MalVeauX Posted February 26, 2021 Share Posted February 26, 2021 Heya, Woke up to fog, but was blessed with some good seeing and a clear sky this morning. I was able to get close to some limits with high resolution setup and after seeing deteriorated went to a moderate resolution setup for a wider field of view. I spent most of the time on AR2804 as it has evolved into a really interesting sunspot with a huge lovely penumbra with lots of fibrils and the plage around it has lots of great activity including minor flaring. Upper chromosphere and lower photosphere represented in 656nm and 600nm wavelengths to handle the seeing. Seeing was spiking to 0.8 arc-seconds this morning, so that's where I captured the 200mm data, and when seeing was closer to 1 & 1.2 arc-seconds I captured the 120mm data. I was able to piece together a short time lapse of AR2804 from the 200mm data to see how rapid the plasma was moving and represented real time of only about 4 minutes.
