With banners streaming,
Rode through the fair auroral gate
In mail gold-gleaming.

Till shines the rounded harvest-moon,
And velvet dahlias drink the dew.

O'er an angel-people shine.

Taking flight,
His auroral spirit basks in dreams divine.

Our happy paradise fore-doomed;

Love blooms as helpless as a flower.

In life's grey dusk itself is grey,
And when the curfew of life's day
By death is tolled,
Shall forfeit not the auroral ray
And eastern gold.

Dark Vallombrosa in their dream.

Of Tuscan gold that ruddier shines
Behind a saint's auroral face
That shows e'en yet the master's trace.

In science:

We note that the trend from our ISO-based results disagrees with that found by Dinerstein et al. (1985), who used 52- and 88-µm fluxes and electron densities from KAO spectra of six PNe to derive Te (O I I I)IR values that were systematically lower than Te ’s derived from auroral to nebular [O I I I] line ratios.
A deep survey of heavy element lines in planetary nebulae - I. Observations and forbidden-line densities, temperatures and abundances
However, as discussed in Section 4.2.1, in some cases the [N I I] and [O I I] nebular to auroral line ratios can be affected in ways that result in them being unreliable diagnostics of the temperature pertinent to the lower excitation zones of PNe.

Subscripts ’n’, ’a’ and ’f ’ represent nebular, auroral and finestructure lines, respectively.
Elemental abundances of Galactic bulge planetary nebulae from optical recombination lines
In the case of NGC 6567, various Ne -diagnostic lines yield consistent values of Ne , so a constant Ne has been adopted in calculating Te from the [N I I]na and [O I I I]na nebular to auroral diagnostic line ratios.
Elemental abundances of Galactic bulge planetary nebulae from optical recombination lines
In the calculations, we have adopted Te derived from [N I I]na nebular to auroral line ratio and Ne derived from the [S I I]nn nebular line ratio (or the average of values derived from the [S I I]nn and [O I I]nn ratios if the latter is available).
