Deciphering Solar Magnetic Activity: Spotting Solar Cycle 25

Comparing the evolution of the daily hemispheric sunspot number and a data-inspired representation of activity band polarity and migration image
Friday, June 9, 2017

We present observational signatures of solar cycle 25 onset. Those signatures are visibly following a migratory path from high to low latitudes.

Space weather forecasting capability is six decades behind terrestrial weather forecasting," you will often hear at gatherings of scientists determined to understand the connections between our star and our home on Earth. It is an accurate statement in terms of capability.

On the Connection between Propagating Solar Coronal Disturbances and Chromospheric Footpoints

The Interface Region Imaging Spectrograph (IRIS) provides an unparalleled opportunity to explore the (thermal) interface between the chromosphere, transition region, and the coronal plasma observed by the Atmospheric Imaging Assembly (AIA) of the Solar Dynamics Observatory (SDO).

The Sun, the Moon, and us: American eclipse of 2017

Scott McIntosh

Director Scott McIntosh gave a NCAR Explorer Series Lecture detailing the anticipated great American eclipse of 2017. This lecture was recorded live and is now available to watch!

Dr. Scott McIntosh is Observatory Director in the High Altitude Observatory at the National Center for Atmospheric Research. His primary focus of research is chromospheric dynamics and understanding the physical connectivity between the Sun's cool surface and its considerably hotter corona. 

The Sun's seasonal weather patterns

Scott McIntosh details the Sun's seasonal weather patterns and demonstrates how understanding the formation, interaction and instability of the Sun's activity bands will considerably improve forecast capability in space weather and solar activity over a range of timescales.

A different picture of the interior of the sun

New observational work provides more information about the evolution of the Sun's interior and origins of its enigmatic 11(-ish) solar cycle. The research potentially opens the door to improved forecasting of decadal-scale solar variability.

On the watch for solar superstorms

NCAR solar physicist Scott McIntosh is raising awareness. While the current peak in the 11-year cycle of sunspot activity is on the weak side, the Sun might still produce a major storm at any point.
