The Sun Online and solar activity. Abril 1, 2014

The Sun produced just a handful of low C flares over the past 24 hours, the strongest occurred in NOAA AR 2026 peaking at C3.6 level at 14:15 UT, March 31 and another C3.3 flare originated from NOAA AR 2022, peaking at 00:50 UT, April 1.
Solar flaring activity is expected to remain at C level with only a small probability for M level flares.The solar wind speed is steady at around 400 km/s with the magnetic field just slightly higher than yesterday: between 4 nT and 7 nT.
Geomagnetic activity was unsettled in the second half of March 31 later returning to quiet despite the anticipated arrival of the March 28 CMEs. Local K Dourbes is presently rising from quiet to unsettled levels. The coronal hole that passed the central meridian on March 28 may become geoeffective and further unsettled conditions to minor storm levels are expected when/if the CMEs of March 28 and March 29 arrive.

Space Station Robot Forgets Key Again

Space station robot AFJ013 has forgotten her space lock key again. The frustrated robot was reduced to tapping on a space station window and asking for a human to let her back in — for the third time this week. “Yes, she did a great job adjusting the tolerances on the new science module, but why she can’t remember to take her key is beyond me,” said incredulous station commander Koichi Wakata (Japan). “We would keep the entry unlocked but we are afraid that space aliens will come in and raid our refrigerator”, the astronaut lamented. Happy April Fools’ Day from the folks at APOD. In reality, International Space Station astronaut Wakata poses in front of a Cupola window while the Latching End Effector, attached to Canadarm2, is visible just outside.

The Carina Nebula (also known as the Great Nebula in Carina, the Eta Carinae NebulaNGC 3372, as well as the Grand Nebula) is a large bright nebula that has within its boundaries several related open clusters of stars. Some papers generally refer to this as the Carina Nebula, mostly because of differentiating the many paper published on this object, but the historical precedence as determined by southern observers like James Dunlop and John Herschel, who have both termed it the Eta Argus Nebula or Eta Carinae Nebula. John Herschel also describes “The star η Argus, with the Great nebula about it.” with many of his subsequent published papers supporting this.
