There were five C flares and an M flare during the past 24 hours, all released by NOAA AR 12065. The long duration M1.3 flare peaked at 18:35 UT on May 24. No Earth-directed CMEs were observed. STEREO COR2 B imagery registered a CME at 23:09 UT on May 24, but this CME was probably associated to a backside event. In the next 48 hours, the probability for C flares is very high (95%) and for M flares around 60%, especially from NOAA AR 12065.Over the last 24 hours, the solar wind speed as observed by ACE decreased from around 450 km/s to about 430 km/s. Meanwhile the magnitude of the Interplanetary Magnetic Field (IMF) varied between 2 and 4 nT. Over the last 24 hours, geomagnetic conditions were quiet (K Dourbes between 1
and 3; NOAA Kp between 1 and 2). Quiet geomagnetic levels (K Dourbes < 4) are expected on May 25 and 27. Quiet geomagnetic conditions with active (K Dourbes = 4) periods are possible on May 26, due to the expected arrival of a coronal hole high speed stream.

From a camp on the northern shores of the Great Lake Erie, three short bright meteor streaks were captured in this composited night skyscape. Recorded over the early morning hours of May 24, the meteors are elusive Camelopardalids. Their trails point back to the meteor shower’s radiant near Polaris, in the large but faint constellation Camelopardalis the camel leopard, or in modern terms the Giraffe. While a few meteors did appear, the shower was not an active one as the Earth crossed through the predicted debris trail of periodic comet 209P/LINEAR. Of course, the long bright streak in the image did appear as predicted. Early on May 24, the International Space Station made a bright passage through northern skies.

If you are in dark skies and can see the Milky Way streaming up from the horizon, you may notice a black area with two little fuzz balls in it that look like puffs of steam. If you are in suburbs or cities, you may notice just a fuzzy star above the spout. The fuzzy star or fuzz balls are the Lagoon and Trifid nebulae, or Messier Objects 8 and 20. You are seeing two star-forming regions toward the heart of our galaxy.
The Trifid is a little dimmer than the Lagoon. Trifid got its name because in photographs it has three distinct lobes. The Lagoon got its moniker because it looks like a round pool just outside the ocean of the Milky Way.
