solar flare

[mjasonmathews]

I'm new to solar astronomy and have been using a Coronado PST and comparing it to images taken by professional telescopes (http://halpha.nso.edu/), and pleased to say I get to see all the detail that they seem to capture in photos. But earlier today Learmonth observatory captured a solar prominence 5 times larger than anything I've seen yet, around UT 2017-08-02 00:00:30 to 2017-08-02 00:50:30 lasted for about an hour. About 20 degrees CW of the emerging sunspot. I missed it unfortunately, but my question is if this size is normal and how often could I be expected to see them.

Welcome.!

That prominence was a wee baby prom compared to those seen during solar maximum.

Here are a couple pictures of prominences during the last maximum in 2012-2013. Stay with it. We are approaching minimum but we will be back at maximum in a few years and you will have learned the hobby during a time when you had to notice the most minute details, like I did.

Good catch! I wish I had gotten a photo of that one.

Hi:
Got this one in 2005 with a Starlight Xpress HX516 one shot camera.
It was a long and brilliant protuberance.
Regards,
Eric.

A very warm welcome! I think even now the Sun is quiet you can catch some amazing prominences. I have been watching all through solar maximum and I only picked up my first large prominence lift off a few weeks ago in this so called 'quiet state' the Sun never has a dull moment, it is just a matter of being lucky I think
