The Sun is basically featureless except for a few loose filaments, the fading AR12622 on the W limb and a patch og plages near the E limb.
Observation iss hindered by the relatively cool wind that make the temperature control of the filter-oven very difficult and cannot reach 59.0C, rendering most images off-band.
Despite these, small scale eruption of AR12622 was recorded.


Telescope: AP Starfire EDT 155 mm f/9.

stopped to 50 mm for disc images, with 4X telecentric lens (f/36) for closeups
filter: Solar Spectrum SO1.5/0.3A with CERF prefilter
Camera: Imperx 4M15
North is up, and east to the left.
