The Sun 11-4-09 – Good visibility = great proms!

Looks like my request in the last post was answered! This morning the atmosphere was indeed scrubbed up to around 11.30am with great transparency and above average seeing. These conditions allow the PST to “see” much more detail than normal and the proms generally look more detailed with finer strands of plasma. You can also shoot much faster in great weather with the exposures at max speed on the DMK21 and DMK41. A great day for it too with extended prom groups in SW, NW and NE. The proms in the NW and NE were very faint while the SW proms appeared bright visually. No surface action at all and none predicted by the satellites on the far side of the sun either so it looks like a dry period is ahead in terms of active regions. All images taken with the DMK41 and PST this time. South is to the right and west is up.
