Deciphering Solar Magnetic Activity: 140 Years Of The `Extended Solar Cycle' -- Mapping the Hale Cycle
Scott W. McIntosh, Robert J. Leamon, Ricky Egeland +6
We investigate the occurrence of the "extended solar cycle" (ESC) as it occurs in a host observational data spanning 140 years. Investigating coronal, chromospheric, photospheric a…
The Extended Solar Cycle Tracked High into the Corona
S. J. Tappin, R. C. Altrock
We present observations of the extended solar cycle activity in white-light coronagraphs, and compare them with the more familiar features seen in the Fe XIV green-line corona. We…
Forecasting the Maxima of Solar Cycle 24 with Coronal Fe XIV Emission
Richard C. Altrock
The onset of the "Rush to the Poles" of polar-crown prominences and their associated coronal emission is a harbinger of solar maximum. Altrock (Solar Phys. 216, 343, 2003) showed t…
Coronal Fe XIV Emission During the Whole Heliosphere Interval Campaign
Richard Altrock
Solar Cycle 24 is having a historically long and weak start. Observations of the Fe XIV corona from the Sacramento Peak site of the National Solar Observatory show an abnormal patt…
The Progress of Solar Cycle 24 at High Latitudes
Richard C. Altrock
The "extended" solar cycle 24 began in 1999 near 70 degrees latitude, similarly to cycle 23 in 1989 and cycle 22 in 1979. The extended cycle is manifested by persistent Fe XIV coro…
