on the weather, though I’m no meteorologist, I’m still at us having a 50% chance of having clear enough skies.
If outdoors the telescopes will be setup, mine included, at Little Wolf Beach in Tupper Lake, and there will be quite a few telescopes set up with solar filters to watch Venus as it crosses the face of the sun. There will even be a couple of Personal Solar Telescopes, which are built specifically for solar viewing. These telescopes give amazing views of features on the sun you can’t see with the white light filter like I have. The APO is also going to provide Eclipse Glasses for viewing the sun with your unaided eye safely.
If we are clouded out the event will take place at The Wild Center where there are plenty of activities planned, some of which for the younger people. Also a live stream of the transit via NASA. There will also be materials supplied by the Solar Dynamic Laboratory at the Goddard Space Center. Some of the materials include posters and cards with various images of the Sun with sunspots, prominences, flares, etc. There are also DVDs about the Solar System narrated by Whoopi Goldberg that may be given out as prizes for some of the games planned. We may even have a chance to use the STARLAB planetarium at the Wild Center. Indoor plans are still in the works.
If I receive anymore information about the event before June 5th I will be sure to post an update providing you with the information. I’m really hoping we have clear enough skies for viewing the transit because there is nothing like viewing it through a telescope with your own eyes.

Sun Filter and Sunspots

Last week I received my solar film, which is just the filter with no filter cell to hold it to the telescope. This is where a little bit of creativity comes in with making something that will hold the filter to the scope. The film comes with instructions, but I was lacking the correct cardboard material to make it the way they describe. Since I’m on a tight budget I made use of the cardboard boxes that the telescope came in, and made a nice solar filter cell. Hows that for recycling?!
I’ve been out with the telescope a few times to give this filter a shot. It goes on tight and stays on pretty good. Am looking for a way for extra security in holding it on. Although it fits tight, I want it to fit even better.

Here is my first stack of the sun, using 7 images stacked in Registax and edited in Gimp. I am still working on perfecting my focus while trying to image the sun. I got a lot of images, but only a very small handful (read: very small handful) that are in a decent enough focus.
