SOT shift report 2010-12-23 L4172 File created at 2010:357:13:22 UTC = 08:22AM Dec-23-2010 EST End 11:00:00AM EST; SOT Lead: Ed Kellogg PLAN: OBSID 12995, M83 2010:357:10:48, ACIS-S NONE - REMNANTS, BINARIES, AND DIFFUSE EMISSION IN THE NEARBY GRAND DESIGN SPIRAL GALAXY M83 MP: There was a medium term TOO request yesterday. Although it might impact the upcoming two week load, more likely it will go into the week of Jan. 10. S/C: all quiet. SIGNIFICANT SOLAR ACTIVITY: At midnight UTC the visible solar disk had 1 spotted region, just forming. Earth is exiting a solar wind stream. GOES X-ray flux: Flux is at the lowest background level, mid-A range. No obviously Earth directed CMEs were seen in LASCO or STEREO images in the past two days.

When the stratosphere is clear (not 'dirtied' by volcanic aerosols) the shadow and therefore the eclipsed Moon is relatively bright." A clear stratosphere "lets the sunshine in" to warm the Earth below. Yesterday's bright eclipse reinforces a conclusion Keen reported at the SORCE conference in 2008: "The lunar eclipse record indicates a clear stratosphere over the past decade, and ... this has contributed about 0.2 degrees to recent warming."
