"To cancel a double sharp, one now merely writes a single sharp-sign. "When a double flat is cancelled by a single flat, and a double sharp by a single sharp, the traditional practice of placing a natural sign before these is redundant, since a single flat or sharp sign cannot mean anything else." Garner Read (1969) concurs. A half sharp indicates the use of quarter tones, and may be marked with various symbols including half sharp. Gould (2011) refers to 'traditional' and 'contemporary' practice. Less often (in for instance microtonal music notation) one will encounter half, or three-quarter. Now we just write the new one - naturals are only needed when moving into the open key with no sharps or flats! We could compare it with the old style of cancelling a key signature with naturals before writing the new one. But you'll find plenty of older music that does it this way. These are indicated in music by the following symbols. The more modern style is just to write the sharp, even after a double-sharp in the same bar. A sharp takes a note and makes it slightly higher, while a flat takes and makes it slightly lower.

Possibly the F in the preceding bar (which you have just avoided showing us!) was a double-sharp? In that case, the 'natural-sharp' notation, though not strictly necessary, could be a useful cautionary. It's the old notation for a normal sharp when double-sharps (as on the following note) are in the vicinity.
