Hi,

 

I finally had some time this afternoon for a quick solar sketch. After opening my book I found that my last sketch was almost 2 years ago! Luckily, you all have been posting extremely good sketches to look at during that time :)

 

Today at around 16:00 UTC I observed the Sun through my 55mm refractor, knowing that a very small active region should be visible. Expecting a tiny dot, I started at 58x and moved upward in magnification, though I was unable to detect any sunspots. After about 10 minutes of searching, I decided to back away with the only other eyepiece on hand - a 25mm orthoscopic. Almost immediately, the tiniest point was readily visible. After some time, I switched back to 58x to check if it would be visible with prior knowledge of the exact location. It was visible as a small, extended spot, but only for a second or two at a time, spaced at 10-20 seconds on average. The seeing completely smeared out the sunspot most of the time. Below a 1mm exit pupil, eye floaters gave many false positive sightings as well. The only way I could be sure that I was viewing a sunspot and not a floater was by moving my eye to make floaters move relative to the Sun's disc. Today turned out to be a good lesson in atmospheric turbulence and patience.

 

Below is the almost barren view at 14x:
