These are extensions across the solar disk of elonged bright mottles which originate in the central regions of clusters of mottles. They are best observed on good filtergrams at H ± 0.5 Ǻ through comparison with filtergrams at other positions on the line profile. Their length can be as much as 200 seconds of arc. The bright streaks appear to be predominantly horizontal loop strructures, while the well-known spicules are mainly vertical structures. A bright streak may be well defined or rather diffuse along its length and many of them are accompanied by darker boundaries or envelopes. It is usual to find a loop of birght streak bridging the central areas of two mottle clusters. It seems that the observed pattern in the space between the chromospheric network at H ± 0.5 Ǻ results partly from the interactions of the bright streaks of different stages of evolution traversing the area in different directions.
