Here are today’s solar images taken from Al Sadeem Observatory, March 31, 2021.
The sky was mostly clear with intermittent moderate breeze which provided good transparency but average seeing at the time these images were taken.Â
AR2812 has decayed completely into plage; leaving the Sun at its spotless and inactive state at this moment. The latest sunspot number (based on visual count and Wolf number calculation) is 0. SIDC and NOAA-SWPC reported a weak B7.0-class solar flare occurred yesterday, March 30, from former AR2811 which is approaching the NW limb.
Nothing significant going on with the Sun lately with just several short stable filaments at the Sun’s extreme southern quadrant, small enhanced plages associated with former AR2811 and AR2812, as well as few small quiescent prominences at the opposite NW and SW limbs, as distinctively captured in H-alpha imagery.
Space weather agencies* forecast solar activity to be at very low levels with chances of solar flares of up to B-class intensity only. Close monitoring is being conducted by numerous space weather agencies for any significant development.
Equipment used are Skywatcher 120mm refractor telescope with Baader filter and unmodified Canon EOS 1D Mark IV DSLR camera for visible imagery. For H-alpha imagery, the equipment used are Lunt 60mm H-alpha solar telescope, and QHYCCD 290III mono camera; all mounted on Skywatcher EQ6 pro mount Pre-processing of visible solar images was performed in PIPP, stacking in Autostakkert, slight wavelet adjustments in Registax 6, and post-processing in Adobe Photoshop CC.
