Between clouds , managed this stirring sight. Very pleased to read that AR had appeared , this being AR 2738 which had disappeared around the limb for two weeks. In white light photosphere view there was plenty surface action and a couple of small pores. Plages usually show up here , but it was difficult viewing being near the limb. In Ha there was plenty action with arching prominences, plasma condensing and surface granulation.
A very fine show for our current solar minimum . 35 mm of aperture and wide field does give grand views,
Took this with my phone a few days ago.
Out of interest , I looked up the size comparison between Earth,proms and the recent AR 2738.Nick.
The most promising of forecasts soon breaks down into chasing gaps between the clouds. It seems best to get set up early !
Really surprised at how much detail the Hershel wedge gives. AR 2738 still in one piece , the smaller spots are more obvious . Some proms and filaments in Ha.
Looks like we’ll have to follow this on Gong , http://halpha.nso.edu/ always worth looking at before setting out , Nick.
Progressing across the disc , AR 2738 gave a lot of features . Almost annular with a small breach. Plenty features in white light. Really great observing ! Nick.
plenty surface action, the small spots have become more obvious, Nick.
Very surprised to getting even more solar action. A huge arc of plasma floated free way above the limb, this together with proms gave plenty to observe. The whole disc showed surface activity.
Using a green and polarising filter with the Herschel wedge at x65, the spot gave a really spiked edge. This came and went with the seeing , but settled, never noticed these spikes before. Again , a lovely day to set up and return , under clear skies ! Nick.
What a wonderful day to set up and watch the developments,
Here’s hoping for more ! Nick.
Not the best of seeing , light cloud didn’t help. But a welcome huge sunspot. Resolved by eye , it gave four near joined black areas with a large penumbra. Plenty of surface detail.
Got this using a Lunt Herschel wedge and a polarising filter in a Vixen 90mm. By eye there was also a smaller spot nearer the limb. Ha gave a huge hedgerow prom. This is a B solar flare event , those to the north will be happy to get auroras.
clear skies ! Nick.
21/2/19 Swadlincote C6r on Neq6 mount.
A short session before the Moon glow got going. This time it was the “snow Moon”, big bright and silvery as SWMBO pointed out .
Very surprised to get a lovely unfiltered view of NGC 2440, a bright +9.3 planetary Nebula in Puppis. Discovered by Herschel , it bears the hottest central white dwarf. Continuing with obscure a lucky view pulled out by averted vision of 15 Hydrae . The B companion giving a 1.2″ split with two further faint companions. Staying in Hydra and a great view of M48.
Two further challenges in Gemini , Σ1037 and Σ1081. Looking at the Trapezium , the E star was quite obvious , but no sign of the F . Probably as Orion rested on the town lights. We’ve got led streetlights, the glow is pretty fierce , but doesn’t give that horrible orange glow. Just a few clusters worth observing ,M46, M47 , M50 and the compact NGC 2420.
From here a six inch aperture (f8)gives equivalent views to my 8″ Newtonian (f6) , but with increased contrast and more defined diffraction discs on bright stars and planetary views. The seeing and transparency of the atmosphere dominate , but it is possible to get down to below one arc second separation. It’s quite surprising to get so much detail from simple equipment . The Eq6 holds the 11.5kg ota weight of the six inch refractor, with a carrying capacity of 25kgs , there’s room for more !
Lovely early session under ,
Clear skies ! Nick.
