Solar activity - July 8, 2018

Submitted by jimwcoleman

The day started out clear but high clouds quickly moved into the Pacific Northwest skies, so I couldn't do much. Here's a photo I got of some limb activity on the sun today. I have blacked out the brilliant surface to make it easier to see. I was going to photograph surface detail and add it to this image, but the clouds moved in too quickly.  All in all, a fun two hours of observing but I had to end it prematurely.

Come on summer ... where the heck are you? Oh, yeah. It's on the OTHER side of the country ...

Solar Composite (most of it!)

Submitted by thenakedastronomer

As you can see in the photo below, the sun is BORING right now ... absolutely nothing going on.

So I decided to spend a few hours and do a composite of the entire disk. This is a combination of 30 images ... processed with Autostakkert and Registax ... but ... wait ... I missed a piece of it!

Well, I guess this just means I have to try again. Darn. Twist my arm, why don't you... ;)

Anyway, enjoy. This is what keeps you warm. Keeps you alive.

Coronal Hole

Submitted by jimwcoleman

There currently is a coronal hole on the face of the sun.  This is a cooler, less dense area on the Sun's surface and it's easy to see as it's pointed at the Earth right now. We are near the solar minimum so there's not much to see on the surface of the sun right now, but I did get this image today, using a Coronado SolarMax 90 and a ZWO cam ... 

Beyond the terminus...

Wow, after months of soggy weather or just plain snow, I finally got the new Atlas EQ-G mount out at 2 a.m. this morning. Didn't do much as I'm still not very familiar with the mount, having crossed over from Celestron mounts, but I did get a rough polar alignment and snapped a single shot of the moon, using an Astrotech AT72ED refractor and a Canon 60D. The interesting part of this photo is what you can see over the dark side of the terminator ... caught it at just the right moment to illuminate some taller peaks and crater walls.
