Today's Great Prominences, and AR12704 | Quark | April 16th 2018

Post by MalVeauX » Mon Apr 16, 2018 3:44 pm

Heya,

Really chilly this morning here in Florida, weird! In the 50's F, but sunny and clear skies, so I couldn't resist taking a look at the major prom developments and decaying arch prominences from the past few days. AR12704 is more active and has more interesting features and has appeared in white light (but barely visible). In HA, AR12704 has plenty of interesting activity around it though. I imaged both wavelengths to show the comparison. Seeing was poor, a solid 1 most of the time. It was difficult to even focus in white light, so I wasn't able to get critical focus for the white light sunspot and dumped most of that data. I only kept one sequence of the white light sunspot to show as a comparison to it's HA brother. That sunspot is just so tiny in white light. But it seems more active than it was a few days ago, so maybe there will be something to look forward to over the next 2~3 days while it's still facing us.

Barely visible AR12704 in white light, compared to above's HA, so tiny.

Great set of images Marty. You're getting a good run of solar imaging in lately. I managed a very quick visual with the Lunt50 after work, but the clouds came too quickly for me to get an image in.
