It's hard to believe that it's been over a year since I posted anything astronomy-related.

I'm not yet ready for full nights up in the obsy, but unexpectedly I was allowed out to play during the day.

Here are a couple of sunspot pics and a stitched image from a session a couple of weeks ago. Not my best work, but it was fun trying to remember which wires connect what to what, and which software settings are best for the conditions and the data.

Yesterday saw an improvement in the weather. I managed to get out for an hour to nab this sunspot group:

The old spots have moved around a bit, there's not much new stuff following on behind.

No close-ups this time  🙁

In contrast to today, yesterday morning was clear, warm and calm. The Sun was putting on a fine display of spots:

Better late than never...

Plenty of significant active regions on display.

Things have moved on (around) a bit since then but they're still worth a photo just before sunset.

There'll be no pics taken here today - we're under typical Bank Holiday Weekend rainclouds  🙁

Observing Report 23rd April 2013 (Another huge sunspot group)

AR1726 is another biggie - more than 150,000 km from end to end.

It's "going around the corner" due to the Sun's rotation, so current views of it are foreshortened.

It makes an interesting target just before sunset, if you do pop out for a peek at it please mind yer eyes!
