Stella-Luna Observatory ✨🌙

Even with a fairly early morning start, the day's heat set in, roiling the air and overheating both astronomer and computer! The astronomer sweated. The computer became glitchy. Results were good, however, and today we're comparing views in color vs. monochrome, and white light vs. hydrogen-alpha. Earth's star was very photogenic today! Tracking sunspots? They are, top to bottom, at active regions 4479, 4478, and 4480. Clouds expected this July Fourth weekend. #sun #sunspots #astronomy

A surprisingly clear morning greeted us July 4, allowing farewell imaging of the big sunspots at active regions 4479, 4478, and 4480. All three were sources of flares and accompanying coronal mass ejections. All three are about to rotate over the western Solar horizon. Earthlings with clear nighttime skies last night (and possibly tonight) rewarded with auroral displays. These images all via our Askar 103APO telescope and Baader Planetarium Herschel wedge.
