No sunspot monitoring was issued yesterday, March 26, 2020, due to unfavorable weather condition (mostly cloudy sky).
Here are today’s solar images taken from Al Sadeem Observatory, March 27, 2020.
The sky was generally clear with intermittent light winds which provided good transparency and seeing at the time these images were taken.
The Sun remains in its spotless and generally inactive state over the past 24 hours, extending its streak to 17 consecutive days. No major flaring activity was recorded. The latest sunspot number (based on visual count and Wolf number calculation) is 0. Despite the absence of the sunspot groups, the Sun exhibited few huge eruptive prominences at the (northeastern, southeastern, southwestern) limbs as the only noteworthy visible solar features as distinctively captured in H-alpha imagery.
Space weather agencies* forecast solar activity to remain at very low levels with chances of weak X-ray fluxes or flares ranging up to B-class intensity. 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 and Lunt H-alpha solar telescope and QHYCCDIII mono camera for H-alpha imagery, mounted on Skywatcher EQ6 Pro. 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.
