Solar cycle 25 begins with two small active regions, AR2753 and AR2754.

Solar cycle 25 begins with two small active regions, AR2753 and AR2754. Stack of Bridge camera images through a Baader solar filter reveals both of them barely visible, but they are just pores. However, they are at high latitudes and with reversed polarity relative to Cycle 24 sunspots. Images precisely cropped in Nicola's AstroCrop before stacking. The seeing was ver poor.

With terrible seeing: Stack of images of, new Cycle 25 active region. Imaged with an SVBONY SV305 and AstroDMx Capture for Linux running on a laptop with the Chinese Linux OS, Deepin; using the newly implemented Mono 8 camera mode. The scope was a Skymax 127 Maksutov fitted with a visual, Baader solar filter.
