Since the fast has already begun, one cannot make Havdala on Motzai Shabbat, this week.
What one does, once it's Motzai Shabbat:
- Before removing one's shoes and doing any work one says בָּרוּךְ הַמַּבְדִּיל בֵּין קֹדֶשׁ לְחֹל.
The Kitzur recommends one says the longer version:
- Upon seeing a flame, one says the Bracha of בּוֹרֵא מְאוֹרֵי הָאֵשׁ.
Typically this will be done in shul after the Amida; somebody will light a Havdala candle.
If one is not going to shul, one can light one's own Havdala candle for this purpose.
- In the Amida one says אַתָּה חוֹנַנְתָּנוּ like on every Motzai Shabbat.
If one forgets, one does not make amends. However, if one didn't say אַתָּה חוֹנַנְתָּנוּ then one cannot eat after the fast until one has heard Havdala.
- Havdala is done on Sunday night, after the fast.
No candle and no spices. Only wine. Only בּוֹרֵא פְּרִי הַגָּפֶן and the long הַמַּבְדִּיל-Bracha are said.
