Notes

The conditions were fairly good. The sky was reasonably cloud free though it was hazy, half-moon quite bright. Session ended around midnight after the last flare and a fleeting visit from a satellite that was spinning very fast. Attempts to find M51 (Whirlpool Galaxy) were made but to no avail. Celestron 114 - It's first Obs night. Appeared relatively easy to set up in the dark. Didn't align the equatorial mount, but finderscope was aligned. Precision adjustment very useful, fairly easy to use.

Lots of detail observed along the terminator.

Three observed in total, magnitudes -4, -6, and -0. Not quite as impressive as the -7 we saw but flares nonetheless.
