Evolution of Solar Prominence,
19-22 April 2019
Four days of clear skies provided the opportunity to image the evolution of a large prominence on the solar limb. The prominence may be associated with a large sunspot, designated AR2738, which recently passed out of view on the solar limb.
I used a Lunt LS50THa B600PT Hα solar telescope and QHY5P-II colour camera. To create each image below, I recorded a 40 s video, then stacked/processed it in Registax 6 and cropped and adjusted the contrast in Photoshop.
Times are in UT.
