SUNSPOT MONITORING – SEPTEMBER 16, 2017

Here are today’s solar images taken from Al Sadeem Observatory, September 16, 2017.

The sky was clear but experienced intermittent light to moderate winds, making the seeing and transparency average to poor at the time these images were taken. read more

FAREWELL, CASSINI!

It has been a bittersweet moment for space exploration enthusiasts. The 3.26 billion US dollar spacecraft Cassini had plunged into the gas giant Saturn at exactly 3:55PM, September 15, 2017 (UAE Local Time) based on the record from National Aeronautics Space Administration (NASA) mission control after an approximately 20-year overall journey across space and Saturn. read more

SUNSPOT MONITORING – SEPTEMBER 14, 2017

Here are today’s solar images taken from Al Sadeem Observatory, September 14, 2017.

The sky was mostly clear but experienced intermittent light to moderate winds, making the seeing and transparency average at the time these images were taken.

The Sun has been quiet in activity over the past 24 hours. Still having a relatively stable magnetic configuration, the lone visible sunspot group AR2680 produced few weak B-class solar flares which will not significantly affect Earth.

The latest sunspot number (based on visual count and Wolf number calculation) is 11.

With this stance, space weather agencies* forecast very low solar activity to continue with minimum solar flare activity, ranging up to C-class intensity. The extent of the frequency and intensity of the Sun’s activity will highly depend on the magnetic flux fluctuations happening in the visible ARs in the coming days. Close monitoring is being conducted by numerous space weather agencies for any significant development.

ASTEROID FLORENCE CLOSE FLY-BY

On the evening of September 1, 2017, Al Sadeem Astronomy (ASA) Observatory observed the closest flyby of asteroid 3122 Florence. The asteroid was sighted and captured through the observatory’s 16” Meade LX850 Compound Telescope and a typical DSLR camera. read more

A WEEK OF AN ENERGETIC SUN

Size Comparison of AR2673 to Earth (White-light Monochrome Solar Image taken last September 5, 2017 from Al Sadeem Observatory)

Last week was a very interesting week for solar observers and space weather enthusiasts.  In spite its relatively quiet state as it heads towards solar minimum, our parent star, the Sun unleashed its dynamic state. Several active sunspot groups and its associated flaring activity were observed from both ground and space-based observations. Here is an overview of the series of significant solar activity events for the past week. read more
