AR2835, High Res WL & CaK | HA | June 27th 2021


Recommended Posts



It's been a nasty few weeks here in Florida, the storming just hasn't let up until this afternoon in a solid 16 days straight of clouds and rain. I missed that last spot and missed out on some really great proms the past few days. Thankfully there's a new active region with a very interesting spot! AR2835 is pretty interesting because it doesn't have massive activity going on despite how it "looks" to us, and it's because it's magnetic polarity is very split and far apart, so there's no reconnections occurring resulting in flares (at least so far!). Lots of neat stuff going on in the inner spot with light bridges forming. These spots sprang into life over just around 2 days or so and are still going, so it will be nice to see them stick around for a disc face transit hopefully! I'll probably get rained out the next few days just because!






























Seeing Conditions:


Not my typical, I had nothing for weeks. This evening was my first chance to even look at the sky nice the beginning of the month. So after 4pm Eastern Time, I had not expected good seeing, but it was good enough to attempt things with good transparency between large cumulus clouds dragging nice air flow patterns behind them. Lucky imaging prevailed despite my averages to allow high resolution in 0.8 arc-second peaks for the continuum and CaK imaging.
