Sunspot AR2738, 16 April 2019

Here's a picture of the new sunspot I took today. Let's see how the weather will let me monitor it.

Photographed with a cellphone camera from an image projected by a Sunspotter Telescope. The image contrast was increased using FIJI.
 My hydrogen alpha telescope shows that the sun is otherwise not very active.
